    Students changing Windows themes

    Anyone know of a workaround to prevent students using .theme files to change the windows theme under their profile? A small number are downloading high-visibility/horrendously coloured pre-defined themes and are double clicking them to apply them, only to find it cannot be reset under their logon restrictions, so we have to delete their roaming profile and let it create a new one to reset the theme.

    Thanks!

    Using Software Restriction Policy? We use Ranger for the blocking of applications, but as that doesnt allow blocking of certain filetypes we've never had need to use Software Restriction Policy until now. Will look into it, thanks.

    You can do it with Group Policy - give me 1 min to find the exact setting.

    Edit - User Configuration\Administrative Templates\Control Panel\Personalization\Prevent changing theme

    You can also force a pre-created theme with "Load a specific theme" if you have one available (this only applies to first logon / fresh profile however).

    or use file server resource manager and ban them from saving .theme files in users areas / profile shares

    Search for "services" file in start menu. Scroll down and find "themes". Then disable it.

    It turns out the 'Prevent changing theme' policy as mentioned in this post does not prevent a student from double-clicking a .theme and applying it into their profile, as we already have that enabled. It just means that once they apply the file they can't change it back!

    We're going to use Sted's suggestion of FSRM to ban them saving these files in the first place. Thanks everybody!

    It's been a while since I tested it, but there's a setting somewhere that blocks the themes window from opening. IIRC, even if you use .theme files they don't work.

    you could use gpp to tell .theme files to open with say notepad or probably just break any association for a group of users

    Ye, coz FSRM is fine for stopping them saving it to <somewhere> but it's no good if they run it from a USB stick
