Videos folder missing from File Explorer

If the Sleep option is missing from the Power Menu then this could be caused by the power settings, local group policy configuration, etc. in your computer. Based on the reports of users who experience the same problem, the issue occurred after they’ve updated or upgraded their Windows 10 computers. As you know, the sleep mode is quite useful in certain cases and is utilized by most users. If you put your computer in sleep mode, it actually minimizes the power usage of your computer while at the same time keeps your current session running. So if sleep mode is suddenly missing, then that could be a problem but worry not for this post will give you possible fixes to resolve the issue. Make sure to follow each one of them carefully to achieve good results.

Option 1 – Check the Power settings

As mentioned, one of the reasons why the Sleep option is missing could be the power settings in your computer. To check this possibility, make sure that you’ve enabled the sleep mode in the Power options setting window. How? Refer to these steps:

• First, go to the Start menu, and from there open Control Panel.
• Next, set the View by Large icons and select the Power Options.
• After that, click on the “Choose what the power buttons do” option on the left-hand side.
• Then click on the “Change settings that are currently unavailable” option and make sure that Sleep is checked under the Shutdown settings.
• Afterward, click on Save changes.

Option 2 – Modify the Local Group Policy

If the Power setting isn’t the cause of the problem, then you might want to check the Local Group Policy and modify it. There is a dedicated policy for showing the sleep option in the power menu and if this policy is disabled, then it’s no wonder why you don’t see the sleep option in the power menu. To change this policy, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “gpedit.msc” in the field and hit Enter to open the Group Policy Editor.
• Next, navigate to this path: Computer Configuration -> Administrative Templates -> Windows Components -> File Explorer
• Look for the “Show sleep in the power options menu” option from the right-hand side pane and double click on it.
• Now change it to Enabled and click on the Apply and OK buttons to save the changes made and restart your computer.

Option 3 – Try to turn on Standby

Standby, also known as InstantGo, is a feature in Windows 8 and 10 that allows users to maintain network connectivity after a computer has been put into sleep mode. Thus, if this feature is disabled, it can cause the Sleep option to disappear from the power menu. To turn it on, follow these steps:

• Tap the Win + R keys to open Run.
• And type “Regedit” in the field and tap Enter to open the Registry Editor.
• Next, navigate to this path: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlPower
• From this path, look for the “CsEnabled” key on the right-hand side of the pane and double-click on it.
• Set its value to “1” and click OK to save the changes made.
• Now reboot your PC.

Note: If you were not able to find the CsEnabled key, then this indicates that your computer does not support the Standby feature. And if that’s the case, proceed to the next given option below.

Option 4 – Try to install a Video Card driver

On the other hand, some users reported that the problem was caused by the video card driver. And if your computer lacks the video adapter driver, it can also cause the same problem. Windows 10 typically install the video card driver on its own, however, there are rare cases when it doesn’t which is why you have to do it yourself manually. All you have to do is go to your manufacturer’s website and look for the video card driver, download it and then install it. Once you’ve installed the video card driver, reboot your computer and check if it has fixed the problem.

Recently Logitech has released a new line of ergonomic mouse products on market, strangely shaped and lifted on a vertical axis Logitech claims that these devices will fix your issues and ease your hand pains for prolonged use of the computer.

The first time I saw this mouse I was not really impressed with its looks and somehow I thought it will not feel good. This all changed when I actually started using it, surprisingly altho strange in looks it does feel much more natural and much less stressful on hand. Also, it felt like I have used it before, personally, I did not need any adjustment period in order to use it fully.

All of that being said I will admit that using it for gaming is still not an option for me, someone might find it ok, especially if they play some games that do not need to be responsive like strategies or similar but for RTS and FPS I will still stick to the typically shaped mouse. This might be just a habit for me but somehow I feel more responsive with the typical mouse, but for anything else, this is the mouse that will keep your hands stress-free.

Now in order to get the mouse to be really recommended it needs to have some good technical specifications as well, looks are not all. The less important detail is that the mouse comes in 3 different colors: Black, white and pink, and its technical specifications are:

Specs & Details

Dimensions

Height: 71 mmWidth: 70 mmDepth: 108 mmWeight: 125 g

Technical Specifications

Sensor technology

• Sensor type: Logitech Advanced Optical Tracking
• Dpi range: 400-4000 dpi (Fully adjustable with 100DPI increments)

Personally, I would recommend this mouse for anyone who does work in front of the computer during the whole workday since it really does loosen grip and strain on hands.

