Wsus workstations not updating
Windows Server Update Services (WSUS) provides a convenient way to keep Windows servers and clients up to date as new updates are released by Microsoft.
Group Policy is the primary means of configuring machines in an Active Directory domain to download updates from WSUS and is the first thing that should be checked if machines aren't appearing in the WSUS console.
The WSUS Group Policy settings are stored in the same location as other Windows Update settings: Computer Configuration\Administrative Templates\Windows Components\Windows Update.
The WSUS management console provides an administrator with the ability to easily see which updates are available and which machines require them.
The administrator is also able to classify machines into different groups and select which updates will be available to which groups.
First off, as I know many of you are waiting with bated breath to get Windows 8.1 Update 1 installed, here's the just-updated KB Article that provides the fix for the WSUS issue that caused Microsoft to halt delivery: KB Article 2959977: Windows Update Client does not scan against WSUS 3.0 SP2 if HTTPS is configured and TLS 1.2 is not enabled Now, customers who centrally manage updates to clients using mechanisms that rely on WSUS technology can rejoice.
