As you know, one of the most highlighted features of Windows 10 is Windows Updates. It was offered to the customers as a service rather than a product with the release of Windows 10 under the scenario of Software as a Service which led to Windows Updates being set by default on Windows 10 and without an option for any users to disable it. Although not all users are happy with what Microsoft did, this is an ultimate step towards the greater good of all its customers since Windows Updates helps users in keeping their computers secured against all kinds of threats as well as provide them with the greatest and latest updates from Microsoft. So if you are one of those users who approved of the Windows Updates service, then read on as this post will guide you in running Windows Updates from Command Line either via Command Prompt or Windows PowerShell. For the complete set of instructions, refer to the options given below.

Option 1 – Run Windows Update via Command Prompt

Command Prompt in the Windows operating system exists for a very long time now compared to the comparatively new Windows PowerShell. That’s why it has similar capabilities to run Windows Updates. However, the highlighting point here is that you don’t have to download any module for Windows Updates. To get started running Windows Updates using Command Prompt, refer to the steps below.

• First, type “cmd” in the Cortana search box, and from the search results, right-click on Command Prompt and select the Run as Administrator option to open it with Administrator privileges.
• If a User Account or UAC prompt appears, just click on Yes to proceed.
• Next, type in the commands listed below, and don’t forget to tap Enter right after you type each one of them.
  • UsoClient StartScan – use this command to start checking for updates.
  • UsoClient StartDownload – use this command to start downloading updates.
  • UsoClient StartInstall – use this command to start installing the downloaded updates.
  • UsoClient RestartDevice – use this command to restart your computer after you install.
  • UsoClient ScanInstallWait – use this command to check, download and install updates.

Note: Keep in mind that the commands in Command Prompt listed above are only meant for Windows 10. On the other hand, if you are using an older Windows version, you can try using the following commands instead:

• wuauclt /detectnow – use this command to start checking for updates.
• wuauclt /updatenow – use this command to start installing the updates detected.
• wuauclt /detectnow /updatenow – use this command to check, download and install updates.

Option 2 – Run Windows Updates via Windows PowerShell

If you run Windows Updates in the Windows PowerShell, it will require you to install the Windows Update module manually. Hence, you have to get the Windows Updates downloaded and install Windows Updates.

• Search for PowerShell in the Cortana search box and then run it with administrator privileges.
• Once you’ve opened the Windows PowerShell, type the following command and hit Enter.
  • Install-Module PSWindowsUpdate – use this command to install the Windows Update module for Windows PowerShell.
  • Get-WindowsUpdate – use this command to connect to the servers of Windows Update and download the updates if found.
  • Install-WindowsUpdate – use this command to install the Windows Updates you’ve downloaded to your computer.

Recently, a number of Windows 10 users reported that they were not able to use Cortana properly because it wasn’t able to connect to the internet. According to these users, Cortana won’t connect to the internet even when their internet connection is stable. According to security experts, this issue is confirmed to occur only with Microsoft accounts. This problem might have something to do with a proxy server that interferes with Cortana. There were reports that this issue was caused by a proxy that was filtering the network connection which also happens to interfere with Cortana’s ability to adapt search results and queries based on the user’s location. It could also be caused by some glitch in the home network or your Microsoft account information is inconsistent or your Microsoft account has to be verified. Here are some suggestions that could help fix the connection issue in Cortana, just start with the first one and work your way down until you encounter an option that fixes the problem.

Option 1 – Restart or reset your modem or router

The first thing you can try is restarting or resetting your modem or router. All you have to do is unplug the power cable of the modem and then plug it back in after a few seconds. You could also use the reset button of the modem at the back if it is one. But before you press the reset button, keep in mind that it will erase all the connection credentials and it will be set back to its default settings. After rebooting the network, you can restart your computer to force your modem or router to reassign an IP address to your computer.

Option 2 – Restart Cortana

Restarting Cortana can help you resolve the issue.

• To restart Cortana, open the Task Manager, right-click on Cortana and select the “End process” option.
• Then go to the File tab and select “Run new task”.
• After that, type in “cortana.exe” and press Enter to restart the process.

Option 3 – Try to remove Proxy

Removing the Proxy might also help you in fixing the connection issue in Cortana. Here’s how you can do it:

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it.

Option 4 – Open another app that uses a Microsoft account

This might seem like an odd fix, however, a couple of users tried doing this and it worked for them as it allowed Cortana to connect to the internet again. In this option, you just have to launch another app that uses your Microsoft account information in the same way as Cortana, for instance, the Store app. Once you open the app, a prompt should appear along with a dialog box that allows you to update your Microsoft account with the information required. After that, restart your computer and check if Cortana is now able to connect to the internet or not.

