Microsoft Windows 11 Windows 11 Upgrade from Home to Pro and Vice Versa Updated November 04 2025
If you are having issues upgrading from Home to Pro then follow these steps:
1. Install all available updates:
- Select Start > Settings > Update & Security > Troubleshoot.
- Next, under Get up and running, select Windows Update > Run the troubleshooter
- When the troubleshooter is finished running, restart your device
- Next check for new updates. Select Start > Settings > Update & Security >Windows Update > Check for updates, and then install any available updates
- Restart your device
2. Change Product (Activation) Key in Settings
- Select Start Menu > Settings> Updates and Security > Activation > Change product key



This video shows a generic product key which will let you upgrade your Windows. After it upgrades, you will need to use a different product key to activate it if your hardware doesn't already have a digital license set up. This may only work if you have the computer offline so it doesn't have an issue with the generic product key.

If you have issues doing the upgrade, try it from an Admin command prompt (using either generic product key or the real one, change the one listed below):
