Event details
If an organisation didn't meet the deadline or for example had some devices that didn't power up for a while. What is actually going to happen. It seems a very confusion scenario. I am also seeing ADKs and other ISOs still provided by Microsoft that have not been updated. Rufus is pretty keen to tell you that its not going to keep working.
Systems will still boot and apply the updates when they get powered up next time.
Also, there are no plans (outside of corporate environments that decide themselves to do so) to revoke old 2011 signed bootloaders soon, so your Rufus stick will still work except on those environments, or if you purchase a brand-new device that does not come with 2011 certificates any longer.
