You are right about that. I remember I turned on system restore and it helped me ages ago when I was had changed a registry then had to update windows and I had usb problems. I managed to restore back, change the registry back, then update and everything went good again.
Why would they have the system restore set to off by default? I don't understand that.
For me the reason why I was doing a restore was because I was trying out PS4 Remote Play app that beams the ps4 screen on to windows. I was reluctant to put a ps4 controller in to the pc but it worked. Then when I shut that program down and unplugged the controller, I thought I better check it hasnt messed up my steam xbox one controller setup. I plugged the xbox one controller in and loaded up steam. It immediately acted like it was a new device and all the controls it had previously automatically setup had gone. So I was trying to restore back to the point before I installed PS4 Remote Play. I actually made a restore point for that purpose.
