2017-08 update for Windows 10 Anniversary Update ("1607") breaks WSUS - FIXED
NOTE (Updated 30/08): Microsoft appear to have resolved this issue with a new update for WSUS as well, see here for details.
I previously blogged about how the 2017-08 update to Windows 10 ("1607" / Anniversary Update) broke WSUS (along with clearing out your update history.
Microsoft have now released KB4039396 which updates you to build 14393.1670 which claims to fix this issue with the note:
Addressed issue with WSUS update metadata processing that can cause some clients to time out with a 0x8024401c error.
They also note that this update does not restore your Update History, nor will it hide updates that have been un-hidden by the initial 2017-08 update.
