Cryptographic Services (CryptSvc) Defaults in Windows 7

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.

Default Behavior

Cryptographic Services is a Win32 service. In Windows 7 it is starting automatically on the operating system startup. Then the Cryptographic Services is running as NT Authority\NetworkService in a shared process of svchost.exe. Other system components, such as drivers and services, may run in the same process. If Cryptographic Services fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the CryptSvc service is not running because of the error.

Dependencies

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.

Restore Default Startup Configuration for Cryptographic Services

2. Save the Win7_CryptSvc_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

4. Restart the computer.

The CryptSvc service is using the cryptsvc.dll file that is located in the %WinDir%\system32 folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 7 installation media.
