Enabling Google Chrome as a protected application

Once all of your endpoints are updated, Google Chrome can be manually added back as an exploit protection application:

1. Go to Settings > Policies.
2. Click on a policy.
3. On the left, select Protection settings. 
4. Under Exploit protection, click Advanced settings.
5. Click Manage protected applications.
6. Toggle on Google Chrome (and plug-ins) and click Close.
7. Click Save.
8. Repeat steps 3-7 for any other policies as required.

We will automatically re-enable this setting at a later time if it is not manually completed.
