Which is the latest version of Windows XP Professional?

The Final Version OF Windows Xp is Windows Xp Service PAck 3 its loaded with lots of security features of that of Vista like NAP even msconfig is modified and mmc version is that of vista many bugs found on service pack 2 has been fixed in service pack 3 but nothing is perfect, even after you install service pack 3,you will still receive security updates. and you need little bit more amount of ram for service pack 3, but will work under 256 MB ram.

Ive recently installed SP3 and ive had no trouble at all with it. To be fai i dont even know what it updated as ive not noticed anything different.

Hi there Roop Money! I received my service pack 2 CD-ROM a couple of years ago. I forgot the site where I signed up to get it though.

That I know the latest version for Windows XP Professional is service pack 3. I have use it, it very stable and better than SP 2. This Service Pack 3 is been released many months ago.

Well, for me, Windows XP Service Pack 2 is still the best, cause, there are still bugs on SP3. So, i recommend SP2 rather than SP3.
