  1. Dism /Online /Cleanup-Image /RestoreHealth

    This did not work for me. It hangs for a minute or so at 20.0% and then I get the following…

    Error: 1726
    The remote procedure call failed

  2. This seems to be caused by a running process on your system. Can you go to task manager; and kill all third party programs/processes? Then run it again.

  3. Unfortunately,after trying several different suggested fixes, including this one, I finally gave up and decided to try reinstalling Windows 10. So far everything seems to be working as it should with the re-install. I intend to keep a very close eye on things this time around to see if I can pinpoint what might have led to the issue the first time around. I will keep you updated if I find anything.

  4. This is what appeared on my screen and I don’t know what to do next 🙁 ., I restart my pc thrice but this would still appear.

  5. Hey all, after running the scan, I get the message “Windows Resource Protection could not perform the requested operation.” Um… help please.

  6. Hi,
    I tried to run the sfc scan, but it told me that I needed to reboot my system. I did but it still gives me the same message. What should I do?

  7. DISM.exe /Image:C: /Get-Packages

    instead of DISM.exe /Online /Get-Pacages

    /Online can only be used in windows not in the Windows Preinstallation Environment (WinPE)

  8. You need to mount an image of win 10 and point DISM to it. This is how

    If you get the error message “cannot find source files”you need to have an ISO file mounted and need to specify where it is located with the below command

    DISM /Online /Cleanup-Image /RestoreHealth /source:WIM:X:SourcesInstall.wim:1 /LimitAccess Where “X” is the drive letter where the ISO is located. Simply change the “X” to the correct drive letter

  9. MINE SAID Error: 87
    The online/cleanup-image/restorehealth option is unknown.
    For more information, refer to the help by running DISM.exe/?.
    The DISM log file can be found at C:WINDOWSLOGSDISMdism.log

  10. MINE SAID Error: 87

    The online/cleanup-image/restorehealth option is unknown.

    For more information, refer to the help by running DISM.exe/?.

    The DISM log file can be found at C:WINDOWSLOGSDISMdism.log

  11. The e-mail issue then must not be caused by the corruption of system files. It could be a different issue. I suggest you post complete details of it on

  12. still keeps popping up the same message.
    could this be because I changed the accounts username some time back

  13. Please see my last response, you need to mount iso file and refer to the location as stated above. WIM:X:SourcesInstall.wim:1 /LimitAccess Where “X” is the drive letter where the ISO is located. Simply change the “X” to the correct drive letter

  14. Sir this is appearing on my Windows 8
