It took me awhile to find a few cmd. prompts, so I thought it might be helpful to enter some command lines, & the community contribute some command line goodies: 1. dism.exe /online /cleanup-image /restorehealth 2. fsutil resource setautoreset true C:\ 3. from safe mode with networking: Type net user removevirus /add <enter> Type net localgroup administrators removevirus /add <enter> Type shutdown -r <enter> reboot and choose removevirus #1 & 2 From an elevated CMD prompt. I've found helpful with Windows Updates issues #3 Can be helpful removing bugs I've used #1 & 2 on win 8.1, not sure if both are available in windows predecessors Today I searched my records & online for #1 as currently I have WU issues. #1 gets 40% done, then 3 hrs later it's still 40% completed. I'll try again & see if it completes. If you guys feel this has merit, please contribute some cmd lines.