Hello everyone, in today's tips and tricks we will focus on providing you with various solutions on how to solve the Device not migrated error that appears after the Windows update has been performed. Sometimes sadly updates to our operating systems can introduce us to various issues that look scary but in reality, they are solvable and not so scary at all. After all who would not find this message concerning, especially when it happens in the middle of work. The first thing that would pop into my mind is that I have lost tons of work and that something in my hardware has gone very wrong and it is dead. Luckily that is not the case and this error means that due to Windows update drivers were not properly transferred due to some compatibility issues, maybe it was a corrupt update file, etc. Of course, the reason could be hardware malfunction as well, but if everything was working fine before the update, it is a software issue, and I must say it is a common one and fixable. Please keep reading this guide in order to fix the Device not migrated error.

1. Update the Driver

   You should always try this first, if the device is not recognizable, try updating its driver and see if the problem vanishes. In order to update the driver, we will need first to locate which device has not been migrated properly, we will do this with help of a search engine on the internet like google for example. So open your browser of choice, go to a search engine (google for example) and type in the search box first line from your error message, yes, that scary one. You will be given which device has malfunctioned and was not migrated properly, now we will locate the device and update its drivers. To do this press WINDOWS + X on your keyboard to bring up Windows secret menu and choose device manager. Find device inside device manager, right-click on it, and choose properties. Go to the events tab and make sure that the device has migration issues. You have now 3 options for updating the driver, you can do it manually, automatically, or with the driver installer. We will cover all 3 options so you choose which one best suits you. OPTION 1: Manually. Close the Properties tab, go to the device manufacturer website and download the latest driver, if there are no drivers there, the only executable installer for the device skip this step and try the other 2. After you have downloaded the driver package from the website, right-click on the device and choose update driver. Now navigate to the folder where you have downloaded your driver package and update the driver. Reboot your system. OPTION 2: Automatic update. Close the Properties tab, right-click on the device and choose to uninstall. Once the device is uninstalled, restart your system, and Windows will automatically search and install the latest driver for the device. OPTION 3: Via driver installer. If you have downloaded .EXE or executable driver installer from device manufacturers web site try installing it, if the installation fails, try using compatibility mode for the installer. Navigate where the installer is located, right-click on it, and choose properties. Go to compatibility TAB and try installing it with administrator privileges in Windows 8 mode. Reboot your system after this step. This should solve the issues, however, if the issue still persists, follow the next steps.

2. Verify the Corrupted System Files

   Press WINDOWS + X on the keyboard to open the hidden system menu and choose Command prompt (administrator) In the command prompt type in: sfc /scannow and press ENTER. The scanning process and repair of files will take around 15 min. Leave it to finish completely, do not restart, work on the computer or shut it down while the process is active, and only after it is finished reboot your system.

3. Update Windows.

   If your Windows is not updated sometimes this issue can be resolved by updating it on the latest version. Click on start and then on settings. Once the settings screen is opened, find and click on Update and Security. Go to the Windows update tab and click on DOWNLOAD or click on check for updates for the latest Windows fix.

4. Reset BIOS to factory settings.

   Sometimes BIOS not being properly configured can cause issues in Windows itself and prevent it from detecting PnP devices thus creating this error. Restoring BIOS back to the factory setting can help. Turn off your computer and turn it back on. Press delete, f12, f11, or any other key which will take you to BIOS (default key is delete but sometimes manufacturers map this to another one. Once your screen turns ON you will see in the bottom message which key needs to be pressed in order to enter BIOS). Sadly since every BIOS could be different we can not cover step by step guide for each but you need to find the option where you load BIOS defaults, click on it save, and exit. Your computer will restart and boot into Windows, check to see if the problem still persists.

5. Update BIOS

   BIOS can cause issues with certain PnP devices when the newest Windows update is rolled. If reverting BIOS to the factory setting has not been successful try update. Go to your motherboard manufacturer website, find the update and read step by step guide there since updating BIOS differs from version to version and from manufacturer to manufacturer. After the update is done, restart the computer and hopefully, the error is gone.

6. Perform a System Restore

   If everything else fails, perform a system restore to get Windows back into the state before the update was installed and when everything was working fine. Press WINDOWS + R on the keyboard to open the run dialog. In the run dialog, type control panel and press enter to enter control panel, locate recovery and click on it. Inside the recovery screen click on Open System Restore. Choose a date when everything was working in order, the best bet is the date before Windows update and roll it back. Click on date, and then on next.

