There are currently two versions of Microsoft Windows 7 , a 32 bit version and also a 64 bit version.  The two versions differ primarily in performance and security, with the 64 bit version coming out on top between the two flavors.  The Windows 7 64 bit version supports up to 128 gigabytes of random access memory (Ram), while the 32 bit version of Windows 7 can only address up to 4 gigabytes of ram. Windows 7 64 bit also performs better, especially with applications that were written to take advantage of it. The downsides of the 64 bit version of Windows include the fact that it can’t run 16 bit applications, while the 32 bit version still can support them in part. That’s not really an issue though since legacy 16 bit programs are rare these days. The 64 bit version of Windows 7 also requires all device drivers to be digitally signed by the developer, while the 32 bit version of Windows 7 does not have this requirement.

In this tutorial we will show you a quick way to determine what version of Windows 7 you have installed.
