Hello and welcome to errortools another tutorial which aims to make your computer life easier and more relaxed. This time we will be talking about how to switch sound output devices in Windows 10 in a matter of seconds between Headphones and external speakers, Between 2 different speakers, or any other audio output device in general. Windows 10 with its updates has really gone from OK to one of the greats, little hacks and shortcuts which every update has introduced have really made life easier. Now, your typical switching from one audio output device to another can be accomplished with your standard go to settings, go to devices, choose audio, pick one which you prefer and click on OK. This way altho nothing wrong with it is a little slow and if you need to switch your output devices several times in a single day often it can be time-consuming as well. Lucky for you we have a quick solution for you.

Switching guide

All right, now in order to be able to actually switch between your audio output devices make sure that all of them are working and that they are plugged in. For example, make sure that both of your headphones and speakers are turned ON and plugged in. Once you have confirmed that everything is in working order:

1. Click with a left mouse button on a speaker icon located on the right part of your taskbar next to the clock
2. Click on the small up arrow on the right next to your current audio output device.
3. The list will open, choose, and left click with the mouse button on your choice.

And that's it, you have changed your default audio output device in a matter of seconds. The good thing about this method is that Windows will remember output audio levels for each device.

Potential issue

If by any chance when switching your audio devices this way freezes volume control just go to the task manager and restart Windows Explorer. To restart Windows explorer:

1. Press CTRL + ESC to open task manager
2. Right-click on Windows Explorer
3. Left-click on restart

Each time you open an application inside your Windows 11 operating system, it is opened with standard privileges. Now, please note that your account privileges and application privileges are two different things, you might be the administrator of the system but when you open the app, it still opens with standard privilege. Most of the time running applications with typical settings is fine but from time to time we might have some applications that will require running with administrator privilege in order to work properly. In this case, it is very easy to do it, you just right-click and choose run as administrator. Although a very easy solution, it can be quite annoying if running the app is on a daily basis or even more times per day. If this is the case then right-clicking and choosing to run as administrator can be a daunting task, sometimes you can even forget to run it like this in heat of work and some unforeseen consequences might occur. Luckily there is an easy hack so you can open the chosen application each time as an administrator with a simple double click each time.

Setting application to run as administrator always

1. Locate application executable file
2. Right-click on in and choose properties
3. Click on the Compatibility tab
4. Check the box next to Run this Program as an Administrator
5. Click on Apply
6. Click on OK

From now on each time you open an application normally with a double click, it will be opened as administrator privileges.

A lot of Windows 10 users have reported recently that their computers are frequently crashing with a Blue Screen error with an error code “VIDEO_DXGKRNL_FATAL_ERROR”. This kind of Stop error appears not so often and its bug check value of 0x00000113 is an indication that there is some violation in the Microsoft DirectX graphics kernel subsystem. This error also occurs when there is a corrupted driver that interferes with the GPU’s normal functionality. According to some security experts, this kind of error is reported to only occur in Windows 10 PCs. Users started getting this error right after a large Windows Update. The cause of this error might have something to do with a violation in the DirectX graphics kernel subsystem where there could be a bad DirectX install or some corrupted Dynamic Link Library or DLL. Aside from that, the error might also be caused by the Nvidia driver which might have crashed or it could also be that there is an intermittent power supply. Moreover, an outdated BIOS as well as a third-party security program might be the ones behind this Blue Screen error. Whichever the case may be, you need to fix the VIDEO_DXGKRNL_FATAL_ERROR BSOD error by following the instructions given below carefully.

Option 1 – Try checking if the NVIDIA graphics card is enabled and update it as well

Although the problem is quite massive, the fix could be as simple as enabling the NVIDIA graphics card if it turns out to be disabled. There might be some strange reason why your graphics card disables itself. Thus, the best and first option you can try is to check if the NVIDIA graphics card is enabled or not. To do so, follow these steps:

• Tap the Win + R keys to open the Run dialog box.
• Then type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
• After opening the Device Manager, look for the Nvidia graphics card option among the list of device drivers. Once you found it, check if it is enabled or not. If it’s not enabled, you should see a gray arrow pointing downwards. Right-click on the card and select Enabled.
• Next, right-click on the graphics card once more and click on the Update Driver Software option and then click on the “Search automatically for updated driver software” option.

