How to upgrade Windows 11 Home to Pro without reinstalling
You do not need to wipe your PC to get BitLocker, Remote Desktop and Group Policy. A Windows 11 Pro key upgrades Home in place in about ten minutes, keeping your files and apps.
Before you start
- A Windows 11 Pro product key
- A backup of anything irreplaceable
- Mains power or a full battery
- An internet connection
-
01
Back up
Nothing should go wrong, but copy irreplaceable files to OneDrive or an external drive first.
-
02
Open Activation
Settings → System → Activation and expand Upgrade your edition of Windows.
-
03
Choose "Change product key"
Enter your Windows 11 Pro key. Windows validates it and offers to upgrade the edition.
-
04
Start the upgrade
Click Start. Windows installs the Pro components and restarts once or twice. Leave the PC alone until the sign-in screen returns.
-
05
Verify
Back in Settings → System → About, Edition should read Windows 11 Pro, and Activation should say activated.
-
06
Switch on the Pro features
Search for Manage BitLocker to encrypt the drive, or open Settings → System → Remote Desktop to allow incoming connections.
If something goes wrong
Common snags.
"Unable to upgrade your edition"

Will my apps survive?
Yes. This is an edition change, not a reinstall — everything stays where it was.
Can I go from Windows 10 Home straight to 11 Pro?
Upgrade to Windows 11 first through Windows Update (if the PC is eligible), then follow this guide.
