Windows 2000 and Windows XP are different, Windows XP was released
about 2 years after Windows 2000
Since the computer was bought at a garage sale and you do not have the
media, it is probable windows is not legitimate.
Is there a sticker "Certificate of authenticity" affixed to the
computer somewhere?
If not, Windows is most certainly illegitimate.
It is not uncommon for people to sell computers with illegitimate
Windows installed.
You may need to purchase Windows if you want to continue to use
Windows.
