Initial problem was Windows would not boot nor would it boot to safe mode. Finally was able to boot copying the backup registry to the main registry. (That was the only thing that worked. Still have a later registry backup available.)
Issues now are SFC/ Scannow - "Windows Resources Protection could not perform the requested operation." and Windows Update gives error message 80073712.
Trying to avoid a reinstall of Windows 7 by either trying to repair these files or an also try to import a different registry backup
