Hello all. I'm attempting to run the command of "DISM.exe /Online /Cleanup-Image /RestoreHealth" in an Admin CMD prompt window, but it keeps throwing an ERROR 87 back at me. Says it doesn't recognize the /Online /Cleanup-image /RestoreHealth option. I used the /? to read the help file, and it includes those options within the help, so I cannot figure out why it won't work. Anyone have any suggestions as to how I can get this to work with 64bit Windows 8.1 Pro VL, with all the latest updates and hotfixes installed? TIA!
