Windows-Setup/Debloat

Debloating Windows

Windows mark a number of packages as "provisioned". Thus, they will persist in the system even when you right click and uninstall them or try to remove them through winget. Additionally, for apps installed from the Microsoft Store, they will continue existing in C:\Program Files\WindowsApps until it has been uninstalled by all users. winget also does not see packages installed by other users.

As such, if you want to make sure all of the annoying APPX/MSIX apps are gone, it is better to use Get-AppxPackage. The documentation is at https://learn.microsoft.com/en-us/powershell/module/appx/get-appxpackage?view=windowsserver2022-ps. Get-AppxPackage does not see Win32 packages, therefore you will still need to remove them using winget afterwards.

Steps to debloat

• First, go to Settings -> Apps -> Optional features and remove unnecessary features. I personally remove everything here.

• Next, scroll to the bottom and click "More Windows Features". Turn Windows features on or off and remove Features that you don't need. On my Parallels VM, I removed everything except Microsoft Print to PDF. If you are running bare metal, you should keep HyperV, Microsoft Defender Application Guard, and Windows Sandbox on.

• Reboot the system

• Run the Windows Terminal as an Administrator

• To get a list of packages that can be removed, run Get-AppxPackage -AllUsers | where {$_.NonRemovable -eq $false} | where {$_.isFramework -eq $false} | select Name,PackageFullName.

• Run Get-AppxPackage -AllUsers <PackageName> | Remove-AppxPackage -AllUsers to remove the unwanted packages.

• "Uninstall" the remaining annoying apps from the Start Menu. They are not really apps on the system, they are just annoying shortcuts which will install the apps when you click on them.

• Open the terminal and run winget list to see the remaining packages (note that this will not exclude Framework packages). Remove the remaining undesirable apps with winget remove <PackageName>. In most cases, this will just be OneDrive.

• For some reason, the Remote Desktop Connection app doesn't show up with both Get-AppxPackage and winget. Remove it with mstsc /uninstall. https://learn.microsoft.com/en-us/windows-server/remote/remote-desktop-services/clients/uninstall-remote-desktop-connection?tabs=command-prompt#uninstall-remote-desktop-connection
