Re: Close, but still no cigar @Paul Crawford
But why only Win10?
I mean all of the major browsers like Chrome, Firefox and the also-ran Opera (sadly now a skinned Chrome engine) manage to support various versions of Windows and also Mac & Linux. Why can't MS do this?
Like Eric mentioned, they're trying to sell a new version of Windows.
I'd like to point out that this business model isn't unusual for all commercial operating systems. Older RHEL, OSX, Androids et. al. can/could be made to run the latest browsers and other software too. Whether it is trivial - I don't know. I know Android isn't exactly commercial but my Android 4.0 devices are without love - the burden is just with the device mfgrs unlike with other systems.
Since consumers and many small businesses are allowed to upgrade Win7/8 to Windows 10 this is not a problem for them. Same with OSX users who can upgrade to Yosemite.
Some may wish not to upgrade for several reasons including amount of work, incompatibilities, certifications and so on but that applies to all the other operating systems too.
