Change Owner Name and Computer Name in Registry

After a friend's husband died she told me that she would like to be able to do e-mail.  I brought the Compaq Presario with XP home and took it back to original factory settings.  I used her name (Helen) for the registered owner and also named the computer Helen.  After doing a lot of downloading of desktop wallpaper and geting everything I thought she might enjoy using, she decided she was too old to start using a computer (and she was right).  I inherited the computer and now I need to know how to get rid of all mentions of her name in the registry.  Rather than having to search and delete one item at a time is there perhaps a more simplified way of doing this?

I think you should download a Registry Editing tool like Registrar Lite(freeware).  Once you have that program installed, there is an option to do a search.  Enter the name and make sure the 'search in' field has 'Registry' highlighted in it.  Execute the search and that will give you a list of reg entries with the name in it.  Before changing anything, a rule of thumb would be to backup your system before editing the registy.  Let me know how this works out.  Good Luck

I am sure there are others on the web, but here are two links that have the registrar lite download available.
To change compute name:
Go to Control Panel>System>Computer Name>click on Change

You should create a new profile:
Go to Control Panel>User Accounts>Create a New Account
After that, delete Helen's account.

In addition to the suggestions made here;
You can change the 'Registered Owner' via editing the following key in the registry:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion]
Edit the following value names: RegisteredOwner, RegisteredOrganization

To use the registry you will need to be careful and do those modifications only;
1. Hit the 'Start' button.
2. Click on the 'Run...' option under the menu.
3. Type 'regedit' and press 'Enter'.
4. Go to the above branch using the left pane to navigate and change the propper values on the right pane.

Good luck

No sir,

You need to search for each occurence of her name and her organization in the registry.
Changing the "Registered Owner" does not change these values for other softwares.
But these are not hundred changes to do and you need to do it only once.

Changing the name and organization is a very simple matter and I have done that.  I have also deleted Helen from Users in Control Panel.  The difficult part is to get rid of Helen in the Registry.  Her folder remains in Explorer and elsewhere.  When I run Ad-aware and similar programs I see a lot of cookies with her name.  I will just have to take the time of finding all references to her in the registry and deleting them one at a time.  Thanks.
