You will notice the blurred background on the login screen right away when you start your Windows 10 computer that’s running the v1903 and up. This kind of blurred background is known as “Acrylic Blur Effect on Sign-in Screen”. This new feature delivers a beautiful experience to users by adding more focus to the login screen. However, no matter how nice this feature is and even if it only stays for less than a minute, not all users like it and if you’re one of these users, read on as this post will guide you in disabling the blurred background login screen in your Windows 10 computer. Disabling the blurred background in the login screen can be done in two methods. The first one is via the Registry Editor and the second one is via the Group Policy Editor. Before you proceed, make sure that you are using an admin account and you must create a System Restore point first. Once you have that covered, follow the options provided below.

Option 1 – Disable the Blurred background in the login screen via Registry Editor

• First, tap the Win + R keys to open the Run dialog box and type “Regedit” in the field, and hit Enter to open the Registry Editor.
• After that, navigate to this registry path: KEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsSystem
• Next, right-click on any empty space in the right pane and create a new DWORD (32 bit) and name it as “DisableAcrylicBackgroundOnLogon”.
• Once you’ve created the DWORD, double click on it and set its value to 1 to disable it and 0 to enable it.
• After you make the necessary changes, restart your computer. You won’t now see the blurred background on the login screen.

Note: No matter what option you select to change the background, it will stay blurred when you click on the login button. At the time of writing, there is no way to disable this feature in the Personalization section so the Registry Editor will have to suffice for now.

Option 2 – Disable the Blurred background in the login screen via Group Policy Editor

• Tap the Win + R keys to open the Run utility and type “gpedit.msc” in the field and tap Enter to open the Group Policy Editor.
• After that, navigate to this policy setting: Computer ConfigurationAdministrative TemplatesSystemLogon
• From there, double click on the “Show clear logon background settings” and since its default value is “Not configured”, set it to “Disabled”. You will see the following description under this setting:
  • “This policy setting disables the acrylic blur effect on the logon background image.”
  • “If you enable this policy, the logon background image shows without blur.”

• Now click on OK and then check the login screen.

Note: If you don’t configure or if you disable this policy, the logon background image adopts the acrylic blur effect. However, if it didn’t work, you have to restart your computer and then check.

If you are using a Windows Update Standalone Installer to install Windows Updates in your Windows 10 computer but you suddenly encounter an error saying, “Installer encountered an error: 0x80096002, The certificate for the signer of the message is invalid or not found”, read on as this post will guide you on how you can fix it. This kind of error could be due to the vendor’s certificate that might have become invalid, compromised, or pulled. Aside from that, it is also possible that the update is not targeted at your OS version. You could get this error when you try to install an incompatible update or software on your computer. This error can also appear due to misconfigured system files or when you try to install BitLocker To Go Drive Encryption or BitLocker Drive Preparation Tool. To fix this error, you can try to run the standalone installer in Compatibility mode or enable the Windows Identity Foundation or run the Windows Update troubleshooter. Make sure to check if the error was resolved after every suggestion. It will help you learn what fixed the problem.

• Look for the setup file.
• Once you find it, right-click on it and select Properties from the context menu.
• After that, go to the Compatibility tab and mark the checkbox for “Run this program in compatibility mode for:” and from the drop-down list, select the Windows OS version you want the installer to run on.
• You also have to check the “Run as administrator” option.
• Now click the Apply button and then click OK to save the changes made and check if it has resolved the issue or not.

Option 2 – Try to troubleshoot compatibility

This option is almost the same as the first one except it is an alternative way of fixing the error 0x80096002 in case the first one didn’t work. In this option, you will troubleshoot the compatibility issue.

• Look for the setup file.
• Then right-click on it and select the “Troubleshoot compatibility” from the context menu.
• After that, click on the “Try recommended setting” option. Once the process is done, the error message should be gone.

Option 3 – Try to enable the Windows Identity Foundation

You might also want to enable the Windows Identity Foundation as some users reported that it helped in resolving the error for them. To do so, follow these steps:

• In the Windows Start Search, type “Turn Windows features on or off” and click on the matching result.
• This will open a list of Windows Features and from there, look for the Windows Identity Foundation.
• Once you found it, click on its checkbox and click OK to enable it and save the changes made.
• Now see if it has fixed the error or not. If not, you have to disable the feature.

