Today windows downloaded and installed SP1 automatically. After that, the power went off, when it came back and I booted the PC it started updating as it would usually do, it finished updating then rebooted and started updating again, this happened around three times (no failure, just installs over and over again). I became tired so I shut it down and it displayed "Failure configuring Service pack. Reverting changes", after that it rebooted again but began installing the SP once more, I rebooted again in safe mode and it began reverting changes once more only to reboot again and attempt to update once more.
Right now it's reverting changes once more and I'm just sitting here waiting and I don't know what to do (also, it's been reverting for quite a long time, around 30 minutes)
