- Search for and delete the following keys if found
HKEY_CLASSES_ROOT\Installer\Products\{Cb Defense GUID}
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Products\{Cb Defense GUID}
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Group Policy\AppMgmt\{Cb Defense GUID}
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CbDefenseWSC
- Search for additional registry keys
- HKEY_CLASSES_ROOT\Installer\Products
- Search for "confer" (no speech marks)
- Delete keys found in that path
Additional Notes
- Some registry key deletions may fail due to permissions
- It may be necessary to take ownership of the registry key by changing ownership from System to the logged in administrator account
- PS Exec (from SysInternals suite) can also be used to launch registry edit in order to delete keys owned by System
