Have you tried to go through this process here to create a system restore point and then recover from it? I assume this is what you mean when you say "Recovery".?

There is no function available. Every action results in "..registery error ... scheduled for delete...". I routinely set a restore point as soon as I booted the machine now not one action is permitted. All actions result in the same error message.
