Vista - Upgrade Processor

Can I change my processor from a dual core to a quad core on
a motherboard that supports quad core running vista 64 ultimate
without having to re-install the my OS? Also, will replacing the
CPU trigger a call to Microsoft to revalidate. I'm thinking of
replacing my Intel E6600 dual core with an Intel Q9550
quad core.

AMD CPU's twice and Vista was fine with it. The new CPU was recognized and
no reactivation was required. One change was from dual core to quad, and one
was quad to quad.

Note: this is with retail Vista, not OEM.

Why do you want to do this?
I would certainly rather have 2 3300 processors then 4 2490 processors since
so that individual programs can run faster and I have no requirement to run
4 programs or program threads concurently.

Yes you can. Vista should sort itself out and you should not have to
reinstall or reactivate. Just simply shut down, change CPU and heatsink,
make sure everything is connected (take the opportunity to do a good clean
out!!!), turn on the PC and sit back for a few minutes. Any new drivers
required, Vista will go get by itself.
