How can I take screenshots in games and Win XP?

[jaffa]

Just wanted to know how I can take screenshots of games and Win XP.
What kind of software should I use?
Any freeware?
Should I think of anything particular when doing it (to make it as good as possible)?

for games that do not have a built-in screenshot taker, use fraps. (google this).


for win xp, hit your Print Screen button, then open Paint and Edit-> Paste.
