from the doc: ' The new Microsoft XP program
suite - everyone knows them, no one likes their
product activation because it restricts the use of
a cd-key to a single installation. This keygen
computes random and virtually unique cd-keys for
either Office XP Pro or Windows XP Pro, which can
be used to install and *activate* these products
on a unlimited number of systems - without risking
to invalidate a patched version by a product
update ! It says compute and not generate because
it takes some time to verify, if a random cd-key
can be made valid (use the benchmark mode to check
how long that should take on your system).
Unfortunately can not every random cd-key be made
valid, so it usually needs more than one try to
compute a valid cd-key (chances are aboout 1 to
40). In general it takes about five to ten minutes
to come up with a usuable cd-key.'
