To allow WSUS (and presumably SCCM) for support for Windows anniversary, Microsoft released a patch last month which blew up  A number of WSUS servers.  They has now released KB3159706 which are supposed to fix, problem and support Windows anniversary. This patch installs on WSUS servers through the normal Windows Update process so even if you is not running Windows ten or  Care for anniversary, you'll receive that patch. The problem is so it REQUIRES a number of MANUAL steps to complete the install and if you don ' t, your WSUS console would Not launch.

You can read https://support.microsoft.com/en-us/kb/3159706 and https://blogs.technet.microsoft.com/wsus/2016/05/05 /the-long-term-fix-for-kb3148812-issues/for full details But it boils down to:

1. Run a patch cycle on the server this host your WSUS, reboot and then ensure that KB3159706 is installed
2. From a elevated command prompt run: "C:\Program files\update services\tools\wsusutil.exe" postinstall/servicing this tak Es than a few seconds to complete.
3. SERVER MANAGER > ROLES & FEATURES >. NET FRAMEWORK 4.5 FEATURES > Add HTTP ACTIVATION
4. Restart WSUS SERVICE
5. Launch the WSUS console and all should is well
   • If you is using SSL on the WSUS need to read the bottom of KB3159706
   • If you check for your WSUS > OPTIONS > Products and classifications, upgrades should now be listed and function correctl Y
