I noticed that after disabling Print Spooler on my servers where we don't use printing off these boxes and don't want to have any unnecesary services running on them, after some time on some of the machines Server Manager fails to refresh throwing "Role and feature refresh failed with the following error: The Deployment provider failed to initialize DISM. Error ..." How is Print spooler linked to that and why? I wasn't expecting it to have any such effect.
