Windows 10 pro key, work just fine ....

Purschased it and activated it without any problems at all. went in CMD after and ran "slmgr /dli" To check if it indeed was a pro retail key which it was, so it's legit. at least for me

Worked perfectly on an installed Windows 10 Pro! Just copy paste activation code and done.

Ich wahr zuerst skeptisch und dachte das es fake ist.
Hat alles super geklappt.

This is actually a fuking retail key
you can check from your cmd and type slmgr/dli
bout one from another source and it was a Volume but claimed to be retail.
good shit man.
