- Addressed issue where if a user manually changes the system's time zone and doesn't log off or restart, the new time doesn't display on the Lockscreen clock.
- Addressed issue that impacted some Epson SIDM (Dot Matrix) and TM (POS) printers, which were failing to print on x86 and x64-based systems. This issue affects KB4048955.
