Hi, on my Windows 7 installation, there were several things not working: Disk management, Services, Management Console, etc. I ran SFC /scannow, and the result is attached. I also ran SFCFix, and the log file is below. I did provide the Windows 7 install files on USB drive when requested, and I was still left with several errors that couldn't be fixed. Thanks for your help!
