@ 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.

When I checked my laptop (Windows 8.1 64-bit), I cannot find any record of that fix being installed nor does it appear in c:\windows\servicing\packages.

@ showmethefacts , the joys of working with the command prompt (:-). I would paste each command and then execute it by pressing enter. That said, it is possible that pasting all four and pressing enter will have executed the four commands. You can use a Windows Explorer to display c:\windows\logs\cbs and c:\windows\logs\dism to verify that the original logs now have a .log-20150310 extension. You could use Windows Explorer to rename the files if you login to your Admin account. I just find it easier through an Admin command prompt. It is the Dism /Online /Cleanup-Image /RestoreHealth command that generates (or adds to existing) cbs/dism.log files. You only want to run the command once after you have renamed the log files so that you capture (and upload) just the latest dism run. By the way, Windows Explorer allows you to drag and drop the two log files into your https://onedrive.live.com/ window.

OK, I know I this is tedious, but when yo say: "paste in the four commands in sequence to backup your existing log files," do I paste in one at a time and hit "enter" after each? Or do I paste them in all at once? I tried the latter to no good effect. And if I do the former, do I create a log after each one, thus making 4 cbs logs and 4 DIMs logs?
