On a regular basis, people ask me questions about changing user information, the information you provided when you installed Windows. You can change it. Both of the following values are in the key
HKLM\SOFTWARE\Microsoft\Windows NT\ CurrentVersion
>>RegisteredOrganization.
The name of the organization (Change this to your desired organization)
>>RegisteredOwner. The name of the user (Change this to your desired name)
These changes are reflected in the system instantaneously and requies no reboot.You can confirm this by seeing the system properties(Right-Click on “My Computer” icon and select properties).
Both are REG_SZ values. Changing the registered organization and owner names doesn’t affect installed applications. However, applications that you install after changing these values are likely to pick up the new names.
