  1. Unknown User - Powershell context menu - unable to remove permissions


    Running Windows 10 - poweshell.exe loads on startup (context menu).

    I am unable to remove it. There is an unknown user (see screen shot)
    Unknown User - Powershell context menu - unable to remove permissions [​IMG]
    that I can not remove from permissions. When I remove it, the unknown user reappears when I apply changes. I am the only user listed on the PC, I am unable to see "any other" users listed. I have full Admin user rights.

    I am trying to remove powershell from the computer but it keep reinstalling itself I once was able to delete all references to powershell, but it reinstalled as part of an update.

    After taking ownership and changing access rights on folders the files and registry entries to full access, they still cannot be deleted?

    I understand powershell is not needed in windows 10, but it may allow other users to remotely access my system?

    why does this unknown user auto give itself permissions after being removed?

    :)

    Locked Powershell startup command in context menu

    It seems that you cannot remove the folder because you don't have a permission to do so. To remove the two
    powershell.exe -noexit -command Set-Location '%V' on registry, we need first to set the permission to
    Everyone. To do so, kindly follow the steps below:

    • Open CC Cleaner
    • Go to Context Menu
    • Right-click on powershell.exe -noexit -command Set-Location '%V'.
    • Click on Open in RegEdit.

    • Right-click on the Powershell folder.
    • Click Permission
    • Click Advanced
    • Click Change
    • Type in "Everyone" without the quotation.
    • Click OK

    Also set the Administrator's permission to Full Control. After doing so, you can now delete the
    Powershell folder. Be guided that you need to do a backup of your
    Registry before doing the steps.

    Let us know how it goes.

  4. Unknown User - Powershell context menu - unable to remove permissions

    Locked Powershell startup command in context menu

    Hi

    I had thought it had resolved the problem of the 2 PowerShell scripts as I was able disable them in the context menu of startup. Unfortunately I'm not able to delete them, either in CCleaner or in the registry even though I set permissions to full control.
    That said CCleaner shows them as disabled.

    Have I missed something?

    Hi

    I had missed the section on applying full control to the command folder beneath the PowerShell one in regedit. Since I changed the permissions on the command folder as well I have now deleted the two scripts from the startup program list in the context menu.

    Many thanks for your help.
