I used 2000 for over 6 yrs both at home and at work, and I never had any of the issues you had.

2000 was the most stable systems MS have made to date, thats why it was the best. And SP4 sorted out 99% of the problems. No one will ever create a 100% secure OS. It will never happen, thx to the worlds pool of reverse engineers.

TBH u sound like one of the many MS haters out there lol.
