Thanks

Unless you ordered or installed x64, then your pc is most likely 32bit. Also check under System Properties.

I think he's asking if his computer would handle a 32-bit or 64-bit version of the upcoming Vista. CPU-z is the easiest way to find out what your CPU supports.

The second one is definitely x64 (64-bit) because of the dual-core. The first one, however, is a Pentium 4 and I highly doubt P4's are 64-bit.

EDIT: If you want to see if any of those computers can run a certain Windows Vista version, use this: http://www.microsoft.com/windowsvista/getready/upgradeadvisor/default.mspx

If one of those computers has built-in graphic chipsets, you may not be able to run the Aero desktop display with Windows Vista. Just run the check and you'll see what your computer can handle.

I think some P4s are 64-bit and some aren't. Download CPU-Z and check if it says x86-64/AMD64/EMT64 or whatever; or figure out the model of your cpu and check Intel's website.
