Yes I am are you?
Yeah, I found some Google hits when I searched for this issue, but - may not be related.
When I first had the update fail on me, I recovered, uninstalled uxtheme patcher, some USB driver for a Korg synthesizer I have, and ATI - I wasn't sure and was just trying to remove new/potential culprits.
So obviously this gave me a new system restore point, the older one is no longer there, now I cna't restore at all.
Going to now see if I can hunt down the original system files and manually replace.
Weirdly though, after ux theme patcher uninstalling, nothing brong, and I also checked with sfc /scannow - but since I tried to update the last time, all the woes have really kicked in.
