Blocking HELP file access

Here's a process that might help:
(1) delete all *.hlp files on the pc
(2) delete all instances of winhelp.exe
(3) institute policies to prevent internet access
(4) remove access to DOS prompt
(5) set policies to prevent directory navigation
(6) get a firewall/router solution that allows complete lockdown of internet access without passwords

For XP/ME/2000. You don't say what OS you're using.
This restriction removes the Help option from the Start Menu.

Open your registry and find the key below. You may need to create the key if it does not already exist.

Create a new DWORD value, or modify the existing value, called 'NoSMHelp' and edit the value according to the settings below.

Exit your registry, you may need to restart or log out of Windows for the change to take effect.

(Default) REG_SZ (value not set)
NoSMHelp REG_DWORD 0x00000001 (1)

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\...

Registry Settings
User Key: [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\
Policies\Explorer]
System Key: [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
Policies\Explorer]
Value Name: NoSMHelp
Data Type: REG_DWORD
Value Data: (0 = disable restriction, 1 = enable restriction)

Using Win 9x. Deleting all help files is not an option as one of the apps uses it in the background.

Other classrooms can not be blocked from the Internet. Only need to block the ones where there is poor classroom management.

Fortress 101 does a good job of blocking most of what I need. I wish I could remove the HELP button as in 2000/XP

Do the students need access to resources elsewhere on the school network?

Seems like the simple solution would be to disconnect the classroom from the rest of the network. Unfortunately, with Win9x being an inherently unsecure operating system, there are only so many things you can do to lock down a comuter without relying on other software or physical measures.

I assume upgrading to Win2K Pro or XP are out of the question?
