Windows 11 has strict hardware needs. Use Microsoft's PC Health Check app to verify.

1. Download the PC Health Check tool from Microsoft's official site (search for it in your browser).
2. Run the app and scan your system.

Pro tip: If your PC doesn't meet specs, consider a clean install later. This step ensures you're not fighting an uphill battle from the start. 👍

Low storage can trigger the "Something Went Wrong" error. Aim for at least 64GB free on your system drive.

Action	Steps	Expected Outcome

Storage Sense	Settings > System > Storage > Turn on Storage Sense > Run now	Automatically removes old files

After clearing space, retry the upgrade. Users report this alone fixes up to 30% of installation hiccups.

4. Disable Third-Party Antivirus and VPN

Security software can block the Windows 11 upgrade. Temporarily pause it:

• Open your antivirus (e.g., Norton, McAfee) and disable real-time protection.
• Disconnect any VPN and ensure a stable internet connection.
• Restart and attempt the upgrade again.

Remember to re-enable protection afterward. This interference-free environment often lets the process complete smoothly.

5. Repair Windows Components with SFC and DISM

For deeper corruption, use Command Prompt as administrator.

1. Search for "cmd" > Right-click > Run as administrator.
2. Type sfc /scannow and press Enter. Wait for it to repair files.
3. Then run DISM /Online /Cleanup-Image /RestoreHealth.

These commands scan and fix system files, tackling the root of many "Something Went Wrong" errors. It's like giving your PC a tune-up! 🔧

6. Reset Windows Update Components

If updates are stuck, reset them manually:

1. Open Command Prompt as admin.
2. Stop services: net stop wuauserv, net stop cryptSvc, net stop bits, net stop msiserver.
3. Rename folders: ren C:\Windows\SoftwareDistribution SoftwareDistribution.old and ren C:\Windows\System32\catroot2 Catroot2.old.
4. Restart services: net start wuauserv, etc.
5. Reboot and retry the upgrade.

This flushes out corrupted update data, a game-changer for stubborn installs.

7. Perform a Clean Boot and Upgrade via Media Creation Tool

For persistent issues, boot minimally and use official media.
