Microsoft has released the KB5053656 update for Windows 11, addressing critical Remote Desktop Protocol (RDP) disconnection issues that have plagued users for months. This cumulative update, part of Microsoft's November 2023 Patch Tuesday, resolves multiple system stability problems while introducing several quality-of-life improvements.

The RDP Disconnection Problem

For several months, Windows 11 users reported frequent and unexpected disconnections when using Remote Desktop Protocol. The issues manifested in various scenarios:

  • Sessions dropping after exactly 60 seconds of inactivity
  • Random disconnections during active use
  • Complete session termination when transferring large files
  • Authentication failures after successful initial connection

Enterprise IT departments were particularly affected, as RDP serves as a critical tool for remote administration and support. Microsoft's official documentation acknowledged these issues, tracing them to authentication protocol handling and network stack implementation.
