About this episode

Microsoft updated Windows 10 printing after June patches, but USB printers can duplicate as “Copy1,” breaking name-based printing; Microsoft’s workaround manually transfers ports. Office now resumes blocking remotely received VBA macros by default unless admins use policy or signed documents. Windows 11 also adds default RDP account lockout after ten failures.
