Below about says it all. I tried SysRes from two points, both with same failure.
System Restore did not complete successfully. Your computer's system files and
settings were not changed.
System Restore failed while restoring the directory from the restore point.
An unspecified error occurred during System Restore. (0x80070091)
The two attempts were from: choose a different restore point>show more restore points type Backup. I really need this function to work. Any solutions out there?
