PC Restraint - Password Locked Kiosk Style Computer

CURRENT UPDATE - 23 SEPT 2009

Features Include:
* Surf the net in full PC lock out mode.
* Now with INSTANT POPUP BLOCKER - Blocks download prompts and many various popups.
* Added with extra blocks on shortcut keys - ie/ very limited keyboard access.
* Create admin password when prompted on script start or use previous password when cancelled.
* Toggle forward and back through web pages with mouse on screen edges and then left clicking mouse. ie/ To go back a page just take the mouse to the left edge of the screen and then a single left click, and to go forward, right side of screen and left click.
* To terminate press and hold down the Escape key for 3 seconds and you will be prompted for your password to exit which you have 10 seconds to comply - if you fail then wait 5 minutes to retry - this was added to prevent possible hack attacks.

BTW... When the script is executed please be aware that a small password file is created in its working directory, so you may like to place the script in a remote folder on your hard drive and create a shortcut to it on the desktop.
If you forget your password you cannot recover it from this file either... so dont forget it! Shocked

Hey mate!

Interesting idea!
I took your code for a test run, here's my experience (mainly concerning security):

- after doing a little stress test I was able to get the Win Key stuck on multiple occasions, so I could use Win+anything from then on (+r for Run for example)
- I'm pretty sure it can be done with any of the modifier keys
- ctrl+esc, and
- alt+space are working too.

in iexplorer:
- ctrl+enter/left click ctrl+shift+enter/left click to open links in new windows/tasb:
if you open a link in a new window, you get a window with all the menus, and url bar, and thus gain run/write access to all the files on the PC, and can easily kill the script or anything...
if you open a link in a new tab, you get access to various settings via the statusbar
- ctrl+l and ctrl+o to open files or new urls, full run/write access to the files on the PC
- ctrl+app key shift+f10 shift+app key to access context menu, and thus printing, saving files and pages to the PC etc.
-when download files, one gains access to virtually all the files on the PC via running the downloaded file or opening containing directory
- alt or shift + f1 opens help, and through help one gains access to the internet settings, via the local menu
- ctrl+F4 closes the iexplorer window
- and there's the possibility of gaining access to the PC through installed java or activex controls

I think I'd do a little more polishing on the GUI:D

I was testing it on Windows XP SP2 with Internet Explorer 6 on default settings.

Best regards and thanks for sharing:

You should add a timer to really avoid Task Manager Access, like that code I adapted once.

*Slight improvement on GUI aesthetics.

*Beeps added on password input confirmation and at end of 5 min wait if the password is incorrect.
*Tooltip gestures added.

Further details and changes are outlined in original post update.

You should add a few variables that people can modify

For example:
enable or disable browser
time allowed to input password
etc..
