Options in KB-000045818 Don't exist

The instructions don't tell you in what product you're supposed to find the option. We have Endpoint Protection and it doesn't exist. So either it wasn't written to guide to to the actual solution or it's not for Endpoint Protection, which is where I would expect something pertaining to MS Office to be.
