Undo Home Networking Wizard in XP?

Search is down, sorry if this is a repeat.

I was feeling ambitious today and tried to setup a home network for my desktop and two laptops over the wireless network today. Long story short of it, I decided the effort wasn’t worth it. My question is, I already ran the Home Network Setup wizard on my desktop and now there is a shared folder in My Computer and my printer is shared. If I want to get rid of this stuff, short of system restore or manually undoing everything, is there a quick way to shut off all sharing on the computer?

Right-click each item, select Sharing, and disable the share.

I figured that’s what I’d probably have to do. Thanks.
