List of Windows 1.0 OEM releases

Despite the known fact that Windows 1.0 was quite a commercial failure, you'd be surprised to know how many OEMs shipped it with their hardware.

This ist is by no means exhaustive or complete, but it is a nice piece of trivia and goes to show Microsoft's marketting might back in the day. Some of the OEMs mentioned below already signed up for Windows when it was first announced in November 1983 and many more joined the cause despite constant delays and objectively better offerings from the competition. Please note that not all of these OEMs have actually shipped Windows with their machines, but they were at least considering it at some point, according to various sources. Confirmed OEMs (via available copies, screenshots, photos, etc.) are listed in bold.

  • ACT Apricot: known releases include 1.03 (ACT designations "VB1.03" and "VR1.03") for their XEN, XEN-i and XEN-i 386 machines, pre-release version supposedly ran on the Xi, versions for other models are also possible.
  • Ainsi: a french magazine article from May 1984 says they signed the contract to ship Windows 1.0.
  • Altos: a PC Mag article from June 1984 says they demonstrated a pre-release build on their machines at a technical seminar.
  • AT&T: according to period magazines, Windows 1.0 ran on the PC 6300 already in December 1984, though the availability of the final release is unknown. Version 1.03 added drivers for the 6300.

  • Columbia Data Products: a PC Mag article from June 1984 says they demonstrated a pre-release build on their machines at a technical seminar.
  • Compaq: no release by them is confirmed, though it seems quite possible, considering Compaq was an early MS-DOS adopter and later worked closely with Microsoft on Windows/386. Also mentioned in a PC Mag article from June 1984.

I'm sure there were also others I haven't come across yet, but even at this point, the list is rather impressive in my opinion. If you know of any others I haven't listed, please contact me and provide the relevant information, so that I may update the list if necessary. I do intend to have a look at each of the available releases eventually, once I finish with the Evolution of Windows 1.0 series of posts.
