Force WSUS to Synchronize Now from PowerShell

After passing my MS 70.410 exam I had a little bit of free time on my hands, so I thought I’d clean up my WSUS servers and prepare them for Windows 10 and VS 2015. So I thought I’d force myself to do the whole thing via PowerShell. The problem is that the UpdateServices PowerShell module doesn’t have cmdlets for some things I wanted to do -force a synchronization was among them. So I needed use the Microsoft.UpdateServices.NET components to perform these functions.

Useful Commands

To force a WSUS server to synchronize now:

[sourcecode language=“powershell”] (Get-WsusServer).GetSubscription().StartSynchronization() [/sourcecode]

To get the result of the last synchronization:

[sourcecode language=“powershell”] (Get-WsusServer).GetSubscription().GetLastSynchronizationInfo() [/sourcecode]

Pretty simple! I’m sure additional functions will crop up and I’ll try to post any useful ones here as well.
