Windows 11 Right-Click Menu Extremely Slow to Load

Hello,

Suggest you to run System File Checker scan:

1. Search for 'command prompt' using Cortana or Windows Search.

2. From results, right click on Command Prompt and select Run as administrator.

3. Type sfc /scannow command and press Enter key.

4. Let the command complete and then reboot the machine.

If issue still persists, perform clean boot:

Let us know if this helps!

In the Registry Editor, delete all context menu extensions under

 HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Shell Extensions\Blocked

and then restart File Explorer.

Since you've already ruled out a simple cache issue, the most effective solution is to clean up the registry entries that control your context menu. I'll guide you through two reliable methods: the first targets the most common culprit, and the second is a more comprehensive fix.