Option 4 – Run the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter is one of the things you can first check out as it is known to automatically resolve any Windows Update errors like error 0x80096002. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

If you are using a Windows 10 PC that has different processors clubbed together, chances are you might encounter an error saying, “MULTIPROCESSOR CONFIGURATION NOT SUPPORTED” during a Windows upgrade or software installation. This error is actually caused by a bug check with a value of 0x0000003E. This error also indicates that the processors in your computer are asymmetric in relation to one another. So if you want to upgrade you need to have all the processors of the same type and level. But worry not for this guide will help you in fixing this error. The MULTIPROCESSOR_CONFIGURATION_NOT_SUPPORTED error can occur in several cases such as during an installation of Windows 10, or when the driver is loaded, or when Windows Start or Shutdown and the chances of you getting a blue screen is very much high. To fix this error, refer to the options given below and make sure to follow them carefully.

Option 1 – Try to disable the Hyper-Threading in your BIOS

Hyper-Threading in the BIOS lets a processor (multi-threaded) run various tasks in a simultaneous manner. To disable this, here’s what you have to do:

• Restart your computer and boot into it right after. To do that, tap the F2 key.
• Once you’re in the BIOS, locate the Hyper-Threading option which should be located under the Performance section along with other options like Multi-core support, Rapid Start technology, and many more.
• Disable Hyper-Threading and then make sure to save the changes and exit BIOS.

Note: Although Hyper-Threading is only used when necessary, there are some OEMS that don’t have the option to disable it and if that’s the case, you need to try other options given below.

Option 2 – Try to disable the Virtualization in the BIOS

Virtualization in the BIOS allows users to run a single physical resource such as the server or storage device to appear that it is running as multiple logical resources. It is also properly termed as “HYPER-V”.  To disable it, refer to these steps:

• Boot into the BIOS as you did earlier.
• Then look for the Security options.
• After that, from Security options, look for Virtualization Technology or VTX among the options given.
• Then turn it off and restart your computer.

Note: Although Windows 10 offers features such as the Device Security for Core Isolation and Memory Integrity, if you turn them off at the software level, it will not help at all. If you’re able to resolve the error, you can do some further research and see what software or hardware you can use to further help you.

Option 3 – Try checking if there are any BIOS updates available for your PC

Updating the BIOS may help you resolve the MULTIPROCESSOR CONFIGURATION NOT SUPPORTED error. You can just go to the OEM’s website as they offer utility software that can download BIOS firmware and update it without any problem. BIOS updates usually offer enhancements and fixes to some issues like this one.

Error Code 0x80070005 – What is it?

Error code 0x80070005 is also known as the “Access Denied” error code because it prevents Windows users from accessing updates on their machines. This error code exists due to a lack of permissions on one’s system files or registry, permissions which are necessary for the updates via Windows Update to complete successfully. Error code 0x80070005 affects multiple versions of the Windows operating system including Windows 8, 8.1, and Windows 10.

Solution

Error Causes

The lack of files or registry permissions which result in the presence of error code 0x80070005 on your device may occur based on several reasons.

How to Easily remove Solimba from your system

What is Solimba?

Solimba is a bundled executable program. It was created to be launched as a promotional tool to get advertisements loaded on a user’s system, upon installation. As a bundle, Solimba offers installation of various programs, with the objective of promoting various products and services. It utilizes unethical techniques, as in the case with adware tactics to influence or for want of a better word, hijack an Internet Browser to affect a website’s result on a search results page. In this assessment, Solimba distributed ads on Internet Explorer, Chrome, and Mozilla browsers, by hijacking various Internet Browsers to change the user's experience. (Images are shown below) Technical details about Solimba PUP include:

Digital Signature:  POPELER SYSTEM, S.L. Entry Point:   0x0000C1DC

Assessment of Solimba Potentially Unwanted Program

Solimba PUP is all about the ads. Once this executable is installed, it penetrates your computer system and sends ads all over your Internet Browser – Chrome, Internet Explorer, Mozilla Firefox, and the likes. For this assessment of Solimba.exe PUP, two installations were carried through. In layman's terms, I actually installed Solimba on two occasions to decipher the true nature of the PUP. It was shocking to find that both installations revealed different bundled programs and advertisements. In the first instance (as shown below), Solimba proved more aggressive in featuring ads for revenue advancements.

