    unexplained 100% disk usage at bootup after 81 update

    I just updated to 8.1 two days ago. I agreed to the update when my computer boot up, without issue, and was forced to reboot immediately (which, by the way, is idiotic. I wanted to do the install at night when I went to bed not lose my only computer for 1.5 hours that were suppose to be spent on volunteer activities because it won't let me delay the install!)

    When my computer next booted up it was SLOW. I opened up task manager and it showed me at 100% disk IO, even though non of the programs running used enough disk IO individually to be anywhere close to the 100% mark. Even after all of my programs *finally* finished booting up the disk IO still showed at 100%, but every program on my task manage showed less then 0.3 MB/s and most were at 0.1. Eventually the diso IO goes back to a reasonable level, but I had enough time to search all over google and fail to find any answers before my IO went to 0 so it was hardly immediately. This is substantially slowing my bootup process.

    I have checked all the bootup programs and they all look right. a *quick* scan of msconfig bootup (I already use a selective bootup from msconfig) looked right as well. I ran a malware scan and nothing came up. However, I didn't expect any of those to be the problem anyways. My computer was fin when it booted up without 8.1 I used it for 20 minutes visiting the same website I always do, then I was forced to do an install and everything was broken. This clearly sounds like it was caused by the 8.1 upgrade.

    I will update with screen captures of task manager when I next reboot; My disk IO stayed at 100% so long I figured I could take the captures when I needed them, then it finally went to 0% the one time I actually wanted it to stay at 100% lol.

    I must say this whole situation is taking my already strong dislike of window 8 and exasperating it; all of window 8 just feels like bad design decisions and forgetting that the majority of people running it are NOT on tablets. I already tell everyone to avoid window 8 if at all possible and am seriously considering switching to ubuntu just to get away from it.
