When logging of from an Ivanti Workspace Control session, which is running on a Windows Operating System that supports Tiles, the logoff hangs on "Saving start screen 88%".
This only occurs when the application CenterStack is active.
The CenterStack application blocks the use of Powershell during logoff.
The issue can be reproduced by uninstalling Ivanti Workspace Control and creating any type of Powershell logoff script. In this scenario, the script will also hang during logoff.
Issue is not Ivanti product related, report this issue to CenterStack.
