Most bugs in Microsoft’s June patches have been fixed; go ahead and patch
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. That bug got cleared up when Microsoft fixed Office a week later, even though Windows was to blame.
We also saw a bunch of belated patches for printers that didn’t work after installing the June Windows updates.
