Too many User names ?

[Guest]

Vista Home Basic, D-E521, Question is, on the OS(C properties,security tab,
under the Group or User names, there are 4 of them, I am the only one that
uses this computer, 1, is Authenticated Users, and only the special
permissions is checked, 2, is SYSTEM and all but the spec permis. is checked,
3 is Administrators(Bobbi-PC)Administators checked the same as 2, and 4 is
Users(Bobbi-PC\Users, and read & execute, list folder content, and read, is
all that is checked on that one. can I get rid of some of them, if so which
ones, and how.
Thanks for any help.

That is quite normal. You should not attempt to change any of those
permissions, or delete any 'users', as they are essential for the running
of your system.

Ok, then is there some way to set one of them as the "default" one, everytime
i get on line to do stuff, sometimes I get the permission pop up, and other
times, I will be doing the same exact thing, and don't, and how do I switch
me over to the admin, because, I will go to r-click, and run as admin, and
tells me I don't have permission to do that , and other times it works just
fine, I am confused OH, and thank you for the quick response, I was really
sitting here pondering doing something stupid!!!
