When you install a new application, using MS Setup, a default Name and Company are shown, these values can be changed when the details have changed or are incorrect.
Start/Run/RegeditHKEY_CURRENT_USER\Software\Microsoft\MS Setup (ACME)\User Info
Value Name: DefName, DefCompanyData Type: REG_SZ (String Value)
Modify the two values named 'DefName' and 'DefCompany', and change the values to your current Name and Company respectively. The next time you install a program these new values will be used as the defaults instead. Note: This will not affect the registered names of existing applications, it only affects new installations.
