+# Determining the Windows Update Service source
+
+Windows 10 devices can receive updates from a variety of sources, including Windows Update online, a Windows Server Update Services server, and others. To determine the source of Windows Updates currently being used on a device, follow these steps: 
+
+1.  Start Windows PowerShell as an administrator
+2.  Run  `\$MUSM = New-Object -ComObject   “Microsoft.Update.ServiceManager”`.
+3.  Run `\$MUSM.Services`. The resulting output should be similar to the following:
+
+```