Windows Updates are checked for their validity every time they are downloaded from Microsoft servers just like how browsers check websites for a valid certificate. And so if you got an error message saying, “ Some update files aren’t signed correctly, error code 0x800b0109 ” while trying to update your computer, it indicates that the Windows service was unable to verify the validity of the Windows Update. To fix this error, you can try out the options prepared in this post.

Option 1 – Reboot your computer and try again

Save your work and reboot your computer and then try checking for updates again. In some cases, all you need is a restart to fix errors like error code 0x800b0109.

Option 2 – Try to update Windows after an hour or so

There are times when the issue is from Microsoft’s end. It could be that there’s some issue with Microsoft’s server so it would be better if you give it an hour or so before trying to run Windows Update again.

Option 3 – Try running 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 0x8007001E. 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.

Option 4 – Delete the contents in the Temporary folder

Error Code 0x8024001b- What is it?

At its most basic level, Error Code 0x8024001b is an error that can cause problems with the installation and updates of software and operating system updates. The most common version of this error appears in Windows 10, but a similar error with a matching code number has been present in previous versions of the operating system, back through Windows 7.

Common symptoms include:

• Programs freezing or locking up during use
• The appearance of an error message regarding installation difficulties
• Computer shutting down or freezing during operation
• Difficulty in running multiple programs at the same time

Solution

Error Causes

There are two main causes for Error Code 0x8024001b, both of which are fairly simple:  Updates needed for the Windows Update tool itself and software that causes Windows Update to fail during installations through conflicts in system files. While these may seem like technical issues, these problems are actually easily resolved with a few simple steps. The average user can use the methods listed below to fix the problems on their own.

Further Information and Manual Repair

For users who want to address Error Code 0x8024001b for themselves, the steps below can be followed to address the two primary causes for the error. If you have difficulty in completing these steps or are not confident in your computing skills and ability to follow the listed steps, contact a Windows repair technician.

Here are the top methods to resolve Error Code 0x8024001b on your own:

Method One:  Check for Updates to Windows Update

In some cases, the Windows Update tool may need an update for itself. When you attempt to run updates or install wizards for other software, it can cause conflicts with the Windows Update process, slowing down your computer or causing it to freeze.

If you are attempting to run multiple installations or updates at the same time, it may also cause Error Code 0x8024001b to arise on your computer.

To resolve this issue, close out all programs, with the exception of the Windows Update tool. Within the tool, select “Check for Updates” and install any updates that are needed. When finished, you should restart your computer to ensure that all updates have been fully applied before attempting any other installations or updates.

Method Two:  Uninstall Conflicting Software

Another problem that can cause Error Code 0x8024001b is the presence of conflicting software. If Error Code 0x8024001b has only recently appeared on your computer, consider removing any software that has been added to your computer, running the Windows Update process, and restarting your computer before attempting to reinstall the problem software.

With any method that you use, it is important to remember to keep your Windows Updates current at all times. This is the best way to avoid the appearance of Error Code 0x8024001b and similar errors in the future, as stacked up updates are more likely to cause issues and conflicts with your other installed software and operating system.

While there are some tools out there that claim to be able to fix Error Code 0x8024001b for you, it is important to always thoroughly investigate the publisher and distributor of such software, as some of the tools available on the Internet will actually introduce malware and adware on your computer in the name of “protecting” your computer or resolving an error.

If you have tried to use both methods above and have not fully resolved Error Code 0x8024001b, get in touch with someone who is a qualified computer repair professional and is familiar with your particular version of the Windows operating system to assist you in finalizing your resolution.

Method Three: Use An Automated Tool

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.

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.

The previous Windows versions all came with Microsoft's browser Internet Explorer. A lot of users love it because not only that it is easy to use. It is also very fast. Users didn’t have to worry about compatibility because it is almost always compatible with its Windows Version. When they introduced Windows 10, they changed the name of the browser from Internet Explorer to Microsoft Edge. It is faster and more user-friendly compared to its predecessors. But after the Creator Update, some experienced receiving the inet_e_resource_not_found error code. In contrary to what everyone expects, you actually don’t have to uninstall and reinstall the Microsoft Edge App. What you can do is reset the browser in your Apps & Features Settings in your Microsoft Settings.

To reset the browser you can follow the steps below:

1. Click on the Windows icon and go to settings.
2. Click on Apps and this will bring you to the Apps & Features page. Look for Microsoft Edge from the list of Apps and click on it.
3. Choose Advance Option
4. Scroll down then Under Reset, click on repair or reset. When you repair it will fix the existing problem but the data that caused the problem may still be present and can still cause problems. If you click on reset, it will delete all the cache and cookies that are installed in your browser but it will save your Favorites as well as your bookmarks.

