What version of Windows did you install?

What is the make/model # of your computer?

You can use either CPU-Z or Speccy to take the guess work out for you.

Either of these programs, especially Speccy, will help you in correctly identifying what OS (and kernel version) you are using.

There is no way to change from one to the other interchangeably unfortunately

I'm guessing you have a 64 bit processor but a 32 bit OS. The only way to convert the OS to 64 bit is to do a complete reinstall.

No you're confused.

Yes the pc may have a 64 bit dual core processor.
But you in fact have a 32 bit version of windows.

A 32 bit version of windows will run fine on a 64 bit processor, it just will not use the extra core of the cpu. You would have to install a 64 bit version of windows to be able to use both cores of the Cpu by the os.

What are you talking about? There is no magical cpu core that can only be acccessed by a 64 bit kernel.

32-bit Windows will use all of your CPU cores, what it can't do is use more than 4GB (actually 3.25GB) of main memory. A 64-bit version of Windows can support more memory than that.

The only way to switch from 32-bit to 64-bit is via a clean (a.k.a. custom) install. There is no upgrade (or downgrade for that matter) path from one version to the other.

You can use the same product key that you used to install the 32-bit version, however.
