disable ctrl+alt+del

Ok yes you were correct .. try this one .. should fix that ..
(thanks for the heads up )

Sorry, but this is still really just a bad hack that would never be reliable or usable in a production application.

All you are doing is modifying the end users registry to stop their computer from functioning as they would expect it to.

They could still just open up regedit and change the values back.

Anyone with just some mild computer skills could easily bypass this in a few seconds.

Well works for me. Anyone with mid level computer skills can overide most anything .. in fact ... they dont need skills just to pull the plug.

Bottom line is it works, while some say it cant be done in VB.

PS. im not using this for normal PC software ... and no they cant access the registry in my software.

...Bottom line is it works, while some say it cant be done in VB...

Bottom line rory is - it doesn't work nor it can be done in VB6. You need to learn Windows OS, how it works and what major parts do. Task manager is just little utility and it is not part of security.

It doesnt work. hmmmm...
Others that have downloaded it would say otherwise.

Anyway Let the thread starter decide if it will work for him ...
If not .. i wont loose any sleep over it ..

BTW ... a computer is never going to be 100% secure .. there is always the power plug.
As to me learning the windows OS and especially "security" .. id teach you some things but you seem to "know it all".

[RhinoBull]

As I said "you need to learn..." before jumping to any conclusion. You are way ahead of wagon...

rory you keep saying pulling the power plug is a security hazard... how so? If someone pulled the plug on my PC and rebooted it, they won't be able to get into my PC without my boot password, they won't be able to get into my bios without my bios password, and they won't be able to get into windows without my windows password. They won't be able to get into my box to take my hard drives without the keys to the lock on the side....

So in your line of thinking.. I suppose I can say only a sledge hammer is a security vulnerability to my PC at the moment?


I am not trying to bash your code or anything.. I am just saying its a HACK. Its not the proper way to go about handling things.. its taking multiple side steps to try to accomlish something..

What if your program/pc locked up for some reason while it was being used, and forced the user to have to reboot the system.. now they boot and not only can they not access task manager because you changed their registry settings, but you also changed their login type.. and now they see a different login screen? Would you want to use software that changes your personal registry settings for your OS.. I know I wouldn't.. I would call that a virus.

Its securuty software .. not in the windows security software term though .. they never will have access to windows settings .. and it runs in another shell .. yes the 2nd part i did was a hack .. and the first code is Microsoft's code .. not mine .. bottom line is it may work for their purpose

A while ago I had to do this...

Method 1 requires no reboot to be performed.

Public Type NOTIFYICONDATA
cbSize As Long
hwnd As Long
uId As Long
uFlags As Long
uCallBackMessage As Long
hIcon As Long
szTip As String * 64
End Type

Private Const NIM_DELETE = &H2

Private Declare Function Shell_NotifyIcon Lib "shell32" Alias "Shell_NotifyIconA" (ByVal dwMessage As Long, pnid As NOTIFYICONDATA) As Boolean 

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long 

Private Sub KillTaskManager() 
Dim TaskMan As Long, Conf As NOTIFYICONDATA 
Shell "taskmgr.exe", vbHide 
Do Until TaskMan <> 0 
TaskMan = FindWindow("#32770", "Windows Task Manager") 
Loop Conf.hWnd =TaskMan 
Shell_NotifyIcon NIM_DELETE, Conf 
End Sub

Method 2 requires a reboot [you need to set Win usr+pwd because it is disabled in-kernel. Kernel memory is protected ofcourse, so you can't cheat windows into CopyMemory'ing your bits to the read bits in current memory]

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon : AutoAdminLogon = "2"

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon : DefaultUserName = username

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon : DefaultPassword = pass

Hope it helps... don't do anything naughty!

So did anyone end up finding a correct way to disable windows security thing and task manager? I can't really tell since someone disagrees with like every code posted.

[DigiRev]

Didn't you just post on the other CTRL+ALT+DEL thread? There were like... 3 working solutions in there.

[Shaq]

I don't think the ones in the other thread disable the windows security thing.

[RhinoBull]

It's impossible without the GINA. Common really, even stubbornness has its limitations.

[kleinma]

No one on this forum would help to bypass Windows security anyway. If they did, they would be banned and the posts would be removed.
