I cannot open Backup and Restore from the Control Panel, either under Backup and Restore or Action Center. The Backup and Restore application is working and makes backups as previously configured. However, I cannot open the application to check my settings. I don't understand how the application can continue to work as configured yet I'm not able to open it. I don't know when the problem started. I have an original Acronis backup saved from the time the computer was purchased in February of this year. It's a new Dell Studio XPS 7100 with factory installed Windows 7 Ultimate 64-bit. I don't particularly want to go back that far in restoring the system. I've run the sfc /scannow command to no avail. The problem occurs in all three user accounts, including the true Administrator account which is not used. The problem also occurs in Safe Mode. I doubt if I have a System Restore point going back far enough to regain the ability to open the Backup and Restore application. To the best of my knowledge I cannot use the OEM installation disk to repair the system files. My settings in Services are correct, the Backup and Restore being set to Manual and Started. Is there a way to check the Backup and Restore entries in the registry to determine if everything is as it should be? If so, where in the registry are the entries located and what are the entries and their values? I use Microsoft Security Essentials in real time and manually start Spybot S&D, Malwarebytes, Avira AntiVir and SUPERAntiSpyware on a periodic basis to further check for malware. No malware has been detected. I don't see any functions of any of the malware applications that would interfere with Backup and Restore. I'm not overly concerned about the problem since I use Acronis to create periodic backups. I simply wish to be able to open the Backup and Restore application. I've researched this problem for several days and have not been able to arrive at a solution. Thank you in advance for any assistance provided. C.B.
