PART 2 Of- I Had A Computer Shop Rebuild My Wife's PC Due To HDD Failure

I had a computer shop rebuild my wifes computer. They built itunder the name RoB Davies.my name is RoD Davies. It . To "fix" this error, I added a User in Control
Panel/User Accounts uner the name Lenore and gave her admin rights and Deleted the User in Control PanleUser Accounts of Rob Davies or I THOUGHT I HAD.I then had to MANUALLY ADD the User "Lenore" to C:Users

However, in C:Users there is STILL RoB Davies with all folders (music,saved searches etc) of about 1gb in size and a User Lenore, same folders(music et al) of about 40KB. I have done some checking and all the Registry Keys are under Rob Davies.

THINKING BACK, perhaps instead of ADDING a User in Control Panel underLenore, maybe I CHANGED the name of the Account from Rob Davies to Lenore.If I did, perhaps Vista H/Premium DOES NOT amend the C:User (name) , itleaves the C:User as RoB Davies...if you get my drift. Which is why I had to manually add a Lenore to C:Users?

Is that possible? And what would therefore happen if I:

1. MANUALLY Deleted the C:UserLenore that I manually added.
2. Went to Control PanelUser Accounts and Added another User, say LDavieswith admin rights (which WOULD have VISTA create the User in C:Users as
C:UsersLDavies)
3. RENAME the account in Control PanelUser Accounts presently named Lenore BACK to RoB Davies and then
4. DELETE the User RoB Davies in Control PanelUser Accounts which thenmight Delete the User in C:UsersRob Davies
