Windows OS Versions

Version Description
Windows 95 Released in 1995, this version was the first operating system that did not require MS-DOS to be loaded first. It is unlikely that you will meet this version as the majority of the PCs loaded with this system will have been replaced.
Windows 98 Replaced Windows 95 and is still widely used on both home and office computers. A second version (Windows 98 second edition (98SE) was later released which, among other enhancements, allowed computers to share the same Internet connection. It also had the ability to connect multimedia peripherals like video capture cards. The key differences between the two versions are listed below.
