I know that it seems to suck, but you just got a bad tech. A popup on
your screen will tell you exactly how many days you have to activate
or reactivate. Believe what your computer tells you, not some person
from a third world country.
I change hardware much more than others also. I have had to
reactivate about 4-5 times over the years because of this. My
situation is NOT the norm. Many, many people buy a computer and used
it until it dies, without even adding one additional program or piece
of hardware. They don't know that they can. They replace what may go
bad by sending the computer back to the manufacturer. What they
usually get is an exact replacement part.
Also, their computer may have, in fact, been activated by the
manufacturer or need no activation because of the way the
manufacturer installs the operating system on their computers. The
customer/user does not even know that the process exists.
You and I are different. I have learned to live with it and I am
certain that you can also. At most, it is a phone call of about 5
minutes.
