Cryptographic Services - Windows 7 Service
Provides four management services Catalog Database Service, which confirms the signatures of Windows files and allows new programs to be installed; Protected Root Service, which adds and removes Trusted Root Certification Authority certificates from your computer; Automatic Root Certificate Update Service, which retrieves root certificates from Windows Update and enable scenarios such as SSL; and Key Service, which helps enroll your computer for certificates. If this service is stopped, these management services will not function properly. If this service is disabled, any services that explicitly depend on it will fail to start.
This service also exists in Windows 10, 11, 8, Vista and XP.

Windows 7 startup should proceed, but a message box is displayed informing you that the CryptSvc service has failed to start.