Option 2 – Update or uninstall third-party security program

As mentioned, the VIDEO_DXGKRNL_FATAL_ERROR Blue Screen error might be caused by a third-party security program that’s installed on your computer. So you have to either update it or uninstall it to resolve the issue.

Option 3 – Check the power supply for any inconsistency

The Blue Screen error might also be caused by an intermittent power supply. If there is any intermittent changes between the main supply and the battery power, it might lead to bad contact on your supply to the charger and thus, causes the VIDEO_DXGKRNL_FATAL_ERROR Stop error to appear. So to check if this scenario is applicable to you, you have to monitor your computer for any frequent changes between the power supply and the battery power. If you see that the supply is displaying power On and Off, see if the same goes when the power supply is disconnected. However, if it does not occur, you might have to purchase a new power adapter cable and replace the one that you have right now.

Option 4 – Reinstall the Graphics card drivers

• Tap Win + R to open Run then type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
• From there, look for the Display adapters and uninstall each one of the graphics card drivers by right-clicking on them and selecting the Uninstall device option.
• After uninstalling the graphics card drivers, close the Device Manager and tap Win + R to open Run once again.
• After that, type “appwiz.cpl” in the field and hit Enter to open Programs & Features in the Control Panel.
• Next, look for any program that’s related to your GPU manufacturers like Nvidia, AMD, or Intel. Right-click on any GPU-related entry and click on Uninstall to uninstall them and then follow the next on-screen instructions that appear afterward.
• Now restart your computer.
• Once your computer has restarted, go to the GPU manufacturer’s website and download the latest driver version for your graphics card model and then install it.
• Restart your computer once again. That should fix the problem.

Option 5 – Try checking if there are any BIOS updates available for your PC

Updating the BIOS may help you resolve the BSOD 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.

Option 6 – Perform a System Restore

Performing a System Restore on your computer can also help you fix the VIDEO_DXGKRNL_FATAL_ERROR Blue Screen of Death error. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• 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.

A lot of users connect to the internet are using VPN on their Windows 10 computers which means that their regions could be different from the actual region of their Windows 10 computers. Thus, if you are facing some issues in updating your computer in this kind of environment, specifically the Windows Update error 0x800F0922, you need to follow the tips given in this guide to help you resolve the issue. When you encounter this kind of Windows Update error, you might see either of the following error messages on your screen:

“Windows could not search for updates, Code 0x800F0922 Windows Update encountered an unknown error” Or: “Windows failed to install the update with error 0x800F0922”

This issue might be caused by two possible reasons such as:

1. VPN issues
2. Not enough space on the System Reserved partition

To resolve the problem, here are some tips that might help:

Option 1 – Try disabling the VPN

As mentioned, if you are using VPN, this could be the reason why you’re getting the Windows Update error 0x800F0922 so the most obvious thing to do is for you to turn off the VPN and try to run the Windows Update once more. And if you use a VPN software that works using their software, you can just completely exit or log-off from its account. On the other hand, if you are using a built-in Windows 10 VPN, you can simply turn it off or delete all the settings you have created there. Although it’s understandable that you might have to use a VPN connection to connect to the work network, you really have to disable it at least until the Windows Update is no longer stuck in the error 0x800F0922. It would be best if you do this when you are not working.

Option 2 – Try to free up space in the System Reserved partition

The System Reserved partition is a part of the hard disk created when Windows is first installed on it. It is where the Boot Configuration Database, Boot Manager Code, Windows Recovery Environment, and the reserves space for the startup files are stored. And as mentioned early on, the error might be due to some insufficient space in the System Reserved partition so the next thing you can do is to increase the space in this partition. Note that it is a complex process so you need to make sure that you have made backups to all your data on the computer. So if ever something goes out of hand, at least you have copies of your important files in case you aren’t able to boot into the system at all.

One of the most basic and commonly used features in the Windows operating system is the copy and paste feature that helps users accomplish tasks in a faster and easier way. However, if you notice that it’s not working properly for some reason, then this post might be of help as it will provide you with options you can check out to resolve the problem. You can encounter this kind of problem with the copy and paste feature if some system files are corrupted or if there’s some third-party application or process that interferes with this function. Worry not though for there are some options you can check out to fix this. You can try to restart the rdpclip.exe process or the explorer.exe process. You could also try to reinstall the program where you encountered the issue with the Copy and Paste function. In addition, you could try clearing the clipboard history or run the built-in tools like the DISM tool and SFC scan. You could also troubleshoot the problem in a Clean Boot State or use the Refresh Windows tool. For more information, refer to each one of the options below.

