I've been researching this topic about Windows Genuine Advantage for some time and I haven't found anything conclusive. My question is: how important is WGA? Does getting all the updates really protect your computer even though one has all the necessary Anti-viral, spyware and malware installed. I'll bet there are thousands out there surfing the net with Windows 98 who haven't had an update on over 10 years. In another 2 months MS will no longer be doing anything with Windows XP. Does this mean that we will be less protected. A friend gave me her old computer which is running XP. I went on-line to check if it was validated and it wasn't yet she was on-line every day. I ran all kind of checks and there were only a few tracking cookies on it. This is why I started to question WGA. Please give my your input.
