Recently, we came around a strange issue that prevents us to open built-in snap-ins in Windows 10. The system on which we faced the issue has only single account and that was the administrator account. But still, system seems to be not recognizing that account level and keep throwing following error while opening snap-ins:

FIX An Administrator Has Blocked You From Running This App In Windows 10

If you’re facing this issue, there might be few reasons for it:

  • You lost the administrative rights
  • The snap-in might be blocked by Windows SmartScreen
  • A Group Policy setting is imposing a restriction on snap-in
  • Admin approval mode is enabled in UAC settings

In case if you’ve lost admin rights, you may not be able to open things which requires UAC permissions such as Registry Editor. So if you can’t select Yes or No for UAC permissions, you’ve lost admin rights. This problem can be fixed by following steps mentioned here.

For other causes, you may try fixes accordingly.

FIX: An Administrator Has Blocked You From Running This App In Windows 10

FIX 1 – Via Windows SmartScreen Settings

Sometimes Windows SmartScreen settings might block the snap-ins and thus they fails to load. So can try turning off Windows SmartScreen for a while and see if you could open the snap-in then. Simply select Don’t do anything (Turn off Windows SmartScreen) option.

1. Press W8K + R and put gpedit.msc in Run dialog box to open Local Group Policy Editor. Click OK.

    Hi. I can’t access neither to gpedit and secpol and changing configuration in smartscreen didn’t fix my problem with the red mmc.exe window.

  • Priscilla

    so what do you do if when you try to run gpedit.msc (while logged on to the PC as a domain administrator) you get the block? how do you continue?

  • hexaae

    Isn’t there a solution “per file”? Some ASUS software with laptops is without required certifcates and causes this but I don’t want to change system-wide behaviour. Instead I’d like to change this for single app only.

  • Kapil Arya

    ^^ Unfortunately, atm I am not aware of per-file solution.

  • anabi

    nothing works. I still can’t access through run, but I can access everything through search program ‘everything’.

    I am blocked from doing any of the fixes suggested here

    Thanks for the article! Unfortunately, I tried all 3 fixes but they either didn’t work or the feature was not available in W10 Home and my Admin Rights are Intact. Any other ideas I can try? TIA

  • Larry G Turner

    I was going to try Option 2 and got to the point where it says, “Open “gpedit.msc” It said, Cannot run rhis file – check the spelling and retry. Suggestions? I am using Win10 Home.

  • Kapil Arya

    ^^ That option won’t work on Windows 10 Home edition.

  • Larry G Turner

    Thanks for the reply! Will it work if I can find gpedit and download it to my W10 system?
    TIA

  • Kapil Arya

    ^^ Yup, but Group Policy is available on Pro, Enterprise, Education editions.
