It's 7 years old try Vista
No. It is outdated, and was horrible in the first place. You could try Vista, but that will cost ya, and Ubuntu is far better and free.
get xp, do not get vista.
Yes, it's XP / Vista without all the "eye candy".

It's faster and has fewer bugs, but you'll still have to protect yourself from Malware.
It is out of date, but if it is working for you then keep using it! I have custemers that still use 2000 and love it!
