Same problem...... cant load WIM file anymore, maybe because its still loaded. But i cannot unmount the WIM either because it is not listed, and the files in the WIM are unerasable..... Any Ideas everybody ? Edit: Found the friggin Answer for my Problem ;-) for anyone who might have the same Problem, just do the following: 1.start CMD in Admin-mode and put in dism.exe /Cleanup-Wim 2.Maybe Restart.... 3.Enjoy 8-)
