    Damn, stumped again. Can't get Powershell Get-Acl to work with this key. Doesn't seem to like the space in Windows NT, even when I surround the entire key in double quotes. What the heck am I doing wrong this time? This is from a Admin Powershell Window.

    PS C:\Users\ztruk\PowerShellScripts> Get-Acl -Path "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EditionVersion" | Format-List
    Get-Acl : Cannot find path 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EditionVersion' because it does not exist.

    The path is correct:

    C:\Users\ztruk>reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EditionVersion"

    It should be -

    Get-Acl -Path 'HKLM:SOFTWARE\Microsoft\Windows NT\CurrentVersion\EditionVersion' | Format-List

    Damn! The example even shows HKLM: but I tromped right over it.

    Thanks all. Seems I'm my own worst enemy sometimes.

    Anyway, shows Owner is TrustedInstaller and Administrators have Read access which is the info I was looking for without using regedit.

    Code:
    C:\Users\ztruk>Powershell Get-Acl -Path 'HKLM:SOFTWARE\Microsoft\Windows NT\CurrentVersion\EditionVersion' ^| Format-List
    
    
    Path   : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows

    From a Command Prompt it should be:

    Powershell Get-Acl -Path 'HKLM:SOFTWARE\Microsoft\Windows NT\CurrentVersion\EditionVersion' ^| Format-List

    The regini.exe input file I'm creating on the fly contains:

    \Registry\machine\software\Microsoft\Windows NT\CurrentVersion\EditionVersion [1 6 9 17]

    I was following info from here as a guide: [Windows Tip] Take Ownership (Permission) of Registry Keys from Command Line

    Change Owner of File, Folder, Drive, or Registry Key in Windows 10

    Scroll down to METHOD 3: Set Permissions on Registry Keys Using Built-in REGINI Command

    If I understand correctly, one line of commands will do the job.
    Code:
    Echo \Registry\machine\software\Microsoft\Windows NT\CurrentVersion\EditionVersion [1 6 9 17]>%Temp%\T.txt & REGINI %Temp%\T.txt
    What is the problem?

    Code:
    Echo \Registry\machine\HARDWARE\Testing [0]>%Temp%\T.txt & REGINI %Temp%\T.txt
    The above [0] will remove all permissions.

    What is the problem?

    First, I don't want it on one line, I want readability. 2nd, it doesn't work. No permissions are changed.

    Code:
    Echo \Registry\machine\HARDWARE\Testing [0]>%Temp%\T.txt & REGINI %Temp%\T.txt
    The above [0] will remove all permissions.
    Don't know if that will work either and not willing to try it since I don't want to lose permissions to the key.

    I believe the problem may be that you have to take ownership before trying to change the ACL permissions. I'll play with that and see.
    This doesn't work with subinacl either so I again think ownership is the key.

    SUBINACL /keyreg "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EditionVersion" /setowner=administrators /grant=administrators=f

    It work if the key is HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows but it doesn't like Windows NT for some reason. I found this out by accident when I removed the double quotes from the key.

    Okay, finally got it working. Had to switch to SETACL from Helge Klein instead of REGINI or SUBINACL.

    Here is the working code:
