Windows 10: turn off ads in File Explorer

Get Ads Out of File Explorer

You can get rid of these space-wasting suggestions by clicking the View > Options in File Explorer, then clicking the View tab in the window that appears. Scroll down to Show Sync Provider Notifications and uncheck that box. That should prevent ads from showing up in File Explorer again.

How do I get rid of ads in the bottom right corner of Windows 10?
If you see the gear icon straight off select that and disable the notification, if not then use the right arrow to move it to notification then open the notifications and select the gear icon. You should be able to cancel the pop up.