 Solimba employed aggressive advertising techniques

It’s important to note that hijacked results resulting from the installation of Solimba. This affected the results of the website on the Internet browser to boost its ranking, even without the use of a search engine. The advertisement displayed on the Internet Explorer search page routes the user to a software installation website. The utility tool in question was a “Windows 8.1 PC Repair” tool used to identify threats present on the Windows 8.1 OS. The advertisement displayed on the Chrome Browser search page routes the user to a health and beauty magazine website. This site advocates health and beauty, especially issues concerning weight loss. Several ads were visible on-site, displaying products to assist people in losing weight. During my installation of Solimba, the installation wizard underscored that four programs would be downloaded. These programs included N8Fanclub.com_KinoniRemoteDesktop, Lolliscan, PaceItUp, and SearchProtect. Interestingly, only two programs from the list were apparent or obvious. An N8Fanclub.com_KinoniRemoteDesktop file was made on the Desktop and SearchProtect was seen in “All Programs”, along with files stored on the computer’s Local Drive. The other programs that were “supposedly” installed remained concealed. A test was done to determine whether these were counted as extensions or add-ons to the varying web browsers but nothing was found on any of the tested browsers – Google Chrome, Internet Explorer, and Mozilla Firefox.

Description of 4 Installed Files

N8Fanclub.com_KinoniRemoteDesktop

When this file was initially found on the Desktop, a rootkit came to mind. A rootkit was used as a means to an end. Whoever was on the receiving end of this unwanted file would be able to connect to an infiltrated system without the knowledge of the user. After running the file to determine its behavior, nothing much happened. A message appeared indicating that the software couldn’t execute on the computer. That was pretty tricky since, to begin with, I didn’t place that specific file on the desktop but it came along with the territory and so I had to accept it. Further research online into N8Fanclub.com_KinoniRemoteDesktop proved very rewarding. A search of the entire file name was not able to do the trick so I had to do research on both terms separately. After landing on N8Fanclub.com, I was nicely asked to disable my adblocker. There seemed nothing harmful about the site. However, due to the fact that it was not what I initially installed, the program was an unwanted program. That’s exactly what Solimba does. It installs several other programs that were not requested by the user in an attempt to make money from advertising. The mere fact that this program got installed meant that it was to promote an online service.

KinoniRemoteDesktop

was a separate program. It was combined with N8Fanclub as a way to allow users to use their PC computer “as if they were sitting in front of it.” A user would be able to make use of a full web browser, watch Flash videos, play games, and even use office applications. This would be done from the user’s Nokia device. This is an advertisement at its best.

Lolliscan

This program did not allow me to see much since it didn’t leave a physical trace behind. However, during the installation, Lolliscan was listed as one of the four programs that would be installed. Overall, Lolliscan supposedly should be able to save people money since this form of the ad focuses on showing coupons when visiting sites such as Amazon. While this seems like a good deal, this ad will invade your personal space and distribute pop-ups at the most inopportune times.

PaceItUp

As the name states, PaceItUp is software added to a browser with the intent to speed your computer. Quite the contrary, PaceItUp does the total opposite since it installs bundled programs that slow down a computer system. PaceItUp is also known for displaying ads and tracking what the user does on his/her computer system.

SearchProtect

It’s known for hijacking your computer’s homepage. In fact, this addition is very stubborn and often possesses a challenge when a request to uninstall is made.

Further Information on Solimba

The second installation of Solimba also had its own dose of bundles to display. In comparison to the first installation, two programs from the bundle were different while two remained the same. two additional programs were installed along with the second installation of this bundle. These were dubbed Optimizer Pro and GamesDesktop. SearchProtect and N8Fanclub.com_KinoniRemoteDesktop remained triumphant and unbeatable. They were repeated within the installation. To completely remove Solimba from your computer, click here to download and install Spyhunter.

Gaming on the computer has become one of the most used past-time activities among people of all ages. And since we are still in pandemic it has only risen as activity. People can acquire a lot of games at various discounts on various platforms and enjoy them at the leisure of their home. Among many game platforms and stores, Electronic art's Origin is one of the bigger ones, and having some titles that could not be found anywhere else coupled with the ability to have access to almost the whole game catalog with one monthly subscription make it one of the most used clients. Sadly as with every piece of software Origin's client is not perfect by any means and it can behave strangely from time to time. Hello everyone and welcome to errortools.com, today we will fix Origin error code 10 which oddly enough can appear out of nowhere and can even appear on the very end of installation for the chosen game. If you have managed to come by this error you are in luck to be here because we have a couple of fixes for it. I know that you might be excited to play the game so let's go and do some fixing

Check Server status

Before diving into technicality and before we start deleting files and fixing things you should check the Server status. This seems maybe like something you should not do but if the server has experienced some kind of downtime or it is in maintenance Origin will throw this error in the client. Unexpected situations can cause various server issues all of a sudden and the first thing is to check are servers online and working. There are various ways to check server status from official origin website to Electronic arts twitter channel to Reddit and many more online server status websites. If it turns out that the server is to be blamed for this error then sit back and wait for EA to resolve the issue, there is not much you can do anyway.

