Is there any way wherein we can disable the ALT+Printscreen and/or Printscreen functionality for a logged in user using any script in Big Fix ?

Hey Amit,
If you can find a way to do it with any utility, script, registry change, or file change, then we can do it through BES with a simple action.
Do you happen to know how to do it on a single computer?

Hi Amit,
I’ve got some good news for you, a colleague of mine Dominic and I saw your post and we’ve gone about trying to figure out how can we use BigFix to disable off the ALT+Printscreen and Printscreen functionality and have found out the method to do it.
So here’s the coding
Relevance Statement
(name of operating system = “Win2000” OR name of operating system = “WinXP” OR name of operating system = “Win2003”) AND (((not exists key “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout” of registry) OR (not exists value “Scancode Map” of key “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout” of registry)))
Action
regset "
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout
" “Scancode Map”=hex:00,00,00,00,00,00,00,00,03,00,00,00,00,00,37,e0,00,00,54,00,00,00,00,00
action requires restart
The scancode is based on a microsoft document for remaping of keyboard buttons, in the Scancode Map what we’ve done is to change the mapping of Print Screen and Alt-Print Screen to a null value thus the 2 key strokes are disabled.
On top of that this setting requires a reboot before it takes effect, as the Scancode is loaded in upon startup of the OS
This fixlet is only tested on a WinXP machine but through our research it is suppose to be applicable to Win2k and above.
Hope this is helpful!
Cheers,
Manwin

Hi Manwin,
regset “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout” “Scancode Map”=hex:00,00,00,00,00,00,00,00,03,00,00,00,00,00,37,e0,00,00,54,00,00,00,00,00
which positions inside of this string did you change to “00” ?
I suppose that the values inside are subject to be different on different keyboard layouts…
Regards,
Rolf.

Hi Rolf,
That is correct, the scan codes typically differ for other non-US keyboard mappings.
As long as you know the scancodes for the key you want to remap, this method should work for you.
For details on the format, pls refer to the below:

Hey Manwin, Dominic,
This works great, I have tested this and it worked.
I was still trying to find, as even put forth by Rolf, which values have been changed. Tell you the truth, I went through the doc and tried doing some trial and errors, but it did not work.
Cheers,
Amit

Hi Amit,
Here’s the basic idea.
hex:00,00,00,00,00,00,00,00,03,00,00,00,00,00,37,e0,00,00,54,00,00,00,00,00
the above string actually consists of a few blocks
00,00,00,00, <-null
00,00,00,00, <-null
03,00,00,00, <-denotes number of blocks following (includes last null block)
00,00,37,e0, <-mapping 1, changes E0 37 (printscreen) to null
00,00,54,00, <-mapping 2, changes 54 (Alt+printscreen) to null
00,00,00,00 <-null
It is important to remember that entries stored in the registry are always in little Endian format
Hope this makes it clearer.
