This isn't a dig at you, but I do think for the sake of education, this should be clarified.
32-bit and 64-bit are both x86; x86 being the abbreviation for the Intel 8086 instruction set for CPUs (basically, a "langauge" that the CPU understands). Pretty much every Windows desktop and laptop on the planet (bar ones running Windows RT) uses an x86 CPU, regardless of whether it's 32bit or 64bit. 64bit simply allows for extra memory to be installed on a system (this is a gross and almost insulting simplification of 32bit vs. 64bit, but for the sake of brevity and ocassion, I'll leave it at that
The "more official" abbreviation for 32/64bit is x86-32 and x86-64 respectively, but these are an absolutely pain to type out everytime. So, for the sake of simplicity, people colloquially refer to 32-bit systems as x86, and 64-bit systems as x64.
