Already on Windows 11 Home? This upgrade key is the cheapest legitimate path to Pro. Building fresh or reinstalling? Get the full Windows 11 Pro product key instead.
The upgrade is an official Microsoft process built into Windows. When you change the product key on an activated Windows 11 Home machine, Windows verifies the new key online, switches the edition to Professional, and unlocks the Pro components already present in your installation. That’s why there’s no download and no reinstall — everything happens in Settings and finishes with one restart. Your Pro license then stays permanently attached to the machine.

Solid purchase overall. Saved a lot of money versus the official store price. No issues so far after a few weeks of use. 10/10 would order again.
Key arrived fast, much quicker than I expected. Activation was straightforward — entered the key and it went through first try. 10/10 would order again.
Glad I went with kymakers for this. Had to wait a bit longer than I hoped for the email, but it arrived. The software runs perfectly, no issues to report.
Received the code pretty quickly after the payment went through. Followed the instructions on the site and it activated without problems. Recommended.
No complaints at all — everything worked as described. The key worked on the first attempt. Really pleased.