Another way to resolve this is by disabling the feature TCP Fast Open on Microsoft Edge. To disable this, go ahead and follow the steps below:

1. Open the Microsoft Edge browser.
2. Type in about: flags on the Address (URL) bar.
3. Under Networking, uncheck the Enable TCP Fast Open.
4. Close your Microsoft Edge browser and open a new one.

Flushing the DNS also worked for other Users. Sometimes, the error code the inet_e_resource_not_found is caused by a corrupted DNS cache. There are 2 ways to flush your DNS. The first option is to use the command prompt to run the command.

1. To access the Command prompt or CMD, you can search for it on Cortana or you can click on the Windows icon to access the Programs, scroll down to the Windows System folder and click on it.
2. A drop-down menu will show up, click on Command Prompt which is the first on the list.
3. Type in the code ipconfig /flushdns and press enter.
4. There will be a message that will show that says Windows IP configuration successfully flushed the DNS Resolver Cache
5. Exit the CMD by typing exit and press enter.

The easiest way to do this is to Press the keys Window + R on your keyboard. Type in ipconfig /flushdns in the search box and hit enter or click on OK. These are only some of the ways to resolve the inet_e_resource_not_found. There are other ways to further troubleshoot this issue such as reinstalling your Wifi Adapter Driver or adjusting the DNS Server Address. But most of the time, users are able to resolve the issue with the steps provided above.

Error code 0xc000021a - What is it?

Error code 0xc000021a occurs when the system is unable to start or there’s a failure in critical system processes. Normally, it would take about several seconds for the system to boot and while on the startup process, error code 0xc000021a may take place to block the system to boot up. Users will get a blue screen of death (BOSD) when this error occurs. When upgrading to Windows 10, be careful; you might encounter other error messages such as error code 8007002c. 

Solution

Error Causes

There are several reasons why error code 0xc000021a occurs. It is important to have a full understanding of what caused the blue screen of death before attempting to fix the error by yourself. See below for a few common causes:

• Computer malware has infiltrated your device.

• Important files such as Winlogon.exe and Csrss.exe are damaged. Winlogon.exe file is responsible for handling the login and logout processes while Csrss.exe is a vital part of Microsoft Client or Server ‘Runtime Server Subsystem’. Once one of these files is damaged or deleted, a stop error will occur.

• When there are mismatched system files installed or system upgrading process failed or still incomplete.

• Premature unloading of Wbemprox.dll

• Newly installed third-party software is not compatible with the operating system.

• There are corrupted, outdated, or incorrectly configured device drivers.

• There’s insufficient space in the system partition. Once the system partition is full, certain errors such as error code 0xc000021a will manifest.

• Windows registry is corrupted or damaged due to a software or system change. This means there are registry entries that are not cleared after uninstalling an application.

Further Information and Manual Repair

In fixing error code 0xc000021a, you might want to try and manually do so. Manual repair methods can give users effective and efficient solutions, addressing the root problems in relation to Windows error codes. Once the manual repair method is correctly implemented, users will be able to resolve issues immediately. However, there might be instances when a Windows professional is needed. In such cases, seek help from a certified Windows expert or you might want to consider using an automated tool whenever necessary.

Method One: Convert the Drive or Partition from NTFS to GPT

In order to fix Error code 0xc000021a in Windows 10, you might need to convert the partition or drive from NTFS to GPT. See below for the procedure: 1. Shut down your device then put in the Windows installation USB key or DVD. 2. Boot your device to the USB key or DVD in UEFI mode. 3. Inside the Windows Setup, open a Command Prompt window by pressing Shift + F10. 4. Type diskpart in the Command Prompt window to open the diskpart tool. 5. Type list disk to identify which drive to reformat. 6. Select which drive to reformat by typing select disk in the command prompt. Afterward, type clean then hit Enter. Once done, type convert gpt to be able to convert the drive from NTFS to GPT. Finally, type exit and press Enter. You can now close the Command Prompt window. 7. Once the partition or drive is converted from NTFS to GPT, the user can now continue the Windows Setup installation. NOTE: Select Custom in choosing which installation type to use. The drive will then appear as a single area of unallocated space. Choose that unallocated space then select Next. At this point, Windows will now begin the installation.

Method Two: Fix System File Errors
