Cryptographic Services - CRYPTSVC.DLL
Cryptsvc.dll is a service provided by Microsoft as part of your Windows operating system. It provides three management services: Catalog Database Service, which confirms the signatures of Windows files; Protected Root Service, which adds and removes Trusted Root Certification Authority certificates from this computer; and Key Service, which helps enroll this computer for certificates. If this service is stopped, these management services will not function properly and any services that explicitly depend on it will fail to start. The default setting for this service is 'automatic'. We'd recommend leaving it in place.
