Why is it "not believable"? All they have to do is pick up another 13% on the adoption rate from W7, and they weren't offering free upgrades in the first year then.
Business upgrades are not just about "Free" for any operating system upgrades. If any IT department made such a decision based on the fact that the OS was "free" I'd can the head of the department. Testing alone should take two years for most businesses to assure that the OS is compatible with their operations.
Where is the uptake of Windows 8 and 8.1 in business, Tacticalogic? It was released to manufacturing in August of 2012. . . How about the business uptake of Windows Vista?
Ummm, when Win7 appeared, companies were reeling from the horrific Vista experience.
Right now, the companies who will jump on Win10 are the ones reeling from the similar Win8 experience.
Those with Win7 are, by and large, quite content, and I predict they will stick with it for many years to come. I don't see 75% adoption in two years as likely at all. I think 50% would be a heck of an achievement in businesses.
I'm willing to bet $20 that they don't make 75%, decided by a reasonable average of industry acceptance monitors, two years from this July 29. Loser donates $20 to the contemporary FReepathon.

“Free Upgrade” to Windows 10 = Subscription.
Sorta like the free modem the cable companies offer.
W10 subscription takes ownership of several system services. If the subscription is not paid the computer loses significant online functionality.
