The File Explorer in Windows 10 provides several ways to organize the contents of folders and files in the system. Windows users can utilize some efficient styles to view the contents of the file system as per the user’s requirement. A user may opt to display the file picture in large size thumbnails while the other one could opt to set the icons of folder and files in a small or medium size list. On the other hand, while setting up several styles for the folder and file icons, some Windows 10 users have experienced some unusual issues where there is the Black background showing up behind folder icons. They tried refreshing the File Explorer a couple of times but it didn’t help in fixing the problem and the black squares are still visible on some folder icons.
The black squares behind the folder icons might look disturbing though it’s not really a big problem and is merely a graphical glitch that does not cause any damage or whatsoever to the content of the folder and files. The most likely cause of this glitch might have something to do with the corrupted system files or it could also be caused by outdated thumbnail caches. In addition, graphical glitches like this one could also occur if you are using out outdated graphics drivers. To fix this problem, you need to follow the options laid out below.
The Disk Cleanup tool is one of the options you can try to fix the black squares behind the folder icons. Through this tool, you can delete all the Thumbnail files on your disk. To use it, refer to these steps:
You have the option to manually delete the Thumbnail Cache to resolve the black square background behind the folder icons issue. Follow the steps given below to reset the Thumbnail cache.
Note: If a prompt appears saying, “The files are in use and cannot be deleted”, simply select the “Do this for all current items” option and then click on Try Again. If you get an error message, click on Cancel to close the window and restart your computer.

Error Code 38 is a device driver error that users encounter on any Windows 2000 operating system and its following versions.
It occurs when the peripheral device that you connect to your PC cannot be accessed due to an inability of the Windows system to acknowledge the driver as a previous record of the driver being loaded is found in its memory.
It is a common error that users come across and appears on your PC with the following message:
“Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory. (Code 38)”
Error CausesError Code 38 is prompted when incomplete program files are left in the Windows system which damage or corrupt its files. There are various factors that contribute to this, some of which are:
The above triggers are very likely to create incomplete files within the Windows registry thereby leading to its damage and corruption.
This is especially true in the case of your PC when it has recovered from viruses when using anti-virus software. The anti-virus in its effort to remove the virus also could remove the files which contain them thereby increasing the risk of the error code.
These damaged files can severely impact the health of your PC and are imperative to fix it immediately to prevent further problems.
Although this error code may pose serious problems for your PC, thankfully, it is very similar to other PC driver errors and thus is an easy one to get rid of. Here are various methods that you can use to get your PC running smoothly again.
If restarting your PC does not help, you will have to find the exact nature of the problem by running the troubleshooting wizard for the device and then address the problem accordingly. To do this, proceed with the following steps:
After following the directions of the Troubleshooting wizard, make sure to restart your PC for the changes to take effect. Now check if your device is still causing problems.
If the error persists, you can use system restore to eliminate the problem. Here is how to do so:
By restoring the system via a last saved system checkpoint, you can obtain undamaged Windows system files that can help resolve the error code.
If using system restore does not work either, you may have to resort to manually uninstalling and then reinstalling the device driver causing the problem.
This would be necessary since the remaining incomplete files due to a partial removal or installation of programs are responsible for the error code. By uninstalling and reinstalling the device driver program, it would lead to the completion of the files.
You can do this by firstly logging in as Administrator and opening Device Manager. Select the device that is causing the problem and double click it; make sure that the peripheral is connected properly to the PC.
Upon opening, click on the ‘Driver’ tab and then select ‘Update Driver’. Make sure to refer to the system documentation that you received with your PC or computer to check for the motherboard details and driver specifics.
Manually uninstalling and reinstalling the driver will do the trick; however, it may be time-consuming especially when you would have to resort to your hardware user manual.
