Check with .NET if Windows Update is On

Is there a way to check .NET if Windows update is enabled?

I want users to each time they enter my application indicate that their computer may be at risk and give them a link to the Windows update site (or the Windows update application from the control panel).

Preferably, it should work on XP, Vista, and Windows 7. Maybe there is a registry key or even a better API?

First add the link to WUApiLib "C: \ windows \ system32 \ Wuapi.dll"

Then you can use this piece of code.

WUApiLib.AutomaticUpdatesClass auc = new WUApiLib.AutomaticUpdatesClass();
bool active = auc.ServiceEnabled;

MSDN: " ServiceEnabled , , ".

auc.Settings.NotificationLevel . http://msdn.microsoft.com/en-us/library/aa385806(VS.85).aspx

Michael Pendl’s answer didn’t work for me, but he gave me the information I needed for her to work:

WUApiLib.AutomaticUpdatesClass auc = new WUApiLib.AutomaticUpdatesClass();<br>
string notificationLevel = auc.Settings.NotificationLevel.ToString();<br><br>

The line notificationLevelwill vary depending on which option is selected in the Automatic Updates dialog box.
