PowerShell: Protect all OU’s in Active Directory from accidental deletion

Posted by bartvdw on 1313/0808/2011

1) Check which OUs aren’t protected:
Get-ADOrganizationalUnit -filter * -Properties ProtectedFromAccidentalDeletion | where {$_.ProtectedFromAccidentalDeletion -eq $false} | ft

2) Protect them:
Get-ADOrganizationalUnit -filter * -Properties ProtectedFromAccidentalDeletion | where {$_.ProtectedFromAccidentalDeletion -eq $false} | Set-ADOrganizationalUnit -ProtectedFromAccidentalDeletion $true

3) Then rerun the first command to verify they have been changed.

These commands should run with "Active Directory Module for Windows PowerShell" for AD only or "PowerShell Modules" to load all of them.

AD DS: All OUs in this domain should be protected from accidental deletion

Reclaim disk space after service pack installation on Windows Server 2008 & R2 / Vista / 7

Posted by bartvdw on 1313/0808/2011

After installing a service pack you will notice that the used disk space is increased. This because of uninstall files. You can free up disk space by making the service pack permanent, meaning you can’t uninstall it anymore… This also counts for Vista and 7 installations.

Windows Vista SP1: vsp1cln.exe /verbose

Windows Server 2008 SP2: COMPCLN.exe /verbose

Windows Server 2008 R2 SP1: dism /online /cleanup-image /spsuperseded

More information in the deployment guides.
