  1. In today’s world, a lot of applications are written targeting both the 32-bit and/or the 64-bit platform….

  2. This blog aims at clarifying the issues which 32-bit developers might be having when they start migrating…

  3. Ajoy says:

    Is there any performance degradation in installing a 32 bit OS say Windows XP professional on a 64 bit processor machine?

    If so what/why?
