Start button not working in Windows 10?

If the Start button is not working in Windows 10, try restarting your computer first, as this can resolve many temporary issues. If the problem persists, you can use the Task Manager to restart the Windows Explorer process. Additionally, running the System File Checker (SFC) tool through Command Prompt can help fix any corrupted files. If all else fails, consider creating a new user account to see if the issue is account-specific.
