ph_ly Thanks for that. The closest I could find after searching for number of keywords is:
<policy name="L_PreventBingInstall" class="Machine" displayName="$(string.L_PreventBingInstall)" explainText="$(string.L_PreventBingInstallExplain)" key="software\policies\microsoft\office\16.0\common\officeupdate" valueName="preventbinginstall">
<parentCategory ref="L_Updates" />
<supportedOn ref="windows:SUPPORTED_Windows7" />
<enabledValue>
<decimal value="1" />
</enabledValue>
<disabledValue>
<decimal value="0" />
</disabledValue>
</policy>
But surely I wouldn't need to push out a registry change when the GP download was supposed to list it plainly. I am just wondering if this is an issue that only I am having.
Edit: To clarify, I am not seeing a setting called 'Prevent Bing install' anywhere. Hopefully this is just me being stupid and someone can point out what I am doing wrong.
