Q: I received a Windows feature update that I wasn't expecting. Where did this come from?

Answer

You may have received a Windows 10 feature update (e.g. Windows 10 v1809) that was NOT approved in MIT's WAUS. This can happen if you go into your Update Settings and click "Check online for updates from Microsoft Update" instead of clicking "Check for Updates". By choosing to look for updates directly from Microsoft, you bypass the approved patches from MIT. This is the Windows 10 feature known as Dual Scan.
