Recommended - Temporary disable the Automatic Office Update & roll back the most recent Office updates 

MS July 2017 Updates crashed Q&A. In order to fix it it's needed to:

1. Turn OFF automatic updates in Office (under the "Account" settings / update options)
2. Close Excel and any other Office apps
3. Run the following commands as Administrator in Command Prompt (CMD)
cd "C:\Program Files\Common Files\microsoft shared\ClickToRun"
OfficeC2RClient.exe /update user updatetoversion=16.0.8229.2073

This issue seems to affect Current Update Channel - if the customers would like to stay safe of this they can use Deferred Channel instead

So far it seems that KB4011051 has caused the problem.
