www.BlackViper.com: Windows XP Service Pack 2 Services 411 - Cryptographic Services

Cryptographic Services

Default Description:

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. If this service is disabled, any services that explicitly depend on it will fail to start.

Additional Information:

Mainly, it confirms signatures of Windows files. You may always get a dialog box complaining about uncertified drivers if this is disabled. This service is required for Windows Update to function in manual and automatic mode and this service is required to install Service Pack 1 and 2 unified updates and DirectX 9.0c. Windows Media Player and future .NET applications may also require this service for some "features" to function. This service uses about 1.9 MB of memory.

Take note: Manual updates via Windows Update Version 6 web site still requires Automatic Updates, Cryptographic Services, Background Intelligent Transfer Service, and Event Log to be running. Place all three, plus Automatic Updates, in automatic if you do not wish to update manually. In addition, I recommend that you change the default time of 3AM, for the automatic checking of updates, to a time when the system is "normally" on.
