Windows 7 RegisteredOwner – Registry Hack

Windows 7 Registry – RegisteredOwner and RegisteredOrganizationRegisteredOwner Registry Value Windows 7

When you buy a machine with Windows 7 pre-installed, sometimes OEM’s leave their name in your copy of Windows 7.  A little research reveals that such names are stored in registry values called: RegisteredOwner and RegisteredOrganization.  Here is a registry hack to edit the value to reflect your organization. 

As a bonus, I have an amusing story featuring Evans Twp and his experience of RegisteredOwner.

To see what I am talking about call for ‘winver’.  In Windows 7, click in the Start Search dialog box, and then type: winver.

Key Points for RegisteredOwner  Registry Hack

  • Is RegisteredOwner a value in HKCU** or HKLM? 
    Answer: HKLM
  • Do you have to add a value, or modify an existing setting? 
    Answer: Modify
  • Is it a String Value or a DWORD? 
    Answer: String (REG_SZ).
  • Do you need to Restart, or merely Logoff / Logon?  
    Answer: neither, just type ‘Winver’ in Windows 7’s Start Search dialog box.

** HKLM is an abbreviation of HKEY_LOCAL_MACHINE, and HKCU is shorthand for HKEY_CURRENT_USER.  These acronyms are so well-known that you can even use them in .reg files, Windows 7 will understand and obey the registry instruction.

PowerShell Method for Modifying RegisteredOwner


  1. Naturally, you should backup the registry before experimenting, or at least export the Microsoft ‘Branch’ as a .reg file.
  2. If I were you, I would change ‘-value Guido’ to reflect your name!

$RegKey ="HKLM:\Software\Microsoft\Windows NT\CurrentVersion\"
set-ItemProperty -path $RegKey -name RegisteredOwner  -value Guido

Note 1:  You may wish to append this line to the above code:
get-ItemProperty -path $RegKey -name RegisteredOwner

Note 2:  You could modify the above registry hack to change a sister key: RegisteredOrganization.

Note 3: You can see more examples of PowerShell registry editing here.

The Story of Evans Twp and RegisteredOwner

In my homeland of Wales, Twp (pronounced Tupp) means a stupid person. The IT manager of a company I was working with was called Evans, and in common with many mangers, he was not very IT literate.  Consequently, one of the techies, Dai ‘eighteen months’, nicknamed this manager: Evans Twp. (Dai lost part of an ear in a Rugby scrum, and as a result, he only had an ear and a half!).

The IT department took on a new lad called Peter.  Practical jokes are often part of the initiation ritual for new workers, and this company was no exception.  Peter’s first job was to install five new Windows 7 Machines.  During the scripted set-up he discovered the Organization Menu; he stopped and asked Dai ‘eighteen months’ what he should enter. Dai said, "Put Evans Twp in the box".

When Peter proudly showed off the new computers he was taken aback when Mr Evans went ballistic and accused Peter of undermining his authority.  What happened was Mr Evans typed Winver in the Start Search menu, and saw that the ‘Registered To’ was: – Evans Twp. (Meaning: Evans the stupid one!)

I was visiting the company doing other work, when I heard of Peter’s distress.  Mr Evans told the poor lad that had to come in at the weekend and reinstall the machines, Mr Evans wanted the company name to display as the ‘Registered Owner’.  I took Peter aside and showed him how to launch Regedit and find RegisteredOwner. We found Evans Twp and changed it to the name of the company.  Peter was thrilled as it only took a moment to make the registry hack, and Peter went to the rugby match instead of sacrificing his weekend to perform re-installs.
