uhhh, this actually worked--wtf. I used it to activate my windows 10 pro. I was using the insider program for a while to activate my windows. I mean this thing is like 6 CAD, i might as well give it at try. Bought one, slapped the key in and it worked. I activated mine on May 30th, 2020. Maybe this will be removed at a later date?

The key works as I expected. Thx.

Purchased, got code, and activated it on Hyper-V VM with zero problems. The test will be its long-term viability, but so far, pretty good.

got the key in 15 seconds

Bought this one year ago and no problem at all with the CD key.
Came here again because I need another for a friend's pc.
