This Windows 8.1 (x64 bit) problem is a tough nut to crack

Each software and each version brings its own bag of problems and a whole lot of bug fixes and patches.

Windows 8.1 is no different. Recently I came across a problem which I have not been able to solve but making all efforts to fix. This post describes the problem and the attempts to correct it.

Recently I copied over several hundred image/video files from my Windows Phone 8.1 Preview to my Windows 8.1 (x64 bit) Toshiba Laptop. This is when I started noticing problems. The computer became slow and I lost access to the properties of files / folders on the desktop. I also noticed that it
was not possible to run the command processor (cmd.exe) in the elevated mode which I required for some diagnostics. For example, if I right click any file, the rotating wheel would start and after a minute or so, the whole desktop would refresh as if nothing happened.

Of course I found some work arounds to achieve what I wanted but the OS was not operating as expected. You may find links to the work arounds here, and here.

After succeeding to run the SFC /scannow command in the elevated mode, I was able to determine that certain files were corrupted and could not be repaired. These files were posted to the forum and here is a list files that could not be repaired..

-----------------
In order to troubleshoot my original problem, I managed to repair the corrupt files using dism and then carried out a SFC scan of the computer (although this was not really necessary since dism provides the same informaiton). Now there are no corrupt files in the computer.

The original problem still persists. I am trying to further troubleshoot.
