Using 32-bit key on 64-bit Windows

So, I have a notebook with a Windows operating system pre-installed. The thing is the version installed is a Windows Vista Professional 32-bit. The CPU is a Core 2 Duo. The default memory is a mere 1GB but with an additional slot for expansion purposes. Now, I think why I'm saddled with 1GB. Why can't I upgrade the memory all the way to 4GB?

But wait, didn't they say you couldn't take advantage of the 4GB memory if your OS isn't a 64-bit? That's still true but if you don't mind the extra work, why not reformat your unit with a 64-bit version of Windows Vista?

Can't activate Antivirus

Every once in a while, you are faced with a vexing problem where you try all sorts of solutions only to find that the most effective was so fiendishly simple, you wonder why you didn't even try it first.

I have a client who bought a McAfee Antivirus Plus product and we were tasked with installing and updating it into his laptop. Installing is a snap and the laptop more than meets the system requirements of the Antivirus. As with many retail software these days, you have to register and activate the Antivirus in order for it to work beyond the grace period given to you. This is where the problem came in.
