Scripting Question

Removal of Windows.old after upgrade.

08/11/2016 777 views
I am currently working on a script to run cleanmgr.exe to remove C:\Windows.old without any user interaction. Everything works except I am still getting a prompt to confirm that I want to delete the folder and I won't be able to restore. I need to have this fully automated. Any idea's would be greatly appreciated.

Automates the Disk Clean tool to clean up all possible items for the given OS.

# V2 admin check
If (-NOT ([Security.Principal.WindowsPrincipal] [Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator"))
    Write-Warning "Please run this script as an Administrator!"
    Exit 1

# Create reg keys
$volumeCaches = Get-ChildItem "HKLM:\Software\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches"
foreach($key in $volumeCaches)
    New-ItemProperty -Path "$($key.PSPath)" -Name StateFlags0099 -Value 2 -Type DWORD -Force | Out-Null

# Run Disk Cleanup 
Start-Process -Wait "$env:SystemRoot\System32\cleanmgr.exe" -ArgumentList "/sagerun:99"

# Delete the keys
$volumeCaches = Get-ChildItem "HKLM:\Software\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches"
foreach($key in $volumeCaches)
    Remove-ItemProperty -Path "$($key.PSPath)" -Name StateFlags0099 -Force | Out-Null

Remove-Item c:\windows.old\* -Force -recurse

  • "If you clean up previous installations or temporary installation files, you will no longer be able to restore the machine back to the previous version of Windows. Are you sure you want to do this?"
