Cryptographic Services (CryptSvc) Defaults in Windows 8

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.

Default Behavior

Cryptographic Services is a Win32 service. In Windows 8 it is starting automatically during the operating system startup. Then the Cryptographic Services runs as NT Authority\NetworkService in a process of svchost.exe, sharing it with other services. If Cryptographic Services fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the CryptSvc service hasn't been started.

Dependencies

Cryptographic Services can't start, if the Remote Procedure Call (RPC) service is disabled or not available.

If Cryptographic Services is disabled, the Application Identity service will not be started and initialized.

Restore Default Startup Configuration for Cryptographic Services

1. Select your Windows 8 edition and update pack, and then click Download.

2. Save the Win8_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 corrupted or deleted, you can put it back in there.
