It would be nice to have a filter option to show 32-bit machines and 64-bit machines in the VSA.
The easiest way to filter this is with a View. Use the "Installed Applications" and filter on the splwow64.exe file. Make 2 views, one that says if it contains the file then its 64 bit and another that says if its missing then its 32. I would also pair this with OS Info and use the "OS Version Filter" with *build* as this will remove Mac and Linux since windows is really the only one that has the build in the os version info.
