I can't even get back on my laptop. Just purchased last Friday from Frys. Back it goes. I don't have time or patience for this chit

@ Robert Aldwinckle on forums , it looks like the post you referenced related to a Kodak printer whereas showmethefacts is having trouble installing multiple Windows updates. If there is corruption of the service stack and DISM cannot fix it, then I am certainly out of my depth. I am still trying to convince Microsoft to provide Windows 8.1 install media for users with a Windows 8 key but so far have had no success.

What if it never stops undoing the changes?

@ Robert Aldwinckle on forums , is it possible that KB3018943 (a November 2014 IE/Flash upgrade) somehow never installed properly and that this is causing problems installing subsequent IE/Flash upgrades like KB3021953 and rollups like KB3000850? The next question is why DISM is unable to correct the corruption. I think DISM is trying to check that it has the stuff the OS would need if the current update were to be removed. I don't have that update any more either (assuming I ever did); it is that old. Please see the discussion I had with Richard to see why I think that this is probably a red herring here and not a real problem. In his case part of the thread took a detour investigating his Flash support for exactly this reason but in the end it apparently had nothing to do with his real problem.
