Businesses are just gonna LOVE this.... Hell, a lot of them just got ONTO Win7 in the last year or two....
Business will still use VL/Enterprise editions. Those systems aren’t OEM-Built, but deployed from an .iso or .wim. That shouldn’t be a problem. Moreover, big organizations create their own golden wim’s and send them to the OEM to deploy on the hardware they purchase, which will still continue.
Small businesses can still use retail .iso/wim, and FREE MDT to deploy.
Honestly, I never keep the OEM’s OS. Wipe and Load. Too often the OEM images are crapped up with offers, trials, and vendor junk. I prefer to get that off the device and field a more pristine system to the end user.
Eventually, Windows 7 will lose support. That will be in 2020. I used to remember telling people many years ago about Win XP lifecycle ending in 2014, and people bitched then, too. But you and I know that the technology changes, and the threats do too, and this is a war requiring new weapons periodically.
