PENDING Windows.old removal

[Marcomile]

HI all,
can you suggest me a way to remove Windows.old after a 20H2 Upgrade using a script to run via SCCM?

That folder will be deleted automatically within few days. Do you still want to remove it ?

I saw that it will be deleted in 30 days but we have a lot of disk space issues , so I'd like to remove it on demand

Ok if you want to manually remove the windows.old folder, try these steps.

Right click C: drive and click Properties. Select Disk and from the list select the Previous Windows Installation(s) option to delete Windows.old folder.

I know ho to do it manually. My users have no admin grats on their PC, so I was looking for a way to push this command via SCCM

$path = $env:HOMEDRIVE+"\windows.old"
If(Test-Path -Path $path)
{
#create registry value
$regpath = "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches\Previous Installations"
New-ItemProperty -Path $regpath -Name "StateFlags1221" -PropertyType DWORD -Value 2 -Force | Out-Null
#start clean application
Start-Process "$env:SystemRoot\System32\cleanmgr.exe" -ArgumentList "/sagerun:1221"
Wait-Process -Name "cleanmgr"
}
