I'll get to the point quickly: I installed a pre-activated Windows 7 Ultimate SP1 with all updates up to May on my new rig back in June, onto an SSD, using an UEFI setup. All was well, it was genuine. Afterwards, a week or so later, I installed a genuine Office 2013 package (free from University) that seems to have broken the activation and now my 30 days are up and I haven't found a solution. Things to know: Daz's loader doesn't work, because UEFI. KB971033 is installed, but was already installed with the OS itself. It can be uninstalled from the "Installed Updates" list. MS Toolkit doesn't work on Ultimate. I haven't tried RemoveWAT or any other options as of yet because I'd rather not mess something up. I don't really know what I'm doing. I would definitely not like to reformat. I'm fairly sure the Win7 distro used Daz's Loader v2.2.2 to begin with, and it worked despite the UEFI, but something seems to have gone wrong since. Any ideas? Thank you for your help in advance, I hope there's an easy way to solve this that I simply overlooked. I am posting this thread because the alternative options are quite confusing, particularly w.r.t. UEFI, so I thought I'd get an expert opinion before screwing something up beyond reasonable repair. By the way, if it matters, the mobo is an AsRock Z87 Extreme 4.
