I could go back to 7/22/2022, which is when I know my machine was working fine, where I don't have to reinstall all my programs. That was a system backup I made when I lost a hard drive that had all my virtual instruments on it, as I was upgrading from a spinning hard drive to a solid state drive for the operating system. However, I wonder if I would need sighted help to do this, as I'm sure it might take hours depending on what programs I need to reinstall, as some of them require sighted help to configure to the right settings.
You do not go back that far at all.
I am talking about a day, or a week or so.
System Restore Points are made on a regular basis, not every couple of years.