Delete OriginThinSetupInternal.exe

• After some research, it has come to light that originthinsetupinternal.exe can cause this specific error. The best solution is to delete the file and then run Origin as administrator so the file is remade new.
• First, make sure that Origin is fully closed, check the taskbar and if it lurks there right-click on it and click on quit
• Run file explorer and go into the folder where Origin is installed, by default it is C:\Program Files (x86)\Origin
• Locate OriginThinSetupInternal.exe and delete it
• Then locate origin.exe and right-click on it and then click on Run as administrator

Reinstall Origin client

If the previous solution has not solved the issue then Origin might have some corrupted files inside it. It is known that the Origin client can produce some bad files if the installation has been forcefully canceled. The best thing is to reinstall the completely whole client.

• Press ⊞ WINDOWS + R to open the run dialog
• Inside run dialog type in Control panel and press ENTER
• In the control panel locate programs and features group and double click on it
• Locate Origin, click to select it, and on top click on uninstall
• After uninstall process is completed start file explorer and go to the folder where Origin was installed, by default it is C:\Program Files (x86). Locate the Origin folder and delete it.
• Go to the official origin website and download the new client installation.
• After the download is finished double click on it and follow onscreen instructions.

Disable antivirus

If every solution so far has not been able to remove error then obviously something else is interfering with the origin client and installation functioning. Altho not advisable, turn OFF your security suite including both firewall and antivirus and try installing the game again. There is the possibility that the origin client or some game file has been marked as false positive by security software thus preventing it from executing properly.

How to Fix Error Code 0x8007041d on Your PC

Error Code 0x8007041d - What is It?

Error Code 0x8007041d is an error that arises during the Windows 10 Update process. In some cases, this error code can also arise during the Windows 10 Activation process. It is an error code that has been present in multiple versions of the software but usually arises when antivirus or registry issues interfere with the Windows Update or Activation software.

Common symptoms include:

• Inability to download the needed Windows 10 updates
• Inability to complete the Windows 10 Update process

If you are experiencing the Error Code 0x8007041d on your machine, there are several methods that you can use to attempt to resolve the problem. Several of the steps that are most successful for the resolution of this error require familiarity with registry and antivirus tools, so if you are unsure of your ability to complete these steps on your own, contact a qualified computer repair technician to assist you.

Solution

Error Causes

In most cases, Error Code 0x8007041d arises when there is a conflict between multiple antivirus or malware tools on the computer, if there is an issue in the Windows registry, or if your Windows Defender software is out of date. During the Windows Update process, the system checks to ensure that there are not any factors that are present that could introduce viruses to the system, so if there are any indicators that could present issues to the software, Error Code 0x8007041d will often arise.

Further Information and Manual Repair

For users who experience Error Code 0x8007041d, there are several steps that can be taken to resolve the issue. If the following methods are not successful for you or if you are unsure of your ability to undertake them on your own, contact a qualified Windows 10 computer technician.

Here are the best ways to attempt to fix Error Code 0x8007041d on your computer:

Method 1:  Remove Additional Security Software Apart from Windows Defender

In some cases, having multiple versions of malware or antivirus software installed on your computer can cause the Windows system to create conflicts between them, which can interfere with your ability to update. During the update process, the system may attempt to determine if there is any malware present, and having multiple kinds of antivirus software present on the same machine may return mixed results.

If you currently are running antivirus software that is separate from Windows Defender, consider removing it from your computer prior to running the update software. This may allow you to successfully complete your update process without conflict. Additional software can be reinstalled after the update is complete, but make sure to keep both sets of software up to date in order to lessen the chances of encountering this error code again during future updates.

Method 2:  Update Your Windows Defender Software

If you currently have Windows Defender as your primary antivirus software, check to see whether it is fully up to date. Out of date antivirus software can cause conflicts with the Windows Update process since the update to Windows 10 will not be able to be completed unless the system is free from viruses or malware.

If you are unsure of whether or not your Windows Defender is up to date, open it and run the process to check for updates, then re-attempt to run Windows Update. In some cases, you may want to restart your computer before running the Windows 10 Update process a second time.

