I screwed up my Registry. Please Help.

Guys,
Its 4:30 AM and I've screwed up my registry. I somehow managed to restore back the settings. One problem remains.

When you right click the start button, you see a context menu with entries such as

Explore
Find
Open

etc.

I deleted these for the reason that I had many of my own short cuts to my favorite programs there and it was getting

overcrowded so I thought I might as well delete the Open and Explore commands. My system wouldn't let me open any

folder or file. I've restored everything now. The only problem that remains is that when I open any folder in explorer

and then double click the folder to view its contents, instead of opening the sub folder, it shows the Find Files or

Folders dialog box. I am running a NT 4 box. After a trecherous battle, I figured out that this happened because the

Find command is currently the default (bold faced) command in the context menu of the Start Button. It should

actually be the Open command that must be the default one. If I am somehow able to restore the default button to

Open, I win the game. I have lots of work to do tonight. I've stayed up the whole night planning the object design and

am in the middle of writing a complicated message parsing program. Please does any soul know how to set the default

item in the Start Button context menu with the registry.

This question is not related to Visual Basic. I am sorry for putting it up here.

Guys, please don't bother. I fixed it.
