Hello dordi and welcome to Seven Forums.
As far as I know, if restore points are no longer showing they cannot be retrieved. You say you began experiencing problems after updating your 7 Pro. Were these the "Patch Tuesday" updates released on 4/9? If yes, one of those updates (KB 2823324) has since been pulled by Microsoft because it was causing problems. MS pulls & recommends uninstalling KB 2823324?
I'd try removing that one first and see if the problems are solved. If not, try removing the rest of the updates and then reinstall just one at a time. Reboot your computer after each install. Windows Update - Uninstall an Update
