Was this post mis-quoting the operating system?
The article says 8.1 support is ending.
Does that mean 8.0 support?
Windows 8 support continues.
Windows 8.1 support continues if you keep installing upgrades as they are available. So far the upgrades are free, I don’t know if that will change.
What they mean is Windows 8.2 support is beginning.
However... Microsoft itself yanked Windows 8.1 Update from the corporate WSUS update server chute almost a week ago and still hasn't offered a replacement.
You have to UPDATE 8.1 to 8.1 Update 1 to continue to getting patches.
This is a monumentally poorly-written communication. They are forcing 8.1 users to go to Update 1 to continue patching. This is most likely a security update that is irreversible.
