Microsoft has released the optional KB5052077 preview cumulative update for Windows 10 22H2, which includes nine bug fixes and enhancements, notably addressing an SSH connection issue acknowledged in November. This issue affects a limited number of devices on Windows enterprise, IoT, and education editions, with ongoing investigations into potential impacts on Windows Home or Pro editions. The update elevates Windows 10 22H2 systems to Build 19045.5555 and includes fixes for the Desktop Window Manager, Chinese IME responsiveness, and color contrast issues. Two known issues are associated with KB5052077: one involving Citrix components that may obstruct the installation of the January 2025 Windows security update, and another related to a System Guard Runtime Monitor Broker services issue generating 'Event 7023' errors. Over 60% of Windows systems globally still run on Windows 10, despite its approaching end of support, while certain Long-Term Servicing Channel and Long-Term Servicing Branch releases will continue to receive updates beyond October 2025.
