Q: What’s are the advantages of the 64-bit version of Windows 7?

The most frequently-cited advantage is that your operating system will have access to more than 4 gigabytes (GB) of memory (RAM). That’s a big deal for some. More available memory means being able to run more applications at the same time or being able to give memory-hungry applications more room in which to work. The result could be increased productivity, better overall system performance, and fewer memory-related glitches. Of course, to get these advantages, you’ll have to outfit your computer with more than 4 GB of RAM, which will increase overall system costs.

Those who have made the move successfully to 64-bit Windows 7 generally report few glitches other than having to overcome a minor learning curve. For instance, on 64-bit Windows 7 you’ll find two “program files” folders on your C drive: one is called “Program Files” and the other is named “Program Files (x86).” The latter is used to store 32-bit applications. You’ll probably find most of your programs installed into that folder, since most applications are still 32-bit. The other Program Files folder is reserved for 64-bit applications. At installation, you will not have to choose which Program Files folder receives the installation files. The operating system does this for you automatically.
