Hi Peter, It seems the last repair tried to delete orphaned keys in "HKLM\COMPONENTS\Microsoft\Windows\CurrentVersion\Component Based Servicing\ComponentDetect\......" but I don't see the key "COMPONENTS" under HKLM. Instead, those keys intended to be deleted are under "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\ComponentDetect\". Please check.
