Unless you have an Itanium, yes, you can run 32-bit Windows and all the 32-bit programs on it you would like. x64 processors (Athlon 64, Core 2 Duo, etc.) are fully backward-compatible. If you run the 64-bit version of Windows (which in the case of XP is not really recommended) it supports most 32-bit programs, though you will need to find compatible drivers for your hardware.
