Liam Posted May 15, 2007 Posted May 15, 2007 In our school we are having increasing problems with keyboard shortcuts. Children have now started to Switch High Contrast either on or off). To do this they simply press alt, shift and print screen. Does anyone know how to do this or have a GPO written?
plexer Posted May 15, 2007 Posted May 15, 2007 You mean you want to restrict their ability to do this? Probably breaks some DDA regs as then the students that need it wouldn't be able to access it? Ben
OutToLunch Posted May 15, 2007 Posted May 15, 2007 The registry key for it is HKCU\Control Panel\Accessibility\HighContrast\Flags , "122" is disabled. For some reason I managed to read plexers reply as "You mean you want to restrict their ability to do this? Probably breaks some legs"
Liam Posted May 15, 2007 Author Posted May 15, 2007 Yes i thought that this would cause some problems. I never thought of it that way though. Thanks for your reply it was very helpful.
stephenleak Posted May 15, 2007 Posted May 15, 2007 Erm, if you try this, it says about deactivating the key combination by clicking the Settings button. If you do this you get another window. If you click the Settings button on that window, you get yet another window with a tick box to deactivate the key combination. It looks like it is one of the Accessibility features.
TechMonkey Posted May 15, 2007 Posted May 15, 2007 Tested this on our user type and they can't do it. We have Accessibility disabled in the GPO except for students that need it. So if you can restrict that then it shoudl restrict the key combi. HTH
Liam Posted May 16, 2007 Author Posted May 16, 2007 THANKS THATS VERY HELPFUL. I WILL GET ONTO THAT NOW.
maniac Posted May 17, 2007 Posted May 17, 2007 Has anyone else ever tried pressing CTRL-ALT-ESC in internet explorer? I don't know what it does, but it crashes internet explorer completely. Also apparently some of the kids in this school have found a way of disabling the keyboard of a machine by using a key combination. Problem is I don't know what combinition it is yet!! mike.
Geoff Posted May 17, 2007 Posted May 17, 2007 CTL-ALT-ESC is the keyboard shortcut to load taskmanager. But only on windows 2000. CTL-SHIFT-ESC loads task manager. CTL-ESC opens the start menu. ALT-ESC switches windows like ALT-TAB (minus the popup).
ZeroHour Posted March 4, 2008 Posted March 4, 2008 The VBS script has been added to the wiki. Goto: http://www.edugeek.net/wiki/index.php/Disable_Sticky_Keys_and_High_Contrast
6Foot2 Posted March 4, 2008 Posted March 4, 2008 Tested this on our user type and they can't do it. We have Accessibility disabled in the GPO except for students that need it. So if you can restrict that then it shoudl restrict the key combi. HTH Where IS the accessibility setting? Can't find it and I want to set it on the student OU down. I will create an OU that takes care of issues for visually impaired students if I am notified about them.
ZeroHour Posted March 4, 2008 Posted March 4, 2008 Control panel settings would be my guess. The script blocks them using it as even disabling it in the gpo wont block the keystrokes from triggering the options I believe. 1
6Foot2 Posted March 4, 2008 Posted March 4, 2008 (edited) The VBS script has been added to the wiki. Thanks for the pointer to the script. Works for my Technician user but no others. I think I will incorporate the changes in to the image and roll out the changes next time the stations need a refresh... Edited March 4, 2008 by 6Foot2 Correct spelling mistake
ZeroHour Posted March 4, 2008 Posted March 4, 2008 hmm it works for us fine. The user must log off and log back on for the keys to be disabled. try a gpresult using GPMC to confirm its running.
Friez Posted March 4, 2008 Posted March 4, 2008 We have special accounts setup for anyone who has a DDA requirement, so we have absolutely no problem with killing magical keys like this.
richard.thomas Posted March 5, 2008 Posted March 5, 2008 Why did i try and use CTRL + ALT + ESC after being told that it crashes IE!? It's like having a big red button "DO NOT PRESS"... I pressed it
tomscaper Posted March 5, 2008 Posted March 5, 2008 I have applied this but when i press the shortcut it pops up a message about turning high contrast on. Do you run the script on logon or on startup, or both. It is currently set for logon, does the script run under there logon or as an admin, could it be an access issue.
ZeroHour Posted March 5, 2008 Posted March 5, 2008 It should be in logon for the users yeh. Try logging off and on and see if it works then. Its a user registry key so no admin is needed.
tomscaper Posted March 5, 2008 Posted March 5, 2008 currently have this in the logon script 'Turns off StickyKeys wshShell.RegWrite "HKCU\Control Panel\Accessibility\StickyKeys\Flags", "506", "REG_SZ" 'Turns off high contrast wshShell.RegWrite "HKCU\Control Panel\Accessibility\HighContrast\Flags", "122", "REG_SZ" 'set high contrast theme wshShell.RegWrite "HKCU\Control Panel\Accessibility\HighContrast\High Contrast Scheme", "Windows Standard", "REG_SZ" Have i missed anything or made any mistakes. With this it still does not disable it.
Joanne Posted March 5, 2008 Posted March 5, 2008 hmmm... now I've done it and I can't get it back!!! Silly me! Hah... so has the other guy! We're silly!
ZeroHour Posted March 5, 2008 Posted March 5, 2008 tomscaper: Can you just paste whats in the wiki and create a new logon script and see if it works then. It may be a problem in the script you are using.
