Ask a new question

My PC has taskbar, settings and other junks of problems.

Well first off all the screen on my PC screen is just a blank white space then I noticed that my taskbar was just glitching out and not responding to my mouse and my keyboard shortcuts aren't working and my app's like settings, task manager and other stuff when I tap on them they say class not registered OR your device is not ready and my device doesn't have volume and when I go to volume mixer to raise the volume from 0 it says 'audio devices no audio devices installed' and I didn't even connect any other devices to it. So I hope I can get answers to fix my laptop thank you very much.

Hi Terna,

Welcome to Microsoft Community.

I'm Hahn and I'm here to help you with your concern.

I'm sorry to hear that you're experiencing issues with your PC. Several factors could be causing the problems you described, so let's try some troubleshooting steps to help resolve them:

1. Restart your PC: Start by restarting your computer. Sometimes a simple reboot can resolve temporary glitches.

2. Check display settings: Right-click on the desktop and select "Display settings." Ensure that the display settings are configured correctly, and the resolution is set to an appropriate value.

3. Update graphics drivers: Outdated or incompatible graphics drivers can cause display issues. Visit the manufacturer's website for your graphics card and download the latest drivers. Install them and restart your PC.

4. Run a system scan: Your PC might have malware or corrupt system files causing the issues. Run a full system scan using a reliable antivirus program and follow any recommended actions to remove threats.

5. A "clean boot" starts Windows with a minimal set of drivers and startup programs, so that you can determine whether a background program is interfering with your game or program. How to perform a clean boot in Windows - Microsoft Support

6. Use the System File Checker tool to repair missing or corrupted system files Use the System File Checker tool to repair missing or corrupted system files - Microsoft Support

7. Check for Windows updates: Make sure your Windows operating system is up to date. Go to Settings > Update & Security > Windows Update and click on "Check for updates." Install any available updates and restart your PC.

8. Re-register Windows apps: Open Command Prompt as an administrator by right-clicking the Start menu, selecting "Command Prompt (Admin)" or "Windows PowerShell (Admin)." Type the following command and press Enter:

PowerShell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRoot\ImmersiveControlPanel\AppxManifest.xml

9. Fix audio device issues: Open Device Manager (search for it in the Start menu), expand the "Sound, video, and game controllers" category, right-click on your audio device, and select "Uninstall device." Restart your PC, and Windows should automatically reinstall the audio drivers.

If there is anything not clear, please do not hesitate to let me know.

 

Your Sincerely
