As you know, the Videos folder can be found under “This PC” by default on your Windows 10 computer. However, as per the reports of some users, there are a few occasions where it somehow gets replaced by the Documents folder. In other words, the Videos folders are replaced by a duplicated copy of the Documents folder. Out of the two Documents folder, one Document folder will contain all the usual files and subfolders while the second one is empty. Although when you click the Documents icon on your Desktop (if you have a shortcut), it will still take you to the right Documents folder.
To fix this particular issue and get the Videos folder back in the File Explorer, here are some potential fixes that should help.
Option 1 – Run System Restore
The first thing you can try to do to resolve the problem is to run System Restore. This can help you go back to the previous state of your computer before the issue with the Videos and Documents folder.
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.
Option 2 – Try to restore Defaults
The next thing you can do is to restore Defaults. How? Refer to these steps:
Open File Explorer and then right-click on any of the two Documents folders.
After that, select the Properties option from the context menu and switch to the Location tab and click on Find target.
Next, copy the address and paste it in the field above the “Find target” option, and then click the “Restore Default” button.
Option 3 – Try to change the Registry Path
Tap the Win + R keys to open the Run dialog box.
Then type “Regedit” in the field and tap Enter to open the Registry Editor.
Next, navigate to this registry path: HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerUser Shell Folders
After that, edit the path for {35286A68-3C57-41A1-BBB1-0EAE73d76C95} under the “User Shell Folders” key to match the path shown for My Videos: %USERPROFILE%Videos.
Once you’re done, open the folder under “This PC” that has the Documents icon and tap Shift + right-click in the folder background, and then select the “Open PowerShell window here” option to fix the naming of the Documents folder. The path should read: “C:users<UserName>Documents.
Next, execute this command: ri desktop.ini –force
The command you entered will delete the files and folders and so when added for Documents, it will get rid of the empty Documents folder.
Now all you that’s left to do is to find where the target location is going to be for both folders and check if anyone foes to the user name location.
Then delete the one which goes to the incorrect location.
One of the useful features that came with Windows 10 is the Mobile Hotspot although there’s a downside to it – it drains your battery faster especially if your Windows 10 device is running on battery. Another one of its flaws in the implementation of this feature is that it stays activated even when the connection is idle. In other words, it is still activated even if no devices are connected to it. As a result, it consumes battery life and affects it. There are also instances when it affects the performance of the network connection. At the time of writing, Microsoft hasn’t done anything about this dilemma yet so in the meantime, you can continue reading this post to resolve this issue on your Windows 10 device.
You can remedy this Mobile Hotspot issue by running a command in Windows PowerShell. To get started, follow the given instructions below.
Turn off Mobile Hotspot Automatically:
Step 1: The first thing you have to do is to copy the following command:
Step 2: After copying the command given above, open the Notepad app and paste the command you copied there and save it. And when saving it, select the “Save as” option and its File type as “All files”.
Step 3: After that, put “TurnOnTimer.bat” as the file’s name and save it on your Desktop.
Step 4: Once done, run the file you just created, and when a User Account Control or UAC prompt appears, just click on Yes.
Step 5: After you run the file, it will run a series of scripts in a command line which will turn off the Mobile Hotspot automatically when idle.
And that’s how you automatically turn off the Mobile Hotspot when your Windows 10 device is idle. On the other hand, if you want to undo the changes made, you can always do so using the steps provided below.
Turn on Mobile Hotspot:
Step 1: Copy and paste the following command in the Notepad app:
Step 2: After copying and pasting the command, save it as “TurnOffTimer.bat” on the Desktop.
Step 3: Once done, run the file like what you did earlier and select Yes when a UAC prompt pops up. This will run a series of scripts on a command line which will revert the changes back to their default state.
According to some reports, using RDP or Remote Desktop Protocol on recent versions of Windows 10 results in a black screen. One encounters this issue is when using the Remote Desktop Connection feature on Windows 10. The real causes of this black screen are either the display drivers or some misconfiguration with the Remote Desktop Connection utility.
