then you are most likely aware of
the fact that your PC will have a
Product ID. This Product ID is a
system specific alphanumeric code
which is derived/calculated based
on the Windows product key you
use and the hardware configuration
of your Computer. In simple words,
Product ID is the alphanumericcode
that you see when you Right-Click
on the My Computer icon and select
the Properties option.
Ever wondered how
to alter the Windows
