They pulled the pin on me because I had re-installed on more than one
machine too frequently.
It's a myth that MS will "pull the plug" for installing too frequently.
There is no limit on the number of times one can install it.
The limitation also isn't gotten around by any timing: When you
activate, a snapshot of your hardware is taken and stored. If a later
activation turns out to give too different a snapshot, you're told to
call MS instead - you can't do it automatically online. Then after
failing the automated phone call, you can get a chance to explain why
things changed to an actual person; and may or may not be granted an
activation.
It's the machine they monitor, not anything else. And you cannot
activate without allowing that snapshot to be taken. Their software,
their rules; you only license it and are expected to use it on their
terms. So a timing difference isn't the answer. If you've activated
once adn try it with sufficiently different hardware, you'll have to try
to explain it to them or you will be refused. They can even end up
putting your key onto the pirated lists, in fact. Note that OEMware is
the hardest to do installs with; retail versions are more lenient but
you still won't be able to keep two machines activated at once.
