Windows Updates - Troubleshooting Why Devices Are Still Auto Updating

Windows Updates is still auto-updating my devices against Automox group settings

If your devices are still receiving automatic updates from Windows Updates, even when this is disabled in your group settings, try checking the applied group policies. 

One of the easiest ways to do this is to check in RSoP. You can find instructions here: How to use RSOP to Inspect Applied GPO Settings

You can also run gpresult /h to generate an HTML file that you can read to see which GPOs are being applied or filtered for a computer or user.
