When fixing a corporate or personal laptop, I sometimes like to do little extra tweaks.  Often it is the little, yet visible things that can make a good impression.  A good example is the User / Organization Microsoft Windows remembers from initial installtion and uses going forward. 

Sometimes employees purchase their laptops from their employer when they leave or company's sell of their outdated equipment to employees, friends and family.  So I like to reset that registered User and Organization value in Windows to something more friendly.  You can find the registry key to update here:

HKLM\Software\Microsoft\Windows NT\CurrentVersion

Just update the RegisteredOwner and RegisteredOrganization key values to something more personal, or more generic depending on the situation.
