Cumulative Update for Windows 10 Download Hanging | KB3189866

Microsoft has recently released the Cumulative Update for Windows 10 Version 1607 (x64) which a lot of people have been having issues with.  The update is hanging when your workstation tries to download it.

Microsoft are currently looking into getting this resolved, but in the meantime, you can manually download this update from the following location:

http://go.microsoft.com/fwlink/?LinkID=116494&updateid=0405fe13-e4d5-4aff-8cf1-0500f5f673f7

Manually install the update, reboot and you’re good to go!

You may need to restart the Windows Update service once you’ve rebooted if it thinks that it’s still downloading the update.