In most cases, the Remote Desktop in Windows 10 will display a black screen and then disconnects afterward. To fix this kind of issue on your Remote Desktop, there are two suggestions you need to check out. First, you can try to disable the persistent bitmap caching, and then you can also try to update your display driver. Follow the given options below for more troubleshooting instructions.

As you know, the Taskbar is one of the integral parts of the Windows desktop and it has been there since the release of Windows 1.0 and up until now with Windows 10. Since then, Microsoft has been modifying the Taskbar with a new design which makes it a home for new features such as Windows Search, Task View, and many more. However, there are times when you may that the Taskbar has disappeared or has stopped responding. If you experience either one of these scenarios, read on as this post will walk you through what you can do to resolve the problem.
Here are some suggestions you can check out to resolve the issue with the Taskbar in Windows 10 but before you proceed, make sure that you create a System Restore point first. To do that, follow these steps:
In the Start search, type in “create a restore point” and click the entry “System Properties”.
Next, select the main system drive under Protection Settings and click on the Configure button.
After that, select the “Turn on system protection” option and then click on the Apply and OK buttons to save the changes made.
Once you’ve created a System Restore point, refer to the troubleshooting steps below to fix the Taskbar in Windows 10.
Option 1 – Try to restart the Explorer process
This may sound really basic but it actually is a proven method to fix the Taskbar issue. So if anything gets stuck on the system tray or the Taskbar, you can always fix it by restarting the explorer.exe. How? Refer to these steps:
First, right-click on the Taskbar and select the Task Manager.
After opening the Task Manager, go to the Processes tab and look for the process named “Windows Explorer”.
Then right-click on that process and select the option to Restart. Afterward, you should now be seeing the Taskbar as this will reload the whole Windows Shell.
Option 2 – Unhide the Taskbar using the Settings app
It is possible that the Taskbar could be hidden so you can try to unhide it using the Settings app.
Tap the Win + I keys to open Settings.
After that, go to Personalization > Taskbar.
From the main section, make sure that the “Automatically hide the task in desktop mode” is toggled to the off position. However, if it’s already off then proceed to the next options below.
Option 3 – Make sure that you are not in Tablet Mode
Since Windows 10 is designed to work on both desktop and mobile devices, it could be that your computer has slipped into Tablet Mode which explains why you’re not seeing the Taskbar. To check if your computer is really in Tablet Mode, follow these steps:
Go to the Start menu and select Settings.
Next, select the System setting and from the left pane select the Tablet Mode.
From there, make sure that the buttons next to the options given below are set to the off position:

Tap the Win + P keys to open the Windows Projection settings.
Next, make sure that you select the “PC screen only” option and then check if your Taskbar has now appeared or not.
As you know, the Office Language Packs need to be installed right after installing Office. It also has to be on the correct version of Office so if any of these conditions are not met, you will most likely get error codes 30053-4 or 30053-39 when you install a language pack in Microsoft Office. If you are currently facing this error, read on as this post will help you fix the problem. Here’s the full context of the error message:
“Something went wrong, Sorry, installation cannot continue because no compatible office products are detected.”
When you have to work on two different languages, that’s where the language packs come in handy. You might have to work on one language but when it comes to proofreading or help, you need another language. Note that some language accessory packs offer partial localization which is why some parts of the Office might show the default language.
If you are using Office 365 or Office 2019, 2016, 2013, or 2010, you need to go to the language accessory pack page from office.com and select your language. Once you see the download link, click on it to start downloading the pack. It includes the display in the chosen language, proofing tools for the selected language, as well as the Help in the selected language. Once the installation is complete, follow each one of the given options below to configure the language accessory pack properly.
Option 1 – Select Editing and Proofing language
You need to open any Office program and navigate to File > Options > Language.
From there, you need to make sure that the language you want to use is in the list under the Choose Editing Languages section.
After that, you can add or remove the language that Office uses for editing and proofing tools.
