is there a way to disable ctrl-alt-delete

I use BlockInput(1) on my scripts so users will not interfere with things...

but the first thing users do is press ctrl-alt-delete, then of course they can end processes

and take control of the system.

Is there any way to truly lock down a computer until a script has run?

I'm interested because a script I have written migrates profile and computer data to a server, and can take a long time to run.

I don't want anyone to have access until it has completed.

Thanks....

haha....

i thought of this problem before.....

the answer is "no, you cannot block ctrl-alt-delete"

well.. to lock down a computer, just WIN + L and set power button to do nothing

or if you don't want to WIN + L....

- monitor off

- make a full screen ,top most,boderless GUI

- _MouseTrap

- disable task manager

- enable welcome screen

- blockinput

- repeat the list every 20sec

haha..... The problem is how do you unlock every thing after you did this....(by usb maybe...)

I have a screen which shows the progess of copying,

I want the users to see this at all times, but not be able to stop it in any way.

I have already disabled screen savers etc..

So this can't be done in anyway using autoit?

There is always a way .. somehow ;)

not the way I use a hammer :evil:

The other possible solution is just run a lockscreen program before you initiate your process of uploading and after uploading is finish, just unlock the screen. The main problem of doing that is the user wont be able to do anything on computer until its finished.

A lockscreen program is basicly a utility that just block the keyboard and mouse until a correct password is input(you to create a password before you lock it).

And the screen is basically semi transparent whereby you can see whats going on the computer monitor.

Now the main problem is how to a made a lockscreen program? ;)

Especially one that can accept commandlines(that way I can use it too. :evil: )

Put this at the top of your script:

#include "Misc.au3"
BlockInput(1)
_MouseTrap( 0, 0, 1, 1 )

And this in the main loop.

If ProcessExists( "taskmgr.exe" ) Then
        ProcessClose( "taskmgr.exe" )
        WinActivate( $hwnd )
        BlockInput(1)
        _MouseTrap( 0, 0, 1, 1 )
EndIf

I have had good luck with this little chunk of code. It pretty much disables everything. Very hard to get out of.

This thread is 5 1/2 years old, pretty sure the original poster wouldn't need this by now, if they were ever to return here. The OP hasn't been here in 4 years.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.

This is security circumvention and is not a permitted discussion topic. (See forum rules.)

Apart from that: this should never be done in this way by well-intended programmers anyway. If you are a corporate sysadmin, use domain policies to prevent non-administrator users from doing things you don't want them to. If you write your script for users over whose computer you should not have that kind of control, you are in fact writing malware. You don't want that.

/edit: BrewManNH good point :D Hadn't noticed. Point would have been exactly the same 5 years ago though :)
