Microsoft YouTube Account Hacked

Hi,

I have subscribed to YouTube's Microsoft's official channel. Got a mail that they have uploaded a new video and when I clicked on the link, the video doesn't seem official.
Checked their YouTube's Page and voila see the screenshot.


All the past videos uploaded by Mircosoft are gone. Hope YouTube's fix it soon.
Till that time enjoy the random upload's from the account asking for backgrounds. ;)

Update: New Background to the Account

Update: Another New Background to the Account

Update: And we are back again with "Epic Share"
