January 2024 Windows 11 KB5034204 Update: Major Fixes for Bluetooth Audio and 24 Other Issues. The January 2024 preview update for Windows 11, versions 22H2 and 23H2, has been released by Microsoft under the designation KB5034204. This update notably rectifies Bluetooth audio issues and addresses 24 other known problems. As a non-security, optional cumulative update, it offers a preview of improvements and fixes ahead of the February 2024 Patch Tuesday release.

Key fixes in this update include resolving a problem with Bluetooth Low Energy (LE) Audio earbuds losing sound during music streaming, and an issue where audio from Bluetooth phone calls does not route through the PC when calls are answered on the PC.

The update also tackles a deadlock issue that hinders the search functionality in the Start menu for some users, as well as a bug in the OpenType font driver that affects text rendering in third-party applications on certain hardware configurations.

To install this optional “C” update, users must select ‘Download and install’ after checking for updates in Settings > Windows Update. Alternatively, the KB5034204 update can be downloaded directly from the Microsoft Update Catalog for manual installation. More details on installing this update at home are available in a support document.

Other significant improvements in this update include:

  • Fixing an intermittent issue where the device becomes unresponsive post-installation of a print support app.
  •  Enhancing Windows reliability during power transitions to reduce stop error risks.
  •  Resolving an issue with 7-Zip files appearing empty in File Explorer.
  •  Addressing a BitLocker data-only encryption issue where a mobile device management (MDM) service might not receive accurate data due to specific policy settings in the BitLocker configuration service provider (CSP) node.
  •  Quarterly updates to the Windows Kernel Vulnerable Driver Blocklist file, DriverSiPolicy.p7b, to include drivers vulnerable to Bring Your Own Vulnerable Driver (BYOVD) attacks.

Microsoft also announced that Windows 11 22H2 will no longer receive optional, non-security preview releases after February 2024. However, cumulative monthly security updates will continue for this version, as well as for Windows 11 23H2 and Windows 10 22H2, which will receive both security and optional updates.

About the Author: Bernard Aybout

In the land of bytes and bits, a father of three sits, With a heart for tech and coding kits, in IT he never quits. At Magna's door, he took his stance, in Canada's wide expanse, At Karmax Heavy Stamping - Cosma's dance, he gave his career a chance. With a passion deep for teaching code, to the young minds he showed, The path where digital seeds are sowed, in critical thinking mode. But alas, not all was bright and fair, at Magna's lair, oh despair, Harassment, intimidation, a chilling air, made the workplace hard to bear. Management's maze and morale's dip, made our hero's spirit flip, In a demoralizing grip, his well-being began to slip. So he bid adieu to Magna's scene, from the division not so serene, Yet in tech, his interest keen, continues to inspire and convene.
