Now question is : If we installed a database with user "A"(OS local Admin)? Can we upgrade the same database with user "B" (also OS local admin)?

That's not exactly what you said, but I just wanted to clarify ... while you DO have to be an account that is a member of the local "Administrators" group, it does NOT have to be a local account. A domain account will work as well, as long as that domain account is in the local "Admin" group. I am currently supporting 10.2 databases on Windows Server 2003, and use a domain account for all my work there.
You need to install the Oracle Database software using OS local Administrator.
You can not do all the maintenance with another user.