Option 2 – Configure the Display and Help languages
In this option, you can change the default display and help languages for all the Office applications so whatever you choose will be used for all the buttons, menus, and support of all the programs. After you select the language, restart all the Office applications to apply the changes made successfully.
On the other hand, if you are using Office volume license versions, note that only an administrator account can install this if you are using the Volume License version of Microsoft Office 2016. You have to download the ISO image of the language packs, language interface packs, and the proofing tools from the VLSC or Volume Licensing Service Center. This process can be quite complicated so you might have to go to the docs.microsoft.com page to be guided accordingly. After you installed everything correctly, the error code 30053-4 or 30053-39 should now be fixed.
It really sucks when you can’t fully enjoy the newest version of your favorite OS.
Windows 11 is still relatively fresh and consequently has some annoying little bugs that really ruin our experience. The good news is that you’re not alone and most of them are easy to fix.
Here are 5 commonly reported Windows 11 issues and what you can do to get rid of them.
1. Windows 11 audio problems
One of the absolute most irritating things in the world is struggling with the sound on your computer. Windows 11 users have reported facing the issue of low or no sound. If you’re currently experiencing the same frustration, you can be relieved. Chances are fixing it will only take a few minutes.
The first thing to check would be whether you accidentally muted your device by pressing the mute button on your keyboard. Yes, we know it sounds a lot like the old “have you tried turning it off and on again?” But it’s important to leave no stone unturned, and the most obvious things are usually the ones we easily overlook.
Moreover, if you have several audio output sources, check whether the right one is selected. You can do this via the Action Center or through Settings. If you want to use the same source every time, we also recommend you set it as the default one.
It’s also important to have a good, up-to-date audio driver. More often than not, this will be the true cause of your audio struggles. Make sure to update your driver, and if that doesn’t work out, you can always un- and reinstall it or install a different one.
Lastly, if all attempts remain unsuccessful, run the audio troubleshooter to figure out what’s actually going wrong.
2. Unable to find files
Such a powerful new operating system, yet it can’t seem to do the simplest thing imaginable? The File Explorer not responding on Windows 11 is one of the most frustrating and most common problems with Microsoft’s newest iteration of its awesome OS.
However, 9/10 times it can be fixed by simply restarting your PC. You could also try killing the Windows Explorer process in the Task Manager and then rerunning it.
If these don’t help, check whether there are any pending Windows 11 updates. A single missing update can compromise your PC’s functionality, so always make sure to install them all on time.
Should none of that work, then there are other ways to solve the File Explorer problem. However, then the issue is probably a bit deeper and it’s no longer in the ‘easy fix’ territory.
3. Start menu not working
Just like the File Explorer, the Start menu is a fundamental element of your OS. So, it’s only natural that its malfunction grinds your gears. It may be more customizable than on previous Windows versions, but it doesn’t always work smoothly.
If you’re facing the so-called Start menu critical error, there are a few things this could be caused by. Usually it means you turned off your system while an important update was still being installed, there is a corrupt file on your PC, or Windows forcefully stopped a program.
Whatever the reason, the solution should be pretty simple. Try the basic steps: restarting your File Explorer (like we explained above) and signing out and back into your account. If that doesn’t do anything, you may want to try uninstalling third-party start menu apps (if you have any), since they can interfere with your default programs’ functionality.
Now, those are the easy fixes. If you get nowhere with them, you might need to identify the root cause and search for more complex solutions than that.
4. Snipping tool not working
Our beloved screenshot tool was introduced with Windows 10 and Microsoft decided to keep it. However, you were probably just as disappointed as us when you tried to run it and failed.
Normally, this can be fixed by installing the latest Out-of-band (OOB) update, or even pending updates in general. Even if your system appears to be up-to-date, run the checker just in case.
Another cool thing Windows 11 lets you do is ‘Repair’ and ‘Reset’, which is the easiest way to troubleshoot your Snipping tool. If this fails, you can also try the good old un- and reinstall method. Simply uninstall the tool through the Control Panel and reinstall it from the Microsoft Store.
