I remember installing NSW2001 in 2001 and my was computer was much better fo without it. Now I thought it improved bcoz my comp config is better. No they made a new product which can make a p4 with 256mb ddr and 64mb agp on ati card crawl. After I installed I saw a no. of processes starting which are nsw's i confirmed from windows inspector. I can't even close them. The antivirus slows the comp down real bad. Is it my settings? I also remember after isntalling thats it. IF u want to get u r old performance back u have to format the hdd and reinstall windows. So put in ur views too.
