** I finally got an earlier restore point to work and I am able to get the PC running. This has been 5 hours of agony and I am sorry if I violated site rules that was not my intention. I will live with this solution and recover data as best as I can. Thanks to the moderator for the earlier response to my first question. * I apologize for my earlier question and it seems I did not state my question clearly, that is my fault. I am unable to start my late wife's PC this morning. I have a message stating that the PC has a corrupted registry. I have run chkdsk /R and then tried to go back to a restore point of yesterday afternoon but the restore fails. The message suggests that I reset the system but I would like to know if there is an alternative to this option as I would like to avoid having to reinstall and reconfigure the software and apps on the PC? If I do choose the option of reset for the PC do I need to have a windows 10 disk? Her PC was not shipped with a system disk. Thank you.
