If you've acquired a used PC, you may have noticed the previous owner's name is implanted all over the computer. When a version of Windows is initially installed, the owner's name is chosen. After this point, one must enter the registry to change it. The process is slightly different for Windows Vista than it is for Windows XP. Learn the process for both operating systems.
Click on your start menu and select "Run." Type "regedit" to bring up the registry manager.
Click on the folder named "HKEY_Local_Machine." It should be near the top of the folder contents.
Choose "Software," and then "Microsoft." Select "Windows NT" from the Microsoft folder, and then select "Current Version."
Browse the contents on the right until you find the entry labeled "Registered Owner." Right-click the entry and select "Modify." Delete the old name under the space labeled "Value Name."
Type in your name, and then click "Ok." Close the registry editor to finish.
Click on the Windows icon at the lower-left part of your desktop. Type "regedit" into the search box.
Click on the "regedit" program in the search result section. Select "HKEY_Local_Machine," and then select "Software."
Choose "Microsoft," and then choose "Windows NT," then "Current Version."
Right-click the entry labeled "Registered Owner," select "Modify." Change the name in the "Value Data" field to your own. Click "Ok." Close the registry editor.
Be careful when working in the registry editor; follow the instructions closely. Modifying the registry in other ways could cause problems.
