lost application property

I tried to download a program file using IExplorer - big mistake.  I followed the help instruction that are with IExplorer so I could do this file download - even bigger mistake.  Following the instructions, I opened up file type, selected application and it edited my application properties, putting in the .exe file from the program I was downliading.  I got back most of the system but not all.  By putting the instruction where it asks for "application to perform the action"- C:\msdos\windows\system\command\start.exe - I can get programs to open (albeit they show a command window first and then the program opens).  I can not get things like the settings under my computer/control panel to open.  
When I go in file type, I need to know the "application that performs the action".  I have checked with others running Win95 and their systems won't even let them edit this file type, so I can't even see what this should be.  Can someone tell me what this should be and how I can protect it so I can't screw it up again.  PS I plan on using Netscape from now on.

1st,
You should follow the directions to the letter on:
How to Uninstall Internet Explorer 4.0
http://support.microsoft.com/support/kb/articles/Q174/2/65.asp
----EVEN IF YOU HAVE ALREADY UNINSTALLED IT.
Then we rebuild you system with [read following]
-----------
Re-install Using the "setup /p f" Switches
Reinstall Win95 from the command prompt using (setup /p f ) command. This will clean your system
files and replace missing and damaged files, without over-writing your updated dll's vxd's ext.
f -
This switch enables Clean Registry mode. It forces Detection to clean the root branch of the registry
before starting. This switch is ignored when Setup is run in the Windows 95 graphical user interface
(GUI). The default is disabled.
EXAMPLE:: setup /p f
As Always: Backup Your Registry First!
NOTE: The Setup /p f command does remove some commands that are pointing to the wrong
locations of programs and Win95 files, also does remove commands that are unknown to Win95
from the System.ini, Win.ini and the registry, but no promises can be given due to the nature of
Win95's individuality. So ALWAYS backup your registry and system files first.
/d -
If you do not want Setup to use your existing Windows configuration (such as your current Win.ini
and System.ini files), use this switch. To restore and adjust your windows installation try this: From
dos insert your CD and run from your cd this command...
EXAMPLE: setup /d /p f
When setup prompts you for "Full or Custom Setup", choose Custom. This allows you to have
control over every step of the setup. This will do a compare and replace missing or corrupted files
and will take you back where you were before the error.
