Originally developed by Microsoft, Windows is a family of proprietary graphical operating systems. Its primary purpose is to provide a platform for running software and operating hardware attached to a computer. Windows has been updated over the years as processing chips and computer memory have gotten faster.
The first version of Windows was a graphical user interface (GUI) extension to MS-DOS. It allowed DOS users to browse and execute files in a virtual desktop. Windows 1 was released in November 1985.
In the early days, MS-DOS users had to type directory paths to access files. Microsoft was developing Windows to take over this role. Windows 1 also featured a graphical Start button, allowing users to select a program to start from the start menu.
Windows version 2 introduced the control panel, allowing users to configure system settings. It also introduced the ability to minimize windows and resize them. It also added the ability to use TrueType fonts.
Windows version 3 also introduced the ability to control MS-DOS programs by using a mouse. It was also the first version of Windows to be distributed on a CD-ROM. It took up 10 to 15MB of hard drive space and required about 1MB of RAM.
Windows version 4 was an attempt to further improve the system. It included the ability to launch applications as tiles in a grid. It also introduced handwriting recognition. It also included a browser ballot screen.
Windows version 7 introduced automatic window resizing. It also included a new browser and a digital personal assistant. It also had a more stable operating system than Windows XP. It also included various automated update and recovery tools.
