I changed my username long ago for my Windows 7 computer, but one outstanding issue is some applications still know me by my old username. A quick registry search found the name under

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\RegisteredOwner

I found my old username under several other program-specific registry keys as well. If I change my "RegisteredOwner" key to my current username, will this have negative consequences on other applications that already have their own copy of "RegisteredOwner"?

The "Registered owner" is unrelated to any account's real name or username, except by coincidence (which would be reasonable to happen on a home computer with one human user)!

Its only apparent purpose is to customize Windows's own About boxes (as seen with winver.exe), the System control panel applet (WinKey+Pause), and to provide a default for other programs which have an independent setting for an equivalent string...
