If it's recently been upgraded or had an old pre-upgrade backup restored,
that's not a major surprise; and surely you won't have ben running mysql on a
win7 for several years :-)
In brief, mysql changed password encryptions between 4.1 and 5.0, for various
reasons. The old password scheme is still supported, but iird the default
setting for that in newer versions is off, yielding you the error you are
reporting.
Of course, if none of that is the case, you may have been hacked; but it seems
somehow strange that a hacker would bother to install oldstyle passwords.
The error message you provide also mentions the oldpasswd flag for PHP < 5.2 -
also worth looking at.