Option 5 – Verify your Microsoft account

In some cases, Cortana might not be able to connect to the internet because your Microsoft account is no longer verified. This usually happens when you use a two-step authentication system with your Microsoft account. To verify it, just open Settings and click on Accounts. After that, check if you have a Verify hyperlink under your Microsoft account or not then click on Verify. Afterward, follow the next on-screen prompts to verify your Microsoft account. Once your account is verified, restart your computer.

Option 6 – Reset Cortana settings

• Open Cortana and go to the Settings section where you’ll see the “Turning off Cortana clears what Cortana knows on this device, but won’t delete anything from the Notebook. After Cortana is off, you can decide what you’d like to do with anything still stored in the cloud” option. Turn this option off.
• Restart your PC.
• After your computer boots, launch Cortana again and check.

If you got an Activation Error 0xC004F211 after having installed or upgraded your Windows 10 PC, then this indicates that some hardware in your computer has changed which’s causing the error to pop up. Windows might not be able to determine if the key is used on a new computer or if it’s still the same one if you have just removed or upgraded old hardware. But worry not for this post will guide you in fixing the Windows Activation Error 0xC004F211 on your Windows 10 computer. When you encounter this error, you will see the following error message on your screen:

“Cannot activate Windows 10. Try activating again later. If that doesn’t work, contact support. Error code: 0xC004F211.”

Note that although hardware changes cause this error, the minor ones don’t really cause any issues with activation, however, if you have made any significant hardware change such as replacing your motherboard, it will most likely cause the activation error. In such cases, the Windows Activation system will treat this as new hardware and you will need a new license for that. Even if your Windows 10 computer has a genuine key, it might still fail to get activated which results in the Windows Activation Error 0xC004F211. Thus, before you do other troubleshooting steps, you need to run the Windows 10 Activation Troubleshooter first. To do so, follow these steps:

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

In addition, there is an exception offered by Microsoft – if you are connected to a Microsoft account prior to the hardware change, then you can most certainly use the same license key to reactivate Windows 10 again. Microsoft calls this an “Exception path” which should be fixed easily by the Windows Activation Troubleshooter as pointed out earlier. However, if the Windows Activation Troubleshooter isn’t able to resolve the error you can try purchasing a new license. In such rate case, even if you do have a Microsoft account available on your Windows 10 computer, and if Windows was never activated, this solution will not work. And if you haven’t connected your Microsoft account with your Windows 10 computer prior to the major hardware change, then your only option left is to purchase a new license. For you to do that here are some steps you can follow.

• To purchase a new Windows license, the first thing you have to do is click on the Start button > Settings > Update & Security.
• From there, go to Activation and select the “Go to Microsoft Store” option.
• After receiving your new license, you need to go back to Update & Security then go to Activation and select the “Change product key” option.
• Now update your Windows 10 computer using the new key and it should automatically activate your computer.
• Next, you have to create a Microsoft account or connect your existing local account to your online account.
• Once the system links the key and the account, you need not buy a new license in case something like this happens again.

Note: If you are an IT administrator, you need to keep in mind that there is a limit to the number of times you can reactivate Windows on your computer. Moreover, if you don’t see any option to reactivate the license, and it is a work computer, you need to contact your organization’s tech support.

Windows defender error 0x800700AA, service can not be started comes when the user is trying to run Windows defender scan on their system. This kind of behavior happens for two reasons mostly, third-party application conflict or corrupted system files. In this article, we will tackle both scenarios and provide you with solutions in both cases.

Use third party automatic solution

If you are not tech-savvy or you do not wish to manually tackle with Windows system you can use RESTORO (guide and download link below) to automatically repair this error. RESTORO will automatically scan your system and fix all errors with just a single click of a mouse. If you wish to fix the error manually keep on reading.

Third-party application conflict

In this rare scenario when Windows defender can not start scan due to conflict with installed service or application in the system solution is quite simple. Restart your PC into safe mode and run the scan from there. In a safe mode environment, minimum drivers and services are only loaded eliminating any conflicts that might occur when everything is booted. If Windows defender can not run the scan in safe mode and you get the same 0x800700AA error then you can eliminate application conflict as a reason and move to the next solution which will tackle corrupted system files. If you, however, managed to run a scan then you have a rare third-party application conflict, you can boot normally into windows and try to eliminate one by one to see which one is causing the issue. The safest bet would be to start with security software because most of the time that is what causes conflicts in running services and applications.

