Thanks to all for any help and or suggestions. In my case I just added myself with full control with special permissions.

In HKLM/Microsoft/Windows/Current/Version/Policies/Explorer in the link NoControlPanel, I changed the data value to 0 from 1. I found that somehow my registry was changed. And another person wrote:Got Control Panel Back and modify the key No Control Panel by exchanging the 1 for a 0 thus disabling the no in the control panel. To get back to the control panel follow the path as described before: Then check Apply repairs automatically and click Next. Step 3: Click Advanced in Hardware and Devices. Step 2: Go to Troubleshooting > Hardware and Sound > Hardware and Devices. Step 1: Open Control Panel and select Large icons from View by. I had to add me to the list with special permission.I read from other peoples comments that the problem could be the (0),(1) designation in the control panel configuration. You can try it when you have problems related to Realtek HD Audio Manager not opening. Evidently the computer did not recognize me as the administrator after changing the hard drive. I went into the registry and added myself in the permissions section with full control. The problem of not being able to view control panel was only in safe mode so I don't think it had to do with a start up problem.
