As per PTC articleCS40939 the DeleteWorkspaces utility which helps to delete workspaces of user is available only in Windchill 9.1 or earlier. This utility supports comma separated list of users whose workspaces need to be deleted. Whenever a user is disabled or leaves organization we need to cleanup such accounts in Windchill. This utility would help to automate the user cleanup process for offboarding users. Currently this is manual and very tedious process when we have to delete the workspaces of bulk users. This deleteworkspaces utility would really help in reducing a lot of manual activity and also reduce human error.
