Percy, unless you've turned it off, click:
Start
Programs
Accessories
System Tools
System Restore

and follow the prompts.

This is usually quite successful and is normally undoable. Occasionally I've seen an "unable to restore" type message but I don't recall ever ending up with a broken machine. (I have a business in IT)
