Answer: Check and Restore Default Startup Type for Cryptographic Services

Note. Make sure that the cryptsvc.dll file exists in the %WinDir%\system32 folder. If this file is missing you can try to restore it from your Windows 10 installation media.



Cryptographic Services is unable to start, if the Remote Procedure Call (RPC) service is stopped or disabled.

If Cryptographic Services is stopped, the Application Identity service fails to start and initialize.


Additional Information

The Cryptographic Services is running as NT Authority\NetworkService in a shared process of svchost.exe. Other services might run in the same process. If Cryptographic Services fails to start, the error is logged. Windows 10 startup proceeds, but a message box is displayed informing you that the CryptSvc service has failed to start.

This provides three 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; and Automatic Root Certificate Update Service, which retrieves root certificates from Windows Update and enable scenarios such as SSL. 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.
