A 64-bit operating system can directly address more memory. This makes it "better" if you have more memory than can be addressed in 32 bits ... 4 GB.
If you have 4 GB of RAM or less, there's essentially no difference, and the 32 bit system may even be slightly faster.
Most operating systems are designed for either 32-bit or 64bit CPU's.
32 is for 32 bit operating systems and 64 is for 64 bit operating systems. .. nothing to do with game play
In simple terms, 32-bit operating systems can only be able to run on 32-bit CPUs and 32-bit apps, but a 64-bit operating system can be able to run both 32-bit and 64-bit CPUs and apps.
Most 64-bit operating systems contain a 32-bit translation layer. Installing a 32-bit program is no different than installing a 64-bit one.
32-bit operating systems can only address as much as 4GB(2^32) of memory. 64-bit operating systems can address much more than 1TB(over 1000 GB). However, windows is limited as to amount of ram it can use, so people will have reasons to buy next system.
Programs written for 32-bit operating systems will run perfectly well on a 64-bit system.
Windows 9x
Internet Explorer comes preinstalled with all Windows Operating Systems. To upgrade it, you would go to Windows Update. If you have a 64 bit Operating System, you can not install a 32 bit version.
32 bit operating systems can only address 4GB of memory 64 bit operating systems can address 4 petabytes of memory(1 048 576 gigabytes).

You don't have to "do" anything. All general-purpose 64-bit operating systems will run 32-bit applications as well out of the box.
"32-bit" and "64-bit" refer to the capabilities of the operating system and processor to access RAM. 64-bit processors and operating systems only offer a major advantage if you have more than 4 GB of RAM available. Otherwise, they are the same in performance. Currently, 64-bit versions of Windows have fewer drivers available for hardware than the 32-bit ones, so if you did not purchase a system with it, you may have difficulties.
