The Microsoft Most Valuable Professional (MVP) Program was started in the mid 1990s as a way to recognise those members of the general public who devoted their time and considerable computing skills, on a voluntary basis, to helping users 'in distress' in the various newsgroups hosted by Microsoft. There are now around 1800 MVPs worldwide who actively participate in the Microsoft Technical Newsgroups. Many are IT consultants, some are published authors or technical instructors, and there are those who have no formal training but have an in-depth level of practical experience.

Do I have 32 or 64 Bit Windows XP?

Windows XP 64Bit Logo

This is a question which has been showing up on the Public Windows XP groups and elsewhere increasingly since the event of Worms such as MSBlast which needed a Windows hotfix. For the time being at least 64bit home computers are not that common, when systems feature an AMD Athlon 64 processors or a future Intel 64 Bit EM64T aware Pentium 4 ot Xeon the '64 Bit' status will be something highly advertised as a selling feature.

So the easiest way to tell is if you are running Windows XP – Home, Professional, Media Center or Tablet PC Edition version 2002 (or Media Center 2004) you have a 32bit version of Windows. At present the 64bit Editions of Windows are packaged with 64 Bit computers and the client versions are packaged with the name '64-Bit Edition' or 'x64 Professional' rather than just Home or Professional.
