    Run PowerShell Script As An Administrator


    Hi. So I've been searching online on a way to do this yet I cannot find a way to do it.

    _______________________________________

    I need this in specific:

    I want to double click a PowerShell script file (which will run as an administrator) from Windows Explorer that has this as the script:
    Set-MpPreference -DisableRealtimeMonitoring $true

    (that script requires that PowerShell needs to be run as an administrator)
    _______________________________________

    So those are the restrictions:
    No right-click>run PowerShell as an administrator
    No opening a shortcut to PowerShell (as an administrator) and pasting the command


    Thanks

    1 Set the ps1 up as an elevated task in Task scheduler.
    - [you will want to set up the TS task to use highest privileges but not to store the password in order to avoid creating a security hole but I do not have any tasks in that state to copy here as examples]
    2 Create a shortcut that runs the TS task and double-click that instead of on the ps1 script file itself.
    - [the shortcut format would be C:\Windows\System32\schtasks.exe /Run /TN "Name of TS task"]

    pepanee,

    I thought @Ztruker's link was an interesting solution for your case. I have been having a bit of a play with it and it seems to be reliable.

    The linked article contained comments about a couple of apparent shortcomings -

    1 There is an unspecified problem when running a self-elevating script that lives on a networked drive.
    - I have tried it with my test script and it seems to be fine.

    2 The self-elevated script cannot pass arguments to another script.
    - I did not bother to test this. I think that the problem might well apply to any exchange of arguments between elevated & non-elevated scripts and might have nothing to do with this method of self-elevation.
    - Scripts can also exchange arguments by writing to / reading from files [amongst other things]. I do this all the time [because I run a PS script from MS Office VBA] and it is a perfectly workable approach.

    There is another way of doing it, see On how to run a .ps1 file as Administrator - TenForums

    In this proposed solution, an interim script is run that calls the originally-desired script. This does not seem, to me, to be as neat a solution because you would end up with two scripts to maintain.

    Of course, there is always the elevating shortcut method. This requires one extra step compared to setting up such a shortcut for a batch file.

    1 Create a shortcut to your PS1 file [by, for example, dragging it with the Alt key pressed]
    2 Right click on the shortcut & select Properties
    2.1 At the start of the target field, type in powershell.exe then a space to separate it from the script's path-name
    2.2 Click on the Advanced button & set the Run as Admin checkbox.
    2.3 OK, OK
    {you will notice the shortcut's icon change when you do this}

    You can now double-click on the shortcut instead of your original script and it will run as Admin [after the normal Admin challenge].

    The extra step compared to doing this for batch files is 2.1. Batch files can be set to run as Admin without having to job the Target field.
