Earlier today I was deploying a new WSUS server and found an interesting little bug. On Server 2012 R2 WSUS servers, Windows 10 client devices are listed as Windows Vista. Obviously from a patching and management point of view this could cause some problems. Luckily Microsoft has released a patch for Server 2012 and Server 2012 R2 to fix this issue.
To install the patch is the usual process. All you have to do is download the patch, double click on the installer, click next a few times and reboot the WSUS server. After the server comes back up, the Windows 10 client machines will show as Windows (Version 10) instead of Windows Vista.
