Well, with only one user, I always use the Administrator account (the proper one) on my PCs, and if it isn't already available without safe mode, then I make it so. For example, my latest laptop came with this account readily available on the login screen without sfae mode, so there was very little to be gained by creating another account with my name.
Move all the docs that you want to keep, being careful to keep the right versions of course, into the Admin account's docs folder. This is in the usual place (C:\Administrator\Documents and Settings\) then make this account accessible in the normal manner - ie without safe mode - from the User Accounts control panel utility. Then delete both the named accounts and you'll be ready to create a new named account if you wish, or just use the admin account.
