Fix Black background behind Folder icons

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likely cause of this glitch might have something to do with the corrupted system files or it could also be caused by outdated thumbnail caches. In addition, graphical glitches like this one could also occur if you are using out outdated graphics drivers.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.

Option 1 – Try using the Disk Cleanup to remove Thumbnail files

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:

  • Open the Search bar and type “disk cleanup” in the field.
  • After opening Disk Cleanup from the search results, then from the drop-down menu select the C: drive to clean up and click OK.
  • Wait for the scanning process to complete. Once it’s done, select the files you want to delete.
  • Ensure that you select the box labeled “Thumbnails” under the Files to Delete section then click on OK.
  • After that, a confirmation box will appear, just click on Delete files to delete the files permanently.
  • Restart your PC.

Option 2 – Try resetting the Thumbnail cache

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.

  • Open the File Explorer.
  • Next, navigate to the View tab and select the option with Hidden items to display all the hidden folders and files.
  • Next, go to this path: C:Users<username>AppDataLocal
  • In the given path, make sure that you put your actual username in the username field. Then look for a file named “IconCache.db”. Right-click on this file and click on Delete.
  • After that, go to this path: C:Users<username>AppDataLocalMicrosoftWindowsExplorer
  • From there, select all the files and delete them.

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.

Option 3 – Try updating or reinstalling the Graphics driver

  • Tap the Win + R keys to open the Run dialog box and then type in devmgmt.msc and tap Enter or click OK to open the Device Manager.
  • Expand the section for the outdated device drivers.
  • And then select the outdated driver(s) and right-click on it/them.
  • From the drop-down menu, select the Update Driver option if you wish to update the driver or select the Uninstall device if you want to uninstall the driver and then follow the on-screen instructions to install the latest version of the driver.

How to Fix Windows 8 Error Code 0xc004f034

Error Code 0xc004f034 – What is it?

Error code 0xc004f034 occurs when Windows users are unable to activate their operating system. It affects Windows 8 and Windows 10 users and features common symptoms which include the following:
  • Inability to activate Windows
  • Message box with error code 0xc004f034

Solution

Restoro box imageError Causes

Error code 0xc004f034 often occurs due to an issue with the Windows product key. This may occur when users enter an invalid product key or use one that is appropriate for use on a different version of Windows. To correct the issue, users will need to use the correct product key for their system or contact an IT professional if their device is connected to a Key Management Service (KMS).  Windows users affected by this error code may also need to check their system for viruses or missing system files since these issues can result in error codes on Windows devices.

Further Information and Manual Repair

Manual repair methods enable users to fix problems related to error codes. Though some manual repair methods require the use of Command Prompt and utility tools like the System File Checker, even non-technical Windows users can find success simply by following the instructions provided below.

However, note that some issues can be complex, thus requiring the use of an automated tool or help from a Windows repair technician. Consider these options if the manual repair methods below do not resolve error code 0xc004f034 on your Windows 8 device.

Method One: Enter Valid Windows Product Key

Microsoft currently offers several ways for customers to activate their Windows operating system, the most common of which is the product key. This 25-character code verifies that users have access to an authorized version of Windows.

You may get a valid product key from an authorized dealer, a new PC with Windows, or access a digital copy from a Windows website when you purchase your Windows operating system online. Once you have a valid product key, use it to activate Windows and resolve error code 0xc004f034 in Windows 8. Follow the steps below to access the Product Activation Wizard.

  • Step one: Click or tab Start button then select Settings
  • Step two: Tap or click PC Settings, then select Activate Windows
  • Step three: Type invalid product key

Once a valid product key is used, the Product Activation Wizard should complete the activation process. If you are unable to complete the process, however, and error code 0xc004f034 remains unresolved, click the link or instructions the Product Activation Wizard provides regarding activation via phone or customer support.

Method Two: Run System File Checker

Another option available to Windows 8 users is System File Checker (SFC). This tool enables Windows users to scan and repair corrupted or missing system files. Follow the steps below to access SFC.

  • Step one: Go to Start and type Command Prompt or CMD.
  • Step two: Run as Administrator
  • Step three: Type sfc /scannow ensuring a space is between “sfc” and “/scannow”.

System File Checker will repair any corruptions found on system files within your machine once you successfully follow the instructions provided. The tool will also replace missing files which will lead to better performance on your PC.

When the process is complete, restart your device then check if you are able to activate Windows. If error code 0xc004f034 is still present, you will need to find another solution via repair method three.

Method Three: Scan for Viruses and other Malware

Viruses and other forms of malware are one of the main issues resulting in poor PC performance and Windows error codes. To fix this issue on your PC, scan your machine for signs of these malicious programs. If you do not have anti-malware software and would like to download one from the Internet, ensure the software you choose is effective before attempting to download it.

Once you have powerful antimalware software on your PC, begin a scan for viruses, Trojan horses, and other forms of malware. If the Windows error code occurred due to issues related to malicious programs, you will be able to resolve the issue. If, however, this manual repair method proves ineffective in resolving error code 0xc004f034, download a powerful automated tool or contact a Windows repair technician to assist you.

