BEIJING, April 10 (Xinhuanet) -- Microsoft has temporarily suspended the rollout of Windows 8.1 Update 1 for business computers after discovering a Windows Server Update Services (WSUS) problem that prevents scanning for future updates.
The problem only shows up if a client PC has Windows 8.1 Update KB 2919355 installed and then attempts to scan against WSUS 3.2 while running on Windows Server 2003 SP2, 2003 R2 SP2, 2008 SP2, or 2008 R2 SP1.
It also only affects systems where HTTPS and SSL are enabled, while TLS 1.2 is not enabled on the server.
Some workarounds for those who have already deployed the update include disabling HTTPS on WSUS or enabling TLS 1.2. These can be changed back when Microsoft releases a fix.
