The most obvious problem with June patches was a conflict between Microsoft’s latest version of Windows and Microsoft’s latest version of Office (er, Microsoft 365) Click-to-Run: If you installed patches as soon as they came out, Outlook wouldn’t run.

We also saw a bunch of belated patches for printers that didn’t work after installing the June Windows updates.
