hi, i want to buy windows 3.11 and iv looked on ebay and none have a serial key does windows 3.1 have a seril like win 95+ etc?
No, neither win 3.1 or 3.11 have serial number keys.
If you end up getting Windows for Workgroups 3.11 (the latest and most powerful of the 3.x series), please note that it will ask for a serial number during setup, but it does not actually require that you enter one.
what is product key in windows 3.1??
