Dear all !

First of all I want to thank you all for this forum. I created my Win7PE DVD with lots of input from here ....
Right now I am on a point I can't get further. I created a Boot CD for my parents where they can "nothing destroy" (no registry editor, no cmd, etc) ... right now, I think I did a good job, but in my final test I can push

CTRL & ALT & DEL

then I get a PE Shall swapper and I can open a cmd and other things.
I tried several Shells, I didn't get any to work. The BS EXplorer2 would work but, I can not automate the Frefresh Desktop & Refresh MenĂ¼ ...
When I use only the Pecmd my scripts aren't working / menue etc is not working ...

Now I use the Shell Loader and the Explorer Shell. System boots fine - but I can do CTRL & ALT & DEL and then the shell swapper is here again.
Is there any way (registry, etc... ) to deactivate somehow CTRL & ALT & DEL ???????

Please can anyone help me or give me a tip how to deactivate the keys or is there a way to block the Shell Swapper somehow ?????
Hope anyone can help, thank you !

nice greetings
Alex

Welcome  :smile:

You should be able to disable CTRl+ALT+DEL with
Code: [Select]
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\taskmgr.exe]
"Debugger"="Hotkey Disabled"


To enable, reactivate
Code: [Select]
Windows Registry Editor Version 5.00

[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\taskmgr.exe]


where they can "nothing destroy" (no registry editor, no cmd, etc) ... right now
You can maybe send your stuff, useful for others  :thumbsup:

Dear  ChrisR !

What an honor for me, my first post and the first reply the "Baker" of the very very cool Win7PE !! Let me thank you personal for this very very usefull and powerfull tool !! I spent hours and hours in this boot CD its such a great toy :)))

Thank you for your quick reply, I searched since 3 days about this CAD problem, I already have disabled the TaskManager

----
Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
"DisableTaskMgr"=dword:00000001
----

so I also tried your reg key - let me say I try it just in an virtual machine - and it didn't work. If I press "send CAD" to machine the Shell swapper pops up ...

I have to burn it on a CD because I am not sure
if there is any difference between a vmware or a real keyboard pressed CAD on a real machine ... ??
I will test it tomorrow and then I can tell you more !

yes, if anyone need my little scripts or tools I can share them. Most of them are registry keys ...

take care
nice greetings
Alex

I had not tried with Peshell in my previous post. Tested now, indeed, one or the other registry tweaks do not work with PEShell.

By cons, if you use Pecmd (Shell\0 - Shell loader), this key works here  :thumbsup:
Code: [Select]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\taskmgr.exe]
"Debugger"="Hotkey Disabled"
It can be made in PE without the need to reboot.
But, I have no success with the DisableTaskMgr Policy key even with Pecmd  :confused:

About the keyboard VM vs real machine, I guess that the keyboard scan code send to the computer should be the same.

Hi draxlea,

if there is any difference between a vmware or a real keyboard pressed CAD on a real machine ... ??
no  :thumbsup:
vmware, you can change combination key (at real side to send CTRL+ALT+DEL), and you can also test with virtual box ...

yes, if anyone need my little scripts or tools I can share them. Most of them are registry keys ...
Sure, open a topic
http://theoven.org/index.php?board=9.0
with your tools and plugins  :thumbsup:
it will be useful to whoever needs  :great:

*
PEShell have its own routine to catch CTRL+ALT+DEL,
you need to ask Pierre to put an option to disable it...

+
maybe you can find a way to reassign CTRL+ALT+DEL with something else  :wink:
pecmd + rename notepad.exe to taskmgr.exe  :wink:

:turtle:

Dear ChrisR,

My really big problem is, that I tried it with the Pecmd (without another shell marked) but, I can't boot up normally. Meaning, he isn't doing my BGINfo settings, doing my reg key settings, (all in autorun) etc ... nothing is working :( and I don't know why.... maybe I have to start over the whole project because I have disabled some tools which Pecmd is needed.... (whole ISO has just 290MB) I have really try to lock down the Boot CD. If I try Custom Pecmd I can edit some pecmd.ini but I don't know what to do ...

When I boot with BS Explorer 2 would be great because I disabled the CAD there, and I edited the menu also, BUT I can not automate a reload of the desktop, I can't reload the menu etc ... - there is no helpfile or anything :(

So with the explorer Shell everything works perfect - but there I can't disable CAD :) It's a challenge :)
Strange thing with my settings I have disabled the Taskmgr (right mouse click on tasbar and Taskmanager is grey you can't start it. I don't know why you can start it after importing the key ... ???

Dear Lancelot,
first I want to thank you also personal for your work with the plugins/software !!!
I have used it a lot and now I want to take the chance to thank you personal :)

Frist I have to say I just did little things to automate, noting big with my "lock parents down" and I really don't know how to do a
own plugin ... that was the reason why I didn't share it... First I will have to look that everything is working, than I have to look
how I build the plugin ... I will try my best.

I have had lots of ideas to deactivate the CAD keys - but nothing worked right now -
I tried to rename the taskmgr.exe, I try to remap the Ctrl key, try several registry keys, but it didn't work either ...
Maybe I will find another way to remap a key but right now I am not sure how to do but I will see ...

I had not tried with Peshell in my previous post. Tested now, indeed, one or the other registry tweaks do not work with PEShell.

Hi draxlea,

Try remaping Del key with D ;)

I just put update to Gena\Finals\1 Optimizations\'Scancode Map'
Here it is
https://www.dropbox.com/s/o7ctbm3rrs9hbxj/Lang_zz_Scancode%20Map.7z?dl=0

it works here on Gena, I feel it will work for you, one can live without Delete key ;)

besides be carefull , on normal life I do not advice remaping Delete key ....
maybe switching 'Delete Key' and 'Scroll Lock' is a better idea  :wink: so you know but parents don't   :wink:

Dear Lancelot,
thank you for your quick reply !! I've downloaded the script, imported and activated. Configured as remap DEL 2 D -
created Iso and testet in JavaVMBox - didn't work. Now I created a boot stick to test it physicly on a machine, I will try
it tomorrow and tell you ... I saw the "sharpkeys" software before but didn't get it how it works I was thinking I need
a piece of software on the boot CD also ... my miss understanding, maybe I have to look better again on the software.
Tomorrow I can tell you more !

Nice greetings
Alex

:Edit -

Today I tried it on a "real maschine" no VMWare - doesn't work also :( so its not the VMware ....
How can I switch to "Gena" project if there I can deactivate it ?

Ah ok, I just saw it looks like a "complete" different project ....
I downloaded it right now, in the night I will try to see how things are working in "Gena" and maybe I can move my things to
get also work in "Gena" ...

Right now I am not sure whats the difference between both (just projects ?) but in the evening I will read about the 2 things and try it ...

Hi draxlea,

I just could test,
replacing delete with d using
Lang_zz_Scancode Map

plugin worked here on both vmware and virtualbox
(tested Win7PESE x86 PE Shell, Win81SE x86 - OS, Win81SE x86 - PE)

I can't test real, but I feel you miss something...

ps: I mostly use Gena on tests since faster to test here, limited time  :wink:

See You
