High Contrast mode - users getting stuck

[glennda]

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

 

not that simple - tends to be friends who did it - which one - don't know

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

Hi All,

 

Regarding what I read in this thread High Contrast mode - users getting stuck, you are giving solutions to disable the key combination. I would like the students to be able to change to high contrast, but the problems is that they are stuck once they are in high contrast mode.

They are connecting to a RDC server.

 

Thank you for any help
