I'm looking to leverage the "Show VMware UEM logon and logoff progress information" GPO, without leveraging a GPO I was hoping it to be an option I could add to the NoAD file, but I haven't found anything for it yet. I'm not extremely hopeful, since in the description of the GPO, it says "When this setting is enabled, a splash screen with a progress bar is shown when FlexEngine is called from a script."
You can configure Show VMware UEM logon and logoff progress information to show a splash screen with progress bar when FlexEngine runs.
If you use Windows 8 or newer, the splash screens at logon and logoff never work. Also not with the Group Policy Extension.
Windows always shows it's own 'welcome' screen on top of any other splash screens.
