Bought 5 keys for different systems over the course of two years.
The keys continue to work and activation is always successful. (with the exception of one key that did not work, which was quickly replaced by the customer support)

Key works fine as long as you telephone activate

Worked flawlessly. Thanks a lot!

Key ist fake, microsoft blocked key