Method 3:  Run the Registry Repair Tool

Another issue that could cause Error Code 0x8007041d is a problem in the system registry. If you believe that this may be the case, run the Windows Registry Repair Tool on your machine to check for and resolve any issues. This is a fairly simple and straightforward tool to use, but it can help you to resolve any number of problems that may interfere with your ability to update your Windows 10 software.

If you have taken the steps listed above, restart your computer before attempting to proceed with the Windows Update process. If the three methods listed above are not successful in completely resolving Error Code 0x8007041d on your machine or if you are not comfortable in your ability to implement these steps on your own, contact a qualified Windows repair technician who is familiar with the Windows Update process to assist you.

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

Microsoft’s initial Windows 11 hardware requirements were not really well received by users and they were not really clearly represented from the start making a lot of potential customers slowly drift away from the hype. It seems that Microsoft has acknowledged this since they have changed their tune about system hardware requirements for the upcoming Windows 11. It seems that Windows 11 will be able to be officially installed on unsupported computers but with a little inconvenience.

What is a catch?

Windows 11 will still have the same hardware requirements and if the PC meets them, that computer will be officially supported, other ones (any that can run Windows 10) that do not meet system requirements can still run Windows 11 but the system will have to be clean installed. So no upgrade option for old computer users, just a clean install. This means of course that you will need to download the ISO image and make a bootable USB in order to install it. Also since you will be doing a clean install do a backup of the hard drive since it will need to be formatted. Also, Microsoft has stated that with unofficially supported PC some driver updates might not be delivered leaving you with either older driver versions or relying on your hardware manufacturer on them. This is still not confirmed by Microsoft, just stated as an option. We will see how it goes.

Conclusion

It is very good that Microsoft has reconsidered its system requirements and will not stubbornly push its initiatives over the top requirements allowing even older computers to install new OS. I am sure over time lot of users will upgrade their hardware and drive into officially supported waters, but it is good that they will be able to use new OS on their current hardware.

If you encounter a Blue Screen error that points out to the CMUDA.sys, read on as this post will guide you in fixing it. The CMUDA.sys file is a Windows operating system driver file that is related to the USB Device Audio capabilities of a computer. There are times when this file causes Blue Screen error due to some conflicts in RAM or some incompatible firmware or hard disk issues, corrupted drivers or malware infection, and so on. There are various Blue Screen errors that are related to the CMUDA.sys file such as:

• KMODE EXCEPTION NOT HANDLED
• PAGE FAULT IN A NONPAGED AREA
• IRQL NOT LESS OR EQUAL
• SYSTEM THREAD EXCEPTION NOT HANDLED (CMUSBDAC.sys)

In most cases, the CMUDA.sys file usually triggers the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED Blue Screen error. Although this Blue Screen error may seem complicated, its workarounds are straightforward so you won’t have any problems in following them.

Option 1 – Try to update or rollback your device drivers

If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• After opening the Device Manager, locate the device drivers that are marked with a small yellow exclamation mark icon and right-click on each one to open their Properties. On the other hand, you can also look for sub-entries under Sound, video, and game controllers like the C-Media USB Audio Class
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer. You can download the as C-Media USB Audio Class driver from the cmedia.com website.

Option 2 – Try to recreate the CMUDA.sys file

The first thing you can try is to recreate the CMUDA.sys file. Every time your Windows 10 PC boots up, it looks for all the system drivers in place and if it is unable to find them, it tries to create them. Which is why if you remove your corrupt driver file, chances are, you might get a fixed file recreated just for you. How? Refer to the steps below.

• Boot your Windows 10 PC in Safe Mode.
• Then open File Explorer and navigate to this location: C:/Windows/System32/drivers
• From there, look for the file named sys and rename it to CMUDA.old.

Note: As you can see, the file’s extension has changed from .sys to .old.

• Now restart your computer and check if the CMUDA.sys Blue Screen error is now fixed.

Option 3 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• After that, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

On the other hand, you can also try running the online Windows 10 Blue Screen troubleshooter from Microsoft. It is a wizard that could help you fix any Stop errors related to the CMUDA.sys file and will offer you helpful links as you use it.

Option 4 – Try running the DISM tool

You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the Wdf01000.sys Blue Screen error. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 5 – Run System Restore

Running System Restore might also help in fixing Blue Screen errors related to the CMUDA.sys file.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.
