What is the differences between different Windows versions (95, NT4, 98, ME, 2000, and XP(Home and Professional))?
The biggest differences between these Windows versions are between the 9x series (95, 98, ME) and the NT series (NT4, 2000). The NT series are generally used by businesses, rather than home users. They offer more stability, but are usually less compatible with applications and hardware. The 9x series is the version for the home users. It is less stable usually, but offers compatibility with almost all applications and hardware. Windows XP is between the two, offering the stability and features of Windows NT series, but the compatibility of 9x series (although there are a few hardware and software incompatibilities still.) There are two versions of XP, Home and Professional. Home is meant for the average home user, while Professional is meant more for businesses and power users.