Furthermore, in the case of an upgrade from Windows 10 to 11, it may be that the old Snipping tool version is interfering with the launch of the new one. If you don’t care that much about the additional options available with the enhanced screenshot tool, you can use the old version instead.
Simply go to your C Drive, find the Windows.old folder, search for the tool and open it from there. Make sure to pin it to your taskbar as well, if you know you’re going to use it often.
5. Can’t install the latest update
The latest Windows 11 version, 22H2, has brought tons of enhancements to our dearest operating system. Unfortunately, a lot of users still haven’t had the opportunity to experience it. A mere update of your OS version should be the one thing that goes smoothly, but sometimes that’s not the case.
Failure to install 22H2 can be caused by a few things. Most commonly, the issue is caused by lack of storage space or corrupted files, but there could be other culprits.
There are a couple of things you could try. For example, it’s crucial that your drivers be up-to-date and some important services be enabled. These are: Windows Modules Installer, Background Intelligent Transfer Service, Cryptographic Service, Windows Update services.
To enable them, search ‘Services’, find the service you need and right-click on it. Open ‘Properties’ and select the startup type ‘Automatic’.
It may also be necessary to unplug all peripherals that aren’t crucial and disable third-party antivirus tools until after the update is finished.
Ultimately, you can run the Windows Update troubleshooter to detect and fix other possible issues.
Summary
Tiny bugs like these are nothing out of the ordinary. That said, we still all hate when they happen.
Hopefully some of our solutions have helped you to a smoother Windows 11 experience. But if you’re still struggling, feel free to reach out to us. We’d be happy to help!

0x Referenced Memory at 0x is an error code that occurs when the random memory addresses conflict.
This error causes running programs or browsers to crash. Referenced memory at error code is considered as a service violation error. It is displayed as the following:
“The instruction at 0xf77041d24 referenced memory at 0×00000000. The memory could not be read.”
Solution
Error Causes
The ‘referenced memory at’ errors is either triggered by:
Hardware failure
Problems with the RAM and the registry
Hardware failure may result if the driver is not installed properly. The problems in the RAM indicate registry issues that occur due to data overload in the hard disk and poor PC maintenance.
The registry saves all the information and activities you perform on your system on the hard disk.
This includes the junk files, temporary files, invalid registry entries, and files of both installed and uninstalled programs. These files accumulate and take over a lot of RAM space.
Also, the referenced memory at error can be considered to be a form of memory leak where unknown third-party software can take up the memory space that has been reserved for a particular program.
For example, if you have toolbars and add-ons installed in your browser, it can also lead to invalid registry storage in the registry.
If you don’t clean the registry, these unnecessary files can overload your data and lead to hard disk/RAM damage and corruption triggering obscure error messages like referenced memory at error.
Further Information and Manual Repair
Referenced memory is a critical error; if not resolved it can lead to serious PC damages like a system failure. To avoid this, it is advisable to fix it right away.
Here are a couple of ways to repair this issue on your system:
Cause: Hardware Failure
Solution: If the referenced memory at error is generated due to hardware failure then to resolve this error you must reinstall the driver that has caused the error to appear.
Let’s say if the error pops up because of the printer driver, reinstall it. For re-installation of the driver, simply go to the control panel and click on the Device Manager option.
Once you click it you will see a detailed page with a list of devices.
Now click on the printer (the problematic driver in this situation) to reinstall the driver software. Double click on it to open the properties dialog box and then click the driver tab and update the driver. Once you have updated the driver, try using the printer. Check if it works.
If it works and the referenced memory at the error code does not appear on the screen, this means the problem was with the hardware. However, if the error still pops up then this means the problem is deeper. It’s related to the registry.
Cause: Problems with the RAM and the registry
Solution: If the problem is with the RAM and the registry, then it is advisable to download Restoro.
Restoro is a new, next-generation, and highly functional registry cleaner.
