Windows Latest Update

Looks like Windows recent update not only gave you the latest version of Windows but swallowed up at least 30 gigs of hard drive space. Now if you have enough hard drive space, then no need to worry about it because in 10 days the rollback software will automatically delete.
But if you in need of drive space, I would recommend on just waiting a little longer if you can to make sure Windows is stable enough before you delete. You decide.
