I assume that doesn't prevent you from using it and installing software and drivers? Just because something stops being supported doesn't mean it should stop working as it did before.
If the policy is followed, it sounds like driver signing will stop working as it did before. Presumably drivers signed before a certain date will work, but drivers signed after that won't. Or something.
Sure, but that doesn't "prevent you from using it and installing software and drivers". You can still install previously signed drivers. You can even turn on unsigned driver installation and install unsigned drivers.
Nothing is really changing on the user's side. They might not get new drivers going forward if the company doesn't want to or can't pass HKL, but Windows 7 is out of support at this point. Windows 8 is still supported, to be fair, but I don't know of many people who actually run it; it's either 7 or 10.