It detects and removes all the registry issues, unnecessary and obsolete files saved in the hard disk taking up a lot of RAM space. It clears the RAM and cleans up the disk.

C00002lA Fatal System Error is a blue screen of death error that may occur when you start your Windows NT 4.0 based computer. This error causes the screen to turn blue and the system also shuts down.
The stop C000021A error message is displayed in the following format:
Stop c000021a {Fatal System Error} The session manager initialization system process terminated unexpectedly with a status of 0xc0000017 (0x00000000, 0x0000000) The system has been shut down.
Error Causes
The stop C000021A error occurs when either Crsrss.exe or Winlogon.exe fails. When the Windows NT kernel identifies that either of these processes has failed, it stops and the error code stop C000021A appears on the computer screen.
Here are some of the underlying causes for the stop C0000021A error:
The incompatible third-party program
Hard disk issues
Service pack installation has failed
Mismatched system files have been installed
Bad and invalid registry keys
Further Information and Manual Repair
To resolve the stop C000021A Fatal System Error on your PC try the following solutions:
Remove Incompatible Third Party Programs
If the error occurred after you recently installed a new program, then it is advisable to remove that program. The error occurs due to the incompatibility of the program.
To remove the program go to the start menu and click on the control panel. Now click on Add/Remove Program tab and double click on the program name that you recently installed and remove it from the list.
Once removed, not reboot your PC. Reinstall a compatible program and run it. It is most likely to resolve the issue. However, if the stop C000021A error still occurs, then it means the problem is critical. It is related to the registry.
Repair and Restore the Registry
This procedure is slightly long and tricky.
To try it, you need to be technically sound. Here’s what you have to do: first create a parallel installation of Windows NT.
Start your PC to the parallel installation and then open the Registry Editor. On the Registry Editor’s Windows menu click HKEY_LOCAL_MACHINE on Local Machine and then click Load Hive.
Now type the path %systemroot%system32configsystem into the System hive of the prior installation. Then click open. Here you will be prompted to enter the name of the key, type TEST.
Note the setting for the current DWord value in the preceding registry key. This is 0x1 and is denoted by CURRENT:Reg_Dword: 0x1.
This value indicated that the Current Control Set for your original Windows NT installation corresponds to ControlSet001 in this window. Now if the value is 2, it indicated that the Current Control Set corresponds to ControlSet002.
Now locate the following registry key:
HKEY_LOCAL_MACHINETESTControlSetXXXControlSession Manager. XXX is the Current Control Set Value. And delete any pending file rename operation entries. Then click TEST hive and then click Unload Hive. After that again repeat the process, open the registry menu and click load hive, here type the path %systemroot%system32configSoftware to the Software hive of the prior installation and then click open.
Now you type TEST 2 when you are prompted for the name of the key. Remove any pending file rename operations entries in the following registry keys:
HKEY_LOCAL_MACHINETEST2MicrosoftWindowsCurrentVersionRunOnceHKEY_LOCAL_MACHINETEST2MicrosoftWindowsCurrentVersionRunOnceEx
Now click TEST2 hive and then click unload hive. Quit the Registry Editor and then restart your original installation.
This will resolve the stop C000021A error.
Two monitor systems are not such a rarity like they were just a couple of years ago. More and more people are finding out the benefits of having 2 screens instead of one no matter if you play games or do serious work. So how technology has moved forward and new norms so have Windows and we can now set different wallpapers to different screens very easy, a task which was very difficult in the past.
Go to the Personalization option in the Control Panel.
Right-click on your home screen and select the Personalize option from the menu.
In the new window, you can browse for images you wish to set as wallpaper on both of your monitors. This way, the images would be preloaded in the “Choose your picture” option.
Right-click on the image. Doing this will open a new menu that will allow you to set wallpapers for each screen. There is also another option called “Choose a fit” which gives you the option to select the fit of the wallpaper.
Choose one wallpaper for “monitor 1” and a different wallpaper for “monitor 2.” You will now see your dual-screen setup customized with two different wallpapers.
