The channel, which has 8 million views and over 25,000 subscribers, had 5 videos posted to it and now sits blank.
Posted to the channel by the hacker earlier in the day was the message "I DID NOTHING WRONG I SIMPLY SIGNED INTO MY ACCOUNT THAT I MADE IN 2006 :/."
Says Microsoft of the situation:
We are aware that someone has altered the YouTube channel devoted to Microsoft videos. We are working with YouTube to rectify the situation.
