To enable the Windows Update service for automatic startup and start the service:

  1. On the Network Access Protection (NAP) client computer, click Start, click Run, type services.msc, and then press ENTER.
  2. In the console tree, double-click Windows Update.
  3. In the Windows Update Properties window, next to Startup type, choose Automatic.
  4. Under Service status, click Start.
  5. If the service has been started successfully, the service status will be displayed as Started. Click OK.

Verify

To use WSUS, the Windows Update service must be running and configured to contact an available WSUS server.

To verify that the Windows Update service is running:

  1. On the NAP client computer, click Start, point to All Programs, click Accessories, and then click Command Prompt.
  2. In the command window, type net start, and then press ENTER.
  3. In the command output, under These Windows services are started, verify that Windows Update appears.

To verify the WSUS server configuration:

  1. On the NAP client computer, click Start, point to All Programs, click Accessories, and then click Command Prompt.
  2. In the command window, type reg query "HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate" /s, and then press ENTER.