Corrupted system files

If the previous solution has not provided you with results then you have system file corruption that needs to be fixed. Move from one solution to another as presented below:

1. Run SFC scan

   SFC scan is a built-in Windows tool for solving corrupted system files issues, it is fully automated and does not require from the user any kind of knowledge or information. To run it and scan the system do the following: Press ⊞ WINDOWS + X to open the secret menu Left-click on the command prompt (admin) In command prompt type SFC /SCANNOW and press ENTER Wait for the process to finish, do not interrupt it and once it is done, restart your computer

2. Run DISM scan

   DISM scan is similar to SFC scan but it tackles different types of system file corruption and it is recommended to run it also after SFC has been completed. Please note that for DISM scan to be successful you will need a stable internet connection since DISM will replace corrupted files with new ones downloaded from Microsoft. To run it do the following: Press ⊞ WINDOWS + X to open the secret menu Left-click on the command prompt (admin) inside command prompt type: exe /online /cleanup-image /scanhealth followed by ENTER, then type: Dism.exe /online /cleanup-image /restorehealth also followed with ENTER. Leave scan to finish and reboot your PC

The GDI32.DLL is a DLL (Dynamic Link Library) file that was developed by Microsoft. It is an essential file of the Windows OS as it contains instructions and information for exe files to follow. These DLL files also use to store the various procedures and codes for the Windows programs. It is considered an essential component of Windows because it ensures that all the programs on Windows are operating properly. So, if the gdi32.dll not found on your computer, then it can negatively impact your computer and the associated programs. Though DLL files used to be so efficient and convenient, they are extremely vulnerable to errors and issues.

1. Perform SFC scan

   Press ⊞ WINDOWS + X to open the Windows menu From the menu choose command prompt (admin) In command prompt type sfc /scannow and press ENTER Leave the computer for the operation to be completed and Reboot your computer

2. Run DISM

   Press ⊞ WINDOWS + X to open the Windows menu From the menu choose command prompt (admin) in command prompt type: DISM.exe /Online /Cleanup-image /Restorehealth and press ENTER wait for the process to be finished and Reboot your computer

3. Update device driver

   Go to your manufacturer's website and update drivers for your components with the latest versions.

4. Update Windows

   If you have an update ready for Windows, update it and see if this will remove the error

5. Scan computer for malware

   Perform a full PC scan for malware to see if this is causing issues with the GDI32.DLL error.

6. Download file

   One solution is to download a file from the official site and place it in the corresponding folder.

7. Perform System restore

   Rollback system restore before the issue happened and your Windows will be working as intended

Despite popular belief, there are a lot of users running Linux OS. Linux offers great security and working environment and 96.3% of the world's top 1 million servers run on Linux. 90% of all cloud infrastructure operates on Linux and practically all the best cloud hosts use it. But gaming on Linux is limited, enter Steam proton a Valve’s gaming solution.

What is Steam proton?

Proton is a WINE fork with some extra capabilities, to play games and run applications not native and not made to run natively under Linux OS. It is supposed to bridge the Gaming issues for PC users and let them more freedom in choosing an operating system to game on.

Find out if your game supports Proton

Although there are a lot of titles that nowadays run natively on Linux some will still need proton in order to run at all and sadly some of them will not be able to run on Linux even via proton but seeing how Valve is busy and it is trying to push its ideas and technology slowly this gap is closing. In order to see how the game you want to play performs and behaves on Linux and proton environment visit https://www.protondb.com/ and find out. As soon as the site loads you will be greeted with statistics and a search option to find out the status of the desired game with one of the given statuses: Borked, Bronze, Silver, Gold, Platinum, and Native. As you probably guessed native means that the game will work on Linux out of the box and borked will probably not work at all. Platinum and gold status means that game will run on proton without any input or tweaks from the user while silver and bronze means that it will work but might need some tweaks in order to make it work.

How to get Steam proton?

In order to run games under proton inside Linux, you will need firstly a Steam client which luckily works naturally on Linux. Unlocking/activating Steam Proton on your Linux-based system is easy. Just head over to Steam > Settings > Steam Play and toggle the option “Enable Steam Play for Supported Titles”. Valve has tested and fixed some Steam titles and you will now be able to play those titles. However, if you wish to go even further beyond, and play titles that even Valve has not tested, toggle the option “Enable Steam Play for all titles”.

Conclusion

Even we are not there yet, native gaming on Linux is gaining a foothold each day. Will Steam’s OS with proton technology be one that will turn the tide from Windows or some other tech we cannot tell but one thing is for sure, more choices mean better products so I am hopeful for a bright future.

