I accidentally deleted my domain name (or user name ) from what I thought was the administrator account on my computer and have been having problems with this terrible OS (Windows XP Home Edition) ever since.After reading so many different forums and postings everywhere you can imagine, I am led to believe that the account was actually the built-in administrator account as Windows XP Home edition does not have an administrator account. Please correct me if I am wrong.Now I no longer have administrator access nor can I make any changes or install any programs and I am extremely frustrated.My account is now showing as a guest account although all my files are still available. Thank goodness the files were shared (at least that's what HP told me) not sure if I believe all they said.When I ran net user to list all users on my computer, there was NO administrator account listed. I see my guest account, another account I have on the system with limited access, and four other files that don't make sense. I also tried to access the account from Safe mode several times and still do not see it.This is the information that was gathered from the net user command: User shows my "guest account name"; Full name is blank; Comment shows "Built-in account for administering the computer/domain"; Account active, "yes"; Local group membership, "Administrators"; Global group membership, "none".So, I did a search on the Internet looking for more answers and came across a website that listed a probable solution (something new) because I assumed it was a registry issue (something else HP advised, in addition to the OS being corrupt, when trying to add the administrator account) , which involved my going to HKEY_Classes_Root to check permissions for each user and possibly add permission for my supposedly administrator and guest account. So, I went into the registry under HKEY_Classes_Root to check users listed and found the following Group or user names:1. Administrators ("my computer name"\Administrator)2. Creator Owner - None3. System4. User ("my computer name"\users).So I followed the instructions and when it came to the part to "Find Now" I clicked on the button to find user accounts on my computer and found the following:Adminstrator - "My Computer Name"Guest (shows Red X)Guests (network)Help Assistant (shows Red X)Helpservers (network service)HP_Owner (remote interactive logon)"My Guest User Name" (service)"Other user name" (system)and some other user information.....not relevant.Now I have a virus on the "other user name account" that I cannot remove nor can I run my antivirus program because of the Administrator issue. I also tried to backup my files online and cannot do that because I cannot install any programs due to....yes, the Administrator issue.Can someone please, please tell me what can be done to resolve this issue? I am at my wits end. I do not believe it requires my removing, repairing, and reinstalling my entire OS. There has got to be solution to this problem. And I do hope it's not the same answers I keep reading in so many forums that seem to give the same answer over and over. I also apologize if I sound a little rude, but I am so very frustrated with this XP thing. I have had several computers and different OS systems, of which I have NEVER had any problems, but this XP thing is by far the worst I have ever seen in the history of my experiences with many computers.PLEASE HELP!!!!!!!!!!!!!!!!joaynn 2 people got this answerI do too
