block Alt+Ctrl+del for 20 seconds

[Epulone]

I have created a small macro script . To avoid the user could block the progress of the automate sequence (about 20 seconds) I would like to block  Alt+Ctrl+del just the time the script end in about  20 seconds.

How can I do it?

Thanks

Hi Rudi,

unfortunately BlockInput() doesn't block Alt+Ctrl+del

this is for security reasons, to avoid scripts wich trying hijacking a system.

In my case I mus block the user (student) to use them otherwise they will do (for sure).

Maybe I could disable by the register at the beginning and re-enable at the end. Could it work?

I can do it, but the forum is sensitive about scripts that look like keyloggers.

I also would not be asking for a keylogger neither. Against the forums.

[Epulone]

No, here there is a  misunderstand.

Mine is a genuine request. The script I am speaking about open a free legal software (Toolwiz Time Freeze) insert the admin password and activate it only when a student logon using the local student account of a university testing LAB. This to preserve the PC for any unwanted user change. The activation of the software require about 20 seconds where the student can use Alt+Ctrl+del to terminate the script and then mess all around ....

I hope you can see that here there isn't any  key-loggers scope .... I believe it is exactly the contrary .....avoid  any action from students  that could prevent the activation of the program by the script before they use the PC.

i believe what they are intimating is that a keylogger is the only way to do it, and we cant help you down that path.

As well, there are new built in defenses to Windows that warn the user when something is preventing the security screen from displaying when ctrl+alt+del is pressed.

google 'autoit ctrl+alt+del'.  There is no magic to be had, it's just thread after thread of futile efforts.

@Epulone you could set the group policy: "Prevent Task Run or End", would that work for you?

Also maybe you could just disable the del or one of the other keys entirely using scancode.

I believe that could work, but you will require to rummage into the registry. 

You could use #requireadmin along with regwrite function to do it for you.

But remember, you will need to reboot the computer in order to activate the change.

It is still possible to complete the script after reboot, but it will require some more scripting...

Isnt it easier to limit the students accounts in Windows so they cant kill the script?

that program, "Toolwiz Time Freeze", is rather poorly designed and extremely poorly documented. i installed it on a VM just to see if there was a help file available (there wasn't), and the "Help" section in the program UI sums up to this:

To active the Time Freeze mode with command line, you can try this way:
c:\xxx\ToolwizTimeFreeze.exe /freeze 
If you have set a password to protect the program, you can try this way:
c:\xxx\ToolwizTimeFreeze.exe /freeze /usepass=mypassword

To deactive the Time Freeze mode with command line, you can try this way:
c:\xxx\ToolwizTimeFreeze.exe /unfreeze 
If you have set a password to protect the program, you can try this way:
c:\xxx\ToolwizTimeFreeze.exe /unfreeze /usepass=mypassword
This operation will reboot your system automatically

To set the Time Freeze mode to be auto on with command line, you can try this way:
c:\xxx\ToolwizTimeFreeze.exe /freezealways 
If you have set a password to protect the program, you can try this way:
c:\xxx\ToolwizTimeFreeze.exe /freezealways /usepass=mypassword

---------------------------------------------------------
To install the Time freeze to your pc with command line, you can try this way:
c:\xxx\ToolwizSetup.exe /install /alwaysprotect=1 /reboot=1 /setpass=xxx /showtoolbar=1 /safemodequit=1 /cachesize=2000
then restart your computer to make the engine work.

To uninstall the Time freeze from your pc with command line, you can try this way:
c:\xxx\ToolwizSetup.exe /uninstall /reboot=1
then restart your computer to make the uninstall complete.

--------------------------------------------------
To get the protect state with command line, you can try this way:
c:\xxx\\ToolwizTimeFreeze.exe /check /usepass=mypassword

you can read the flag in the Registry.
HKEY_CURRENT_USER\Software\Toolwiz\TimefreezeNew
CURRENT_PROTECT_MODE = 1 means Time Freeze is ON.
NEXT_BOOT_PROTECT = 1 means next reboot, Time Freeze will be ON.

now, although minimalist, that description provides pretty much all you need - in the first two paragraphs.
