If Microsoft Windows 11 hasn’t compelled you to switch to a Mac or Linux yet, you’re likely seeing way more Copilot in your day-to-day. For my fellow geezers that lived through MSN and Bing, every so often Microsoft invests an enormous amount of money in a second-rate release that the only way they can get you to use it is by forcing it on you. Repeatedly. As of Windows 11 25H2 the history repeats itself and your boy Vlad is here to help you get rid of it (somewhat).
Start > Run > gpoedit.msc
This will open Local Group Policy Editor. Go down to User Configuration > Administrative Templates > Windows CoPilot and double tap Turn off Windows CoPilot.
Select Disabled and click on Apply / OK.
Now either reboot or run gpupdate /force from the command prompt and you shouldn’t see Windows Copilot again.
I want it gone-gone!
Read the opening paragraph again. Like herpes there is no getting rid of it, at best you’re managing outbreaks until the next major update where oops they’ve enabled it again. If GPO doesn’t do it for you, you can also remove the actual package. To do so launch powershell as an Administrator and run this:
Get-AppxPackage CoPilot -AllUsers | Remove-AppPackage -AllUsers
You now have Copilot-free Windows.
