Upgrade Pre-Installed Windows 10 Home to VLSC Windows 10 Pro Without Wiping
We have an AIO (All-in-one) desktop at work that needed to be upgraded to Windows 10 Pro but since it has data on it, we didn't want to erase the machine to do a fresh Windows 10 Pro install. We were able to do the upgrade without having to wipe the machine and here's how that was done:
You'll need a Microsoft Volume License Service Center (VLSC) account and valid VLSC product key
- Turn on Windows 10 Home machine
- Go to Settings > Update & Security > Activation > Change Product Keys
- Turn on Airplane Mode
- Enter the generic Windows 10 Pro VK7JG-NPHTM-C97JM-9MPGT-3V66T product key
- Reboot the computer after it does the update
- Turn off Airplane mode
- Change the product key to your VLSC product key.
