Hurray for powershell!
The ConfigMgr console crashes, and the objects you were working on are locked. For the next 30 minutes.
Since ConfigMgr 2012 SP1 we have following cmdlet to our rescue:
Unlock-CMObject -InputObject $(Get-CMTaskSequence -Name “Install Application – DocsCorp Apps”)
In this scenario I was working on a task sequence called Install Application – DocsCorp Apps, when my console crashed.
Connect to Windows Powershell through the ConfigMgr console to load the proper module, and use the above cmd to unlock the object.
Following cmds are available:
Get-CMApplication
Get-CMPackage
Get-CMDriverPackage
Get-CMOperatingSystemImage
Get-CMBootImage
Get-CMTaskSequence
