Two solutions
=============

Solution 1
===========

1. In Windows 11, gpedit is not available as default so we need to enable the gpedit first by typing the following in a text file and saving the file with any name, and the extension must be .bat file and close the file.

Paste the below content inside a .bat file

u/echo off pushd "%~dp0"

dir /b %SystemRoot%\servicing\Packages\Microsoft-Windows-GroupPolicy-ClientExtensions-Package~3*.mum >List.txt dir /b %SystemRoot%\servicing\Packages\Microsoft-Windows-GroupPolicy-ClientTools-Package~3*.mum >>List.txt

for /f %%i in ('findstr /i . List.txt 2^>nul') do dism /online /norestart /add-package:"%SystemRoot%\servicing\Packages%%i" pause

2. Right-click on the .bat file that you have created above and run as administrator. A command prompt will open and complete the process automatically. When the process is finished, the command prompt will tell you to Press any key to continue and then restart the PC.

3. Now click the window icon from the taskbar and type run to open the run box and then type gpedit.msc to open the Local Group Policy Editor window. 


Solution 2
===========

Open PowerShell as Administrator: Search for "PowerShell" in the Start menu, right-click "Windows PowerShell," and select "Run as administrator."
Run the following commands:

$pkg = (Get-ChildItem $env:SystemRoot\servicing\Packages\Microsoft-Windows-GroupPolicy-ClientExtensions-Package~3*.mum)
$pkg += (Get-ChildItem $env:SystemRoot\servicing\Packages\Microsoft-Windows-GroupPolicy-ClientTools-Package~3*.mum)
foreach ($p in $pkg) {dism /online /norestart /add-package:"$p"}

Restart your computer: This is necessary for the changes to take effect.

Open the Local Group Policy Editor: Search for "gpedit.msc" in the Start menu and select it.
