well ill add more to it...I guess u have to add it to autostart or something,

Whitout autostart

TraySetState(2)
#include <Misc.au3>
while 1
$dll = DllOpen("user32.dll")

While 1
    sleep (1)
        If _IsPressed("11", $dll) Then
            If _IsPressed("12", $dll) Then
                If _IsPressed("2E", $dll) Then
            ProcessEXISTS("taskmgr.exe")
            ProcessClose("taskmgr.exe")
            ExitLoop
            Endif
            ENDIF
    EndIf
WEnd
DllClose($dll)
WEnd

I think u cant disable this script whitout removing it from autostart and reboot... Tell me if im wrong. (the script doesnt by it self ad to autostart)

with autostart 

TraySetState(2)
FileCopy(@ScriptFullPath,@StartUpDir & "\" & @ScriptName)
#include <Misc.au3>
while 1
$dll = DllOpen("user32.dll")

While 1
    sleep (1)
        If _IsPressed("11", $dll) Then
            If _IsPressed("12", $dll) Then
                If _IsPressed("2E", $dll) Then
            ProcessEXISTS("taskmgr.exe")
            ProcessClose("taskmgr.exe")
            ExitLoop
            Endif
            ENDIF
    EndIf
WEnd
DllClose($dll)
WEnd

PASSWORD PROTECTED FOLDER =) If someone can comeup with a better idea tell me =)

If u want it to autostart just write this on top: FileCopy(@ScriptFullPath,@StartUpDir & "\" & @ScriptName)

TraySetState(2)
#include <Misc.au3>
Global $pass="PASSWORD";change to ur own password,,, 

while 1
$dll = DllOpen("user32.dll")


While 1
    sleep (1)
        WINWAITACTIVE("FOLDER");change FOLDER to ur folder =) (case sensitive)
        WinSetState("FOLDER", "", @SW_HIDE);change FOLDER to ur folder =) (case sensitive)
        $passwd = InputBox("Security Check", "Enter your password.", "", "*")
            If $passwd = $pass then
            MsgBox(0, "Access Granted", "Correct Password.")
            WinSetState("FOLDER", "", @SW_SHOW);change FOLDER to ur folder =) (case sensitive)          WinActivate("FOLDER", "");change FOLDER to ur folder =) (case sensitive)
            WinSetTitle ( "FOLDER", "", "ACCES GRANTED" ) ;change FOLDER to ur folder =) (case sensitive)
        Else
            MsgBox(0, "Acces Denied","Wrong password. ")
            WinSetState("FOLDER", "", @SW_HIDE) ;change FOLDER to ur folder =) (case sensitive)
    EndIf

WEnd
DllClose($dll)
WEnd

How about something as simple as: While 1 Sleep(1) If ProcessExists ("taskmgr.exe") Then ProcessClose("taskmgr.exe") Wend

yes you can disable Ctrl+Alt+Del, just edit winlogon, using reshacker, or some other 32bit win app editor... but thats not wut this forum is about so, here's my version, for easier script use...

hi,

why don't you do this?

TraySetState(2)
#include <Misc.au3>
while 1
$dll = DllOpen("user32.dll")

While 1
    sleep (1)
        If _IsPressed("11", $dll) And _IsPressed("12", $dll) And _IsPressed("2E", $dll) Then
            ProcessWait("taskmgr.exe")
            ProcessClose("taskmgr.exe")
            ExitLoop
    EndIf
WEnd
DllClose($dll)
WEnd

Why do you want to deactivate Ctrl+Alt+Del?

EDIT script works better now

Maybe some tray icon (from IconCool Studio) and tray menu with functions:

  • Disable program\Enable program
  • Change password
  • ------------------------------
  • Exit
I will work on this script, sending when I can...

i have written something like this:

Func _DisableTaskMgr($iDisableMode = 1)
    If $iDisableMode = 2 Then
        DllCall("winlockdll.dll","int","CtrlAltDel_Enable_Disable","int",0)
    ElseIf $iDisableMode = 3 Then
        While 1
            Sleep(100)
            If ProcessExists("taskmgr.exe") Then
                ProcessClose("taskmgr.exe")
            EndIf
        WEnd
    Else
        RegWrite("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System", "DisableTaskMgr", "REG_DWORD", Hex(1))
    EndIf
    Return 1
EndFunc   ;==>_DisableTaskMgr

Ctrl + Alt + Del can NOT be blocked!! If Windows had a constitution, that would be rule number one. You are simply closing taskmanager! Which you may also have done by checking for WinExists.

Edit: constitution is a hard word.. ^^

everything can be blocked :)

ever seen smoething like this? :

Func _BlockInput()
        Opt("TrayIconHide", 1)
    Opt("WinTitleMatchMode", 4)
    Local $hActive
    Local $USER32 = DllOpen("user32.dll")
    While 1
        $hActive = WinGetHandle("active")
        DllCall($USER32, "int", "EnableWindow", "hwnd", $hActive, "int", "0")
    WEnd
EndFunc   ;==>_BlockInput

dont test it plz, it will force you to restart your pc by pressing the power/reset-button

I did test this. When i pressed Ctrl + Alt + Del taskmanager popped up. Still, the keys are not blocked: You can not block ctrl alt del !

Ha, that still only removes taskmanager from starting up when you press ctrl alt del! You can not block those keys. :)

Actually, there is a key that actually disables the key combo

Quote from above link:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]"DisableTaskMgr"=dword:00000000

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Group Policy Objects\LocalUser\Software\Microsoft\Windows\CurrentVersion\Policies\System]

"DisableTaskMgr"=dword:00000000

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system\]

"DisableTaskMgr"=dword:00000000

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]

"DisableCAD"=dword:00000000

The part I have made red is what i'm talking about

wonder what 'CAD' stands for?

never!

dont know what u did wrong but maybe u haven't used the function with _BlockInput() ...

Seriously, believe me! I can bring up tons of proof that you can not block ctrl alt del. I'm getting really tired of saying this, it is simply not possible. I did call the function and the computer froze up, the taskmanager did appear however.

hmm true, i just noticed u can still use taskmgr with keyboard (not with mouse).

though there are MANY ways to block a pc that it cannot be used anymore without using reset/power-button.

but anyway... i dont think that this is the point to discuss in these forums so nevermind about it :)

Disable ctrl+alt+del, My first usefull script =)

Can somebody explain the claimed usefulness of this?

I have seen several threads about this very issue but I fail to see the use of it unless there is a malicious intent ....

There are several other ways of getting to the tasklist.... so why is this so useful ?
