cd key 32bit or 64bit

[jayulzvern]

Is there a way from strictly looking at the key itself to tell if the key is for 64 or 32bit version of win 7 ultimate?

The key works for 32 or 64 bit but only 1 at a time.

A product key works for x86 and x64.

If its a single use code (i.e. pre-built computer bought from store), you can only have one computer running with that code.

If you have a multi-use code, you can have as many computers running as the code supports.

NO.

The key is the same.
