Microsoft Windows 11 22H2 Fixes Issues With Audio, VPN, and Brightness

In the run-up to August Patch Day, Microsoft is releasing a new maintenance update for Windows 11 22H2. The (still) optional KB5028254 patch does not bring any new functions, but instead a large number of improvements and bug fixes – for VPN, audio, and brightness.

KB5028254: Early installation possible

With patch KB5028254, Microsoft upgrades Windows 11 22H2 to build 22621.2070. Tested in advance in the Insider channel, the update is still considered a preview and therefore optional. The download must therefore be initiated manually via the Windows update function. An automatic installation will take place on the upcoming patch day on August 8, 2023.

The innovations are the same as those of the update for Windows 11 21H2 that was released at the same time. These include issues with missing display and audio devices after hibernation and excessive ARP requests when using Virtual Private Networks (VPN). In addition, Microsoft optimizes the brightness settings and fixes bugs with widgets that unintentionally detach from the taskbar.

Below you will find the detailed patch notes of the latest Windows 11 22H2 update. In addition to the highlights mentioned at the beginning, the expansion of the handwriting software input panel (SIP), fixes for excessive power consumption of the Windows notification platform, and inconsistent reporting of the L2 cache on various processors stand out.

Highlights von Windows 11 22H2 Build 22621.2070

  • With this update, the brightness settings become more accurate.
  • This update fixes an issue affecting certain display and audio devices. They are missing after your system is restored from hibernation.
  • This update fixes an issue affecting widgets. They detach from the taskbar when you don’t expect them to.
  • This update resolves an issue affecting virtual private networks (VPN). There may be excessive ARP (Address Resolution Protocol) requests to the network gateway. This occurs when the VPN is on a wireless mesh network that uses an aggressive throttling algorithm. Because of this, network performance is poor.
