I still have the identical problem after fully cycling thru Recovery/Repai Drives/Surface Scan/Reboot sequence as suggested. This took about 12 hours and did not report finding any problems. After that running the optimization or registry scan stop at the same hkey location and report the same number of errors. However, FYI, a copy of System Mechanic is on the computer but not running as the security program.
I have left the optimization program running overnight and it greets me in the morning with the same hkey location and the same number of errots as when I went to bed.
Any suggestions will be appreciated.
