Microsoft would shoot themselves in the foot if current 10 users couldn't upgrade, don't think that would happen. Good info though!
I do agree with you gtspeck they shouldn't. I just wish I could fix my display flickering issue. I am going to give windows 10 one more try when the anniversary update comes out. I hope it is fixed by then.
I don't mean to be a bummer. Here is a couple of quotes from Windows lifecycle page.
Windows 10, released in July 2015 **** Updates are cumulative, with each update built upon all of the updates that preceded it. A device needs to install the latest update to remain supported. Updates may include new features, fixes (security and/or non-security), or a combination of both. Not all features in an update will work on all devices. A device may not be able to receive updates if the device hardware is incompatible, lacking current drivers, or otherwise outside of the Original Equipment Manufacturer’s (“OEM”) support period. Update availability may vary, for example by country, region, network connectivity, mobile operator (e.g., for cellular-capable devices), or hardware capabilities (including, e.g., free disk space
That in bold kinds of scares me, when and if I ever purchase a windows 10 computer. Buy a computer and it can't be updated.
what happens to PC's that have windows 8.1 and cant upgrade to 10, I have already run into that on several machines
Is it possible to clean-install 1607?
From the link provided in the OP:
If your computer runs Windows 10 now, it will run the anniversary update.This specification does not provide compatibility and certification requirements for devices and computers that run Windows 10 or implementation guidance for exceptional user experiences. Microsoft will provide this guidance in other documents at a later date.
Would people update to or clean-install 1607?
