Introduction

On October 15, 2024, Microsoft released the Windows 10 update KB5045594, also known as Build 19045.5070, as part of its ongoing initiative to harmonize user experience between Windows 10 and Windows 11. This update is significant not only because it addresses critical system stability issues—particularly those impacting users upgrading to Windows 11—but also because it brings fresh features and enhancements that reflect Windows 11's interface and functionality advancements.

Background and Context

Since the launch of Windows 11, many Windows 10 users upgrading their systems have encountered notable hurdles, including several Blue Screen of Death (BSOD) errors. These abrupt stop errors, particularly those with code 0x3B, have caused frustration among users due to disrupted workflows and upgrade interruptions. Microsoft has responded with targeted updates to smooth this transition and improve overall system reliability.

The KB5045594 update arrives as an optional cumulative update aimed primarily at Windows 10 version 22H2 users, serving to patch critical bugs while adding elements of Windows 11’s evolving design language and interface improvements.

Key Features and Enhancements

1. Stability and Bug Fixes

  • BSOD Fixes: The update corrects a race condition leading to stop error 0x3B during Windows 11 upgrades from Windows 10, greatly reducing upgrade failures due to sudden crashes.
  • Printer and Virtual Machine Fixes: Addresses issues with Multi-Function Printers (MFPs), particularly the printing of random network command texts over USB connections. It also resolves a critical stop error related to virtual machine switches using SR-IOV technology.
  • Scanner Driver Installation: Fixes problems that prevented scanner drivers from installing via USB, enhancing peripheral compatibility.

2. Start Menu and User Account Manager Updates

  • A revamped account manager integrates into the Start menu, enabling users to switch accounts more conveniently. This feature adds an ellipsis (...) next to the “Sign out” option and repositions the “Lock” command to the power menu, streamlining account management tasks.

3. Peripheral and Compatibility Improvements

  • WebView2 App Compatibility: Enhances recognition and functionality of devices like Xbox 360 controllers and Bluetooth peripherals that were previously unrecognized.
