Retro Operating Systems

This page will contain download links and setup guides for vintage operating systems.

WinWorldPC is a primary source to safely download old versions of Windows (up until XP). Reportedly, Microsoft had once sent them a takedown request for Windows XP (only), but apparently didn’t care about older versions like Windows 98 or 3.1, so I also host mirrors of them locally on this site as well.

Windows for Workgroups 3.11

Windows 3.1 actually was just a graphical desktop shell that ran on top of MS-DOS, so links below will include where to get both MS-DOS and Windows (for Workgroups) 3.1x.

MS-DOS 6.22

The latest version of MS-DOS which works best for Windows 3.1 and Windows for Workgroups 3.11.

Download links:

• WinWorldPC: MS-DOS 6.22^https
• Archive.org: MS-DOS 6.22^https
• Kirsle.net: MS-DOS 6.22^https

Locally hosted mirror:

• MS-DOS 6.22 Floppy Images (.zip with 3 floppy .img, 3.5 MiB)

• MS-DOS 6.22 ISO (.iso image, 4.0 MiB)

  This ISO has the contents of all 3 floppy disks in one place. Note: CD images may not be directly bootable, but with a DOS boot disk and CD-ROM driver you could install it from ISO and save yourself a little disk juggling without needing to swap out the three floppy disks like normal.

Windows for Workgroups 3.11

This is the latest & “best” edition of Windows 3.11. Windows for Workgroups was designed, as its name suggests, for network connectivity support and joining a Windows workgroup network or connecting to the Internet using TCP/IP.

Download links:

• WinWorldPC: Windows 3.11^https
• Kirsle.net: Windows 3.11^https

Locally hosted mirror:

• WfW 3.11 Floppy Images (.zip with 8 floppy .img, 10.3 MiB)
