I am using a Dell desktop with Win 7. I partitioned the drive and installed Win 8 upgraded to 8.1 as well. Everything on the Win 7 part works fine but on Win 8 part it allows me to create a restore point but if I change to Win 7 then back to Win 8 the restore point has gone and the max setting is back to zero. I tried all the things suggested in a previous thread by Brink but to no avail