Method Four: Use an Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 8 and other related issues when they do arise, download and install a powerful automated tool.

Removing BEEP when adjusting volume in Windows
I often switch between my desktop speakers and headphones and because of this I very often use the volume adjustment bar to adjust sound levels so it is not too loud and each time when I set it I get annoying BEEP at the end. Now personally this might not bother you and you might want to leave it since it can be a useful feature to tell you how much volume is loud but if you are adjusting multiple times volume during the say it can become really frustrating to hear it each time, especially when switching to headphones and it beeps into your ears. In this guide, I will show you how to remove the beep so it is not heard anymore when you adjust the volume. Please know that beep is part of the Windows sound scheme and you can either remove specific sound with a completely silent wave or just turn off all windows alert sounds.
  • Open Windows settings and go to system > sound
  • in system sound, go to the right part of the screen and click on the sound control panel
  • In the sound control panel click on the Sounds tab
  • In the sounds, tab click on the drop-down menu under the sound scheme and choose no sounds.
There you go! You have successfully removed annoying BEEP each time you adjust the volume in Windows 10

Excluding a folder from Windows Defender scan
The Windows Defender program can both scan and monitor almost the entire folder on a Windows 10 computer. So if you have a folder that may have files that could trigger an alarm to Windows Security, then it would be better if you add an exclusion to Windows Security. Note that it is okay to do this as long as you’re certain that the contents of the folder you want to exclude are safe and that Windows Defender is only throwing out warnings for nothing. This way, Windows Defender won’t scan those folders in the future. And besides, there are also some Windows folders and files that you may exclude from the Antivirus scans, especially if you want to save your scan time. This kind of feature also comes in handy when you trust a file type or folder or any process that you believe is safe but the Windows Security considers as malicious. To exclude a folder or a file or process or a file type from the Windows Security scan, here are some steps you can follow. Make sure to do them carefully. Step 1: Search for “Windows Security” in the Search box and then click on it from the search results to open it. Step 2: Next, click on Virus & threat protection > Manage settings > Add or remove exclusions. Step 3: After that, on the next screen, click on Add an exclusion > Folder. It will show you a list that includes File, Folder, File Type, and Process. Step 4: Now click on “+Add and exclusion” on the next window and then select a folder you want to exclude and click OK to add it in the Exclusions list. Step 5: Click on the down arrow button to remove it and then click on the Remove button. Note: If you want to only ignore a few file types, it’s better if you configure your antivirus program to ignore these files with a specific extension. This way, it will ignore all of them no matter what their location is. Also keep in mind that when you select a folder, all the subfolders in it will also be excluded from the scan. Thus, you need to understand what you’re about to do. Once you’re done excluding the folder, it is recommended that you protect the folder using the Controlled Folder Access since this folder is not monitored for threat. The Controlled Folder Access will ensure that an external program does not alter it. This way, you can be sure that even though this folder is not included in the scan, it is still secure.

Task Manager is blank & not showing processes
If the Task Manager is either blank or is not showing processes on your Windows 10 computer, then here are a few things you can do to resolve this issue. This kind of problem can occur due to some system file corruption or some malware infection in the system. Here are some suggestions you can try to resolve the problem with the Task Manager on your Windows 10 PC.

Option 1 – Try restarting your computer

The most common and most of the time effective way to resolve this kind of issue is to simply restart your computer. Thus, you have to restart your computer and see if it helps in fixing the Task Manager issue or not. If not, you can try the next given options below.

Option 2 – Run the DISM tool

If the first option didn’t work, then running the Deployment Imaging and Servicing Management tool can help you resolve the issue with the Task Manager as it will repair the Windows System Image as well as the Windows Component Store in Windows 10.
  • After you access the Advanced Startup options, select Command Prompt by using the arrow keys on your keyboard.
  • Next, type in this command: DISM /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 3 – Make sure that the display columns are selected in the Task Manager

You have to make sure that you have checked or selected the display columns you want to be displayed. So if none of them are selected, you might not see any details at all. Thus, you need to right-click on the space near Name and select the columns.

Option 4 – Run the System File Checker Scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files that might be the reason why the Task Manager is blank or is not showing processes. To run the SFC command, follow the steps given below.
  • Tap Win + R to launch Run.
  • Type in cmd in the field and tap Enter.
  • After opening Command Prompt, type in sfc /scannow
The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:
  1. Windows Resource Protection did not find any integrity violations.
  2. Windows Resource Protection found corrupt files and successfully repaired them.
  3. Windows Resource Protection found corrupt files but was unable to fix some of them.
  • Restart your computer.

Option 5 – Troubleshot the problem in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the one that’s causing the Task Manager issue. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.
  • 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.)
  • From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Option 6 – Try scanning your computer using Windows Defender

As mentioned, the Task Manager issue might be caused by some malware in the system and so to eliminate the malware, you have to scan your computer using security programs like Windows Defender.
  • Tap the Win + I keys to open Update & Security.
  • Then click on the Windows Security option and open Windows Defender Security Center.
  • Next, click on Virus & threat protection > Run a new advanced scan.
  • Now make sure that Full Scan is selected from the menu and then click the Scan Now button to get started.
