I'd tried it yesterday, it's fixed something, but not solved my problem.
I'll try it again.
Strange
Hi I have a TABLET Dell Latitude 10 ST2 Windows 8 Pro. Same problem here, update fails undoing screen. I tried the fix windows update advice above and it fixed 2 items. I noticed that this time it took a lot less time for windows update to download the updates, say 20 minutes (it took upwards of 1-2 hours in the past).
I am waiting for the "preparing to install" thing to stop, to finally get done, and its taking a while. It's been at least 40 minutes. Before this fix try I tried setting 3 things to Automatic in Services, being led by someone on YouTube. That didn't work. I fell asleep last night while the updates were installing, when I woke up at 8 am it had failed hours and hours previous, signifying that waiting 30 minutes doesn't do anything to help you.
We'll see here in a few if it worked. I'll keep posted. I hope there is someone still alive here.