Option 1 – Try to restart the rdpclip.exe and the explorer.exe processes

The first thing you can do to resolve the problem is to restart certain processes namely, the rdpclip.exe process and the explorer.exe process via Task Manager.

• First, right-click on your Taskbar and select the Task Manager.
• Next, look for the rdpclip.exe process and right-click on it, and select the End process option.
• After that, click on the File tab > Run new task and then type “rdpclip.exe” and tap Enter.
• This should help fix the problem. If not, you could also try to restart the explorer.exe process – just look for the explorer.exe process in the Task Manager and right-click on it, and then select the Restart option.

Option 2 – Try reinstalling the concerned program

If you only experience this issue on a particular program, you might want to uninstall this program and install it back again, and then see if it fixed the problem or not.

Option 3 – Try to clear the clipboard history

You could also try clearing the clipboard history as it has been known to help in fixing this kind of issue. You can clear the clipboard history using the command line.

• Tap the Win + R keys to launch the Run dialog box and type “cmd” in the field and hit Enter to open Command Prompt.
• Next, execute this command: echo off | clip
• After that, check if the Copy and Paste function is now working properly or not.

Option 4 – Try running the DISM tool

You can run the DISM tool as well to help fix the “Tile Database is corrupt” 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
  • DISM.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.
• Once it’s done, check if it was able to fix the corrupted Start Menu or not.

Option 5 – Try to run System File Checker or SFC scan

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow and hit Enter.
• Once done, restart your computer.

Option 6 – Restart your computer in a Clean Boot State

If a third party program like antivirus is the one that’s causing the problem, you can try to put your computer in a Clean Boot State to isolate the issue by following these steps:

• Log onto your PC as an administrator.
• Type in msconfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• Now try to connect your device or copy the files to your external device again and check if the problem with the Copy and Paste function is fixed.

What is Search.schooldozer.com? And how does it function?

Search.schooldozer.com is a browser extension that functions as a search engine. It is developed and maintained by “Schooldozer”. It claims to improve users’ browsing experience by providing them with improved search results. However, it does not really do the things it claims to do. In fact, they’re quite the opposite ones – instead of improving the browsing experience, it makes users’ browsing experience unsafe and full of sponsored content. This is in contrast to what it states in its Privacy Policy:

“Install applications the easy way and without the hassle, using the Schooldozer downloader. The Schooldozer platform stems from years of experience with installing applications, resulting in a highly optimized process, yielding faster downloads, better user experience, and more successful installations.”

Running the Windows Setup does not always go smoothly as you could encounter some errors along the way. One of these errors is the “Something happened, Setup has failed to determine supported install choices” error. The only given option in such cases is to click the Close button and exit the setup. This kind of error in Windows setup can occur when you try to downgrade to the previous version of Windows using the built-in mechanism. This error could be caused by a corrupted image or it is also possible that the set of files are incomplete. Aside from that, it could also be due to compatibility issues or that the module used to downgrade the Windows operating system is not configured properly. To fix this error, you have to run the Windows Setup program in compatibility mode so that you can downgrade Windows. You could also use the image for the lower version of Windows that’s available on the official site of Microsoft. But before you do any of these, make sure that you’re logged in as an administrator. To fix the “Something happened, Setup has failed to determine supported install choices” error, follow the given options below sequentially.

Option 1 – Try to run the Installer of the downgraded version in Compatibility Mode

This is the first thing you can try to resolve the issue instead of going right ahead on making a bootable device. So if you are downgrading Windows, you can try to run the installer in the compatibility mode for that specific Windows version.

• 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 either Windows 7 or Windows 8.
• 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 “Setup has failed to determine supported install choices” error 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 – Run the DISM tool

You can run the DISM tool as well to help fix the error code 0x80244022 during Windows Update. 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 4 – Try using the image from the official site of Microsoft

If none of the options given above worked, you can try to use the image from Microsoft’s official site. This would help, especially if the error is caused by a corrupted image or image folder with incomplete files.
