Windows pushes update with no internet?

IsItJustMe:

Unless it was some sort of delayed update that waited to install a week later.

IMO that’s the only plausible explanation.

Check :

• Event Viewer → Windows Logs → System (filter for “WindowsUpdateClient”)
• C:\Windows\WindowsUpdate.log (if it exists)

The fact that update history shows nothing since early April strongly suggests these weren’t new downloads from Microsoft servers, but rather local operations completing.
