@ Fares :
It seems like someone in your company has lost control of your VLK's, so MS has had it blacklisted due to its spreading among software-pirates.
Ask your IT dept. to get a new key from MS that is not blacklisted,
but be prepared to have your company de-headed for letting the key out in the open

Edit :
It seems like you have been ahead of the rest, as it will be officially released April 24,
try doing a new Win Update after the official release
