I bought Windows 95, 2000, xp, Vista (came with laptop) win 7 ... I dont expect getting Windows 9 or 10 for free tho.
I own WB 1.3 3.0. 3.1 3.9 and 4.1.
So Im going to gladly pay OS 4.1 FE. It equals a 2-3 pints of beer on a Saturday night.
Put the cost of the OS to what you spend on your day to day, its a laughable low sum of money.
