How to change 32 bit to 86bit

I don't know how to change bits

There is no such thing as 86 bit. If you have a 32 bit operating system and want to use the 64 bit version, then you're going to have to do a complete reinstall with the 64 bit version of the operating system you wish to use. That's assuming your hardware supports 64 bit, though that really shouldn't be a problem unless your system is a low end netbook powered by an Intel Atom processor, or your system is more than 10 years old at this point.

FYI, x86 is 32bit. x64 is 64 bit.

But isn't x86_64 64 bit and not x64?

Your statement there, x86_64 is the same as x64.

x86 is the actual instruction set. However, x86 somewhat has a reference to 32 bit OS in mainstream operating systems. For example, when you look at a Windows Explore on a Windows x64 OS, you'll see two (2) "Program Files". One will just be "Program Files" the other will be "Program Files (x86)". 64bit programs will be installed in the regular "Program Files" folder while the 32 bit programs will be installed in the "Program Files (x86)".

x86 is the CPU architecture that defines all CPUs derived from the Intel 8086, which was Intels first commercially available 16-bit CPU. All PC based CPUs to this day are derived from this CPU, just with a ton of features added on top. The most notable are x86-32 (usually just shortened to X86 as 16-bit OS's have gone the way of the dodo) and x86-64/x64/AMD64, the 64-bit extension to the architecture that AMD introduced in its Athlon 64 lineup that Intel eventually adopted after it's own 64-bit solution (an entirely new CPU architecture, the Itanium) failed in the marketplace.

Anyway, to answer the OP, to move from 32-bit to 64-bit requires re-installing the OS, as the fundamental architectures are completely different.
