On this day, exactly 30 years ago, Microsoft introduced the Windows 3.0 operating system, which included the legendary solitaire game Solitaire, which won the hearts of tens of millions of users around the world. And although Windows 3.0 was, in fact, just a graphical shell for MS-DOS, in just a couple of years it scattered with an unprecedented circulation of more than 10 million copies.
The system requirements of the operating system were very modest by today's standards. Windows 3.0 required an Intel 8086/8088 processor or better, 1 MB of RAM, and a whopping 6,5 MB of free disk space. The operating system was installed only on top of MS-DOS, refusing to work with any other DOS-compatible OS. Despite the fact that Windows 3.0 officially required 6,5 MB of disk space, users managed to install it on 1,7 MB floppy disks and run it on computers without a hard drive.
The successor to the legendary operating system was Windows 3.1, which was released in April 1992 and included more features that we are used to seeing in modern Microsoft operating systems, such as TrueType fonts, built-in antivirus, and later support for Win32 applications.
