Cleanup & Disable Offline Files

Modified on Thu, 31 Jul at 11:38 AM

Run in Admin PowerShell:

# Disable Offline Files
Invoke-Command -ScriptBlock {
    Start-Process -FilePath "cmd.exe" -ArgumentList "/c sc config cscservice start= disabled" -Verb RunAs
    Start-Process -FilePath "cmd.exe" -ArgumentList "/c sc stop cscservice" -Verb RunAs
}

# Clear CSC Cache on next reboot
Invoke-Command -ScriptBlock {
    New-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\CSC\Parameters" -Name "FormatDatabase" -Value 1 -PropertyType DWord -Force
}

# Take ownership and grant permissions to Administrators
$folderPath = "C:\Windows\CSC"

# Take ownership
takeown /f $folderPath /r /d Y

# Grant full control to Administrators group
icacls $folderPath /grant "Administrators:F" /t /c

# Delete folder
Remove-Item -Path $folderPath -Recurse -Force

The last line, the deleting of the old files might not work and might need a restart first.
