Thread: Is XP professional 32- or 64-bit?

I want that whether XP professional 32 or 64 bit. Any help will be appreciated.

Windows XP Professional edition comes in 32-bit and 64-bit versions. If you plan to use the 64-bit version, you must have a 64-bit processor. However, you can still use the 32-bit version of XP Pro on a 64-bit machine.

As we know XP-64 bit Operating System processes faster speed than the 32 bit OS.

Windows XP Professional 64bit Edition is work with 64-bit processors from those which supports the x64 extensions.
The biggest difference between the 32 bit and 64 bit is memory addressing.
You should go for xp-64 bit or I recommend try Windows 7.