Repair Error 0x00000024

What is Error 0x00000024?

Error 0x00000024 can be seen when you start up and a screen comes up asking which mode you would startup in. Regardless of the mode you select, it leads up to the Windows screen with the loading bar and your computer crashes from there onwards. When you press F8 in order to select the “Disable Automatic Restart On System Failure” option, that is when this error shows up:

ST0P 0X00000024 (x00190203, 0x82700550, 0xc000012, 0x00000000)

Due to this error, both Safe and Normal modes become inaccessible.

Solution

Error Causes

If you’re having this error then it is the indication of an issue with the file NTFS.sys. Further, there might also be problems with the IRP (Interrupt Request Packet) or the disk may have been corrupted. There are multiple other causes of this error, including heavy fragmentation of your hard drive or problems caused by your antivirus software.

Further Information and Manual Repair

First and foremost, you are suggested to run Chkdsk. In order to do this, you have to enter your BIOS and select CDROM as your primary booting device. Now follow the below-mentioned steps:

1. Insert your Windows XP installation CD into the CDROM and reboot your PC.
2. Press any key to proceed with the boot from CD when you are prompted to do so.
3. When the Windows XP setup menu shows up, hit the “R” key to proceed with repairing Windows.
4. If there is only one Windows installed on your computer then hit the “1” key and proceed by pressing enter. If there are more than two Windows then hit the number which is associated (according to the screen you are viewing) to the Windows you want to repair. Usually, this is C:/Windows and associated with “1” but if that is not the case then you should simply press the number that corresponds with the windows you want to repair and proceed.
5. Now, you will see a screen that prompts you to enter your administrator password. Most people don’t have an admin password and in that case, you should simply hit enter and you’d be good to go. If you do have an administrator password, however, then you should type it in, hit enter, and proceed.
6. When the DOS prompt shows up, type in chkdsk/f and hit return.

If you see no improvement in solving Error 0x00000024, and the problem keeps persisting, then you should start over. But this time you should type sfc/scannow instead of chkdsk/f and hit return. There are a few other complex methods that you can try as well but this is the most recommended procedure as it is easier, quicker, and most likely to fix the error.[/vc_column_text][/vc_column][/vc_row]

If you are running the Windows Update service but decided to stop it but you encountered an error message instead that says, “The Windows Update service could not be stopped”, read on as this post will help you fix the problem. This kind of error appears when you use the Command Prompt to stop the Windows Update service, especially if you are using cmd without admin privileges. A lot of users reported that they were not able to disable the automatic Windows Update in Windows 10 using Command Prompt. The command used to stop the Windows Update service is the “net stop wuauserv” command. However, when some users executed this command, they got the error message. So if you are one of these users that can’t stop the Windows Update Service via Command Prompt, you can try to fix that using PID as well as checking the Service dependencies. For more details, follow the given options below.

Option 1 – Try to stop the Windows Update service via PID

In case you don’t know, each running service or process has its own unique ID or PID and you can find it in the Task Manager. You can use it to stop the Windows Update service. How? Refer to these steps:

• Tap the Ctrl + Shift + Esc keys to open the Task Manager.
• Next, go to the Services tab and look for the service named “wuauserv” and get its PID.
• After that, type “cmd” in the Windows Start search and right-click on Command Prompt from the search results and then select the “Run as administrator” option.
• After opening Command Prompt with admin privileges, execute this command: taskkill /f /pid <PID>

Note: You need to replace “<PID>” with the PID of the “wuauserv” service. For instance, the PID is 6676, then this is how the command should be “taskkill /f /pid 6676”.

• After you execute the command, you will this message on your screen, “SUCCESS: The process with PID 6676 has been terminated” which indicates that you have stopped the Windows Update service successfully.

Option 2 – Try to check the Service dependencies

Dependencies of a Windows Service in Windows 10 are when windows services depend on other services. Such is the case with the Windows Update service – it also depends on three different services such as the Remote Procedure Call or RPC service, DCOM Server Process Launcher, and the RPC Endpoint Mapper. Meaning to say, if two of these services are not working as expected, then the dependant service will also be affected. This could be the reason why the Windows Update service could not start.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter to open Windows Services.
• From the list of Services, look for the following services:
  • Remote Procedure Call (RPC) Service
  • DCOM Server Process Launcher
  • RPC Endpoint Mapper
• After you find these services, double click on each one of them and check whether the Startup type for all is set to Automatic and the Service status is set to Running or not.
• If the service status is not running, then click the Start button. Afterward, check if you can now run the Windows Update service.
