Security Center (wscsvc) Service Defaults in Windows 7

The WSCSVC (Windows Security Center) service monitors and reports security health settings on the computer. The health settings include firewall (on/off), antivirus (on/off/out of date), antispyware (on/off/out of date), Windows Update (automatically/manually download and install updates), User Account Control (on/off), and Internet settings (recommended/not recommended). The service provides COM APIs for independent software vendors to register and record the state of their products to the Security Center service. The Action Center (AC) UI uses the service to provide systray alerts and a graphical view of the security health states in the AC control panel. Network Access Protection (NAP) uses the service to report the security health states of clients to the NAP Network Policy Server to make network quarantine decisions. The service also has a public API that allows external consumers to programmatically retrieve the aggregated security health state of the system.

Default Behavior

Security Center is a Win32 service. In Windows 7 it is starting automatically after the operating system is started. Then the Security Center service is running as NT AUTHORITY\LocalService in a shared process of svchost.exe. Other system components, such as drivers and services, may run in the same process. If Security Center 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 wscsvc service is not running because of the error.

Dependencies

Security Center is unable to start, if at least one of the following services is stopped or disabled:

Restore Default Startup Configuration for Security Center

Before you begin doing this, make sure that all the services on which Security Center depends are configured by default and function properly. See the list of dependencies above.

1. Run the Command Prompt as an administrator.

2. Copy the commands below, paste them into the command window and press ENTER:

sc config wscsvc start= delayed-auto
sc start wscsvc

3. Close the command window and restart the computer.

The wscsvc service is using the wscsvc.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.
