Closed Upgrading Windows 7 Home to Ultimate Tags: Windows 7 Last response: September 5, 2012 7:09 PM in Windows 7 Share jomari29 June 13, 2012 3:39:23 PM Hey guys, My Current OS is Windows 7 Home Premium trial (been using the slmgr /rearm thing) and I just received a wonderful gift, a Windows 7 Ultimate Disc. So can i upgrade my OS without reformat?
