If the OEM tag is missing a reference to 64bit, is the installed OS 32bit? RRS feed

  • Question

  • I'm looking at an old Compaq computer that has an OEM tag for Windows Vista Home Premium.  There is no bit reference on the tag, does this mean that the computer came with a 32bit version of Vista?

  • The same Windows Vista product key can be used to install a 32-bit or a 64-bit version. There is no way to tell which bit version was actually installed by looking at the product key.
