Distributing Windows 8.1 update with WSUS? Not so fast

Enterprises excited to get their hands on the latest Windows 8.1 improvements  — including features focused on easing keyboard-and-mouse usage — might have to wait a bit longer. Microsoft pulled the Windows 8.1 update released yesterday because of an issue with Windows Server Update Services.

According to a blog post from Microsoft detailing the issue, it needed a complex set of parameters for the update to cause problems. The scenario involves installing the latest update on the client machine and it checks against WSUS 3.2 running on Windows Server 2003 SP2, Windows Server 2003 R2 SP2, Windows Server 2008 SP2 or Windows Server 2008 R2 SP1. It will fail if those machines have HTTPS and Secure Sockets Layer are enabled, and if TLS 1.2 is not enabled.

Scans will fail if this happens, which prompted Microsoft to pull the update from WSUS. The easy workaround is to enable TLS or disable HTTPS.

The update is still available through other Windows Update channels, including MSDN and Windows Update Catalog, but Microsoft recommends delaying deployment until it releases a fix.
