    I have tried the file deletion method but it isn't working.

    It's in as a .bat file within GPO for student logon, but does not delete any files.

    If I login as a local admin and run the .bat file manually then all the files are deleted.

    Any ideas why this is occurring?

    This high contrast thing for students is getting really boring (requires frequent profile deletions)!

    TIA

    Do it as a startup script rather then login

    As a general rule dont delete files, just deny the users group access using GP. When you go to patch and windows finds its missing standard files things can break/not install.

    glennda: not quite so bad here, but very frustrating.

    ZeroHour: the script has been activated here, so too late technically. Albeit I could setup another script to copy them back I suppose.

    I would personally and then use GP to deny a common users group (I would leave trusted installer and SYSTEM access though) that way any patches wont fail. Service packs will fail if they touch the files at least anyway as well. As long as you know you could have issues you can spot the problem.

    simply find out when the mode was first switched on, punish the user for what he did then none of them will do it again.

    simples

    Hey guys

    I found that Utilman.exe refers to the Ease Of Access button on the logon screen. However the LShift + LAlt + PrtScn is actually controlled by a process called Sethc.exe also in the System32 directory. What I did was I made the following batch file:

    rem This batch file will stop access to the High Contrast / Ease Of Access features. IE For Student machines.
    rem press any key to continue
    pause

    cd c:\windows\system32
    takeown /f sethc.exe
    takeown /f utilman.exe

    rem Now add disallow everyone permission...
    pause

    cacls %windir%\system32\sethc.exe /C /D Everyone
    cacls %windir%\system32\utilman.exe /C /D Everyone

    rem All done press any key to continue.
    pause

    Hope this helps someone!

    We had this, you can download administrator templates into group policy manager to disable the students from changing to high contrast in the intel driver panel (if you have intel motherboards) To remove the high contrast setting from a students account, we just delete their profile. They dont need roaming profiles anyway. If you need roaming profiles for students, you can always just rename the effected folder and log back on to automatically create a new one

    Do your students have roaming profiles then?
