I've recently had some issues with my Dell Vostro laptop and Dell sent me out some OS discs to reinstall Windows 7 Ultimate SP1. I expected to get 64-bit discs in the mail, but instead received 32-bit.
So I called up Dell and asked what type of processor I have. The person on Dell's side said 32-bit. So I looked up my processor: Intel Core i3 CPU M370 @ 2.4GHz, and the documentation I found online says it's a 64-bit instruction set.
So I'm guessing it actually is 64-bit. Should I request new discs?
