Notes on Windows Updates

If automatic updates enabled on your system, you should see the new updates in the next couple of days. Or, you can stay on top of things by manually heading to Settings > Update & Security > Microsoft Update to check.

Older versions of Windows 10 are getting updates today as well. Make sure to read the documentation on the Windows 10 Update History page for your version’s full release notes.

If something breaks after you install today’s updates and cannot be resolved by Microsoft’s documented workarounds you can roll them back.
