Super User has several questions asking how to check if they are running a 64-bit Operating System, and how to check if their CPU is 64-bit capable. 

The majority combine both questions into a single post, despite being two distinct issues with different solutions.

----------

Essentially, there seem to be two distinct questions being asked.

- How can I tell if my Operating System is 32-bit or 64-bit?
- How can I check if my CPU is 64-bit compatible?

**How should these questions be handled? Which ones should be closed as duplicates? Should a [canonical question][1] be chosen and tagged as [tag:community-faq]?**
