title: How common are 32-bit Windows installations as of now?
body: <p>I've noticed many programs are still released with 32-bit binaries or even only a 32-bit binary. How common are 32-bit systems? i.e., how many 32-bit vs. 64-bit systems are out there?</p>
  <p>This is important to help decide whether to continue shipping 32-bit versions of software.</p>
