Microsoft has finally fixed a problem in the Windows 11 22H2 update that was causing sluggish performance for certain games and apps. 

On Tuesday, the company released the fix through a preview release dubbed KB5020044. In the release notes, Microsoft mentions that the update “addresses an issue that affects some games and applications. This issue is related to GPU performance debugging features. This lowers the expected game performance.” 

Redmond first alerted users about the bug on Nov. 10 in a support page. For some reason, the Windows 11 22H2 update can trigger additional debugging software processes while gaming, which can result in a performance drop, including stuttering.  

The company has not explained the exact cause of the error or what specific games are affected. But the issue was serious enough for Microsoft to halt releasing the Windows 11 22H2 update to affected devices when uptake of the operating system remains relatively low. According to Steam’s hardware survey, only 23% of gamers on the platform have adopted Windows 11. Meanwhile, Windows 10 dominates with a nearly 69% share. 

It was only on Nov. 22 when the company began partially removing the block on rolling out the Windows 11 release to target a smaller number of affected devices. Specifically, Microsoft said: "The safeguard hold ... has been updated to only safeguard Windows devices which have one of the small subset of games and apps which are still affected by this issue." 

Users on Windows 11 22H2 can download the fix as an optional update. This involves going to Settings > Update & Security > Windows Update. In the Optional updates section, there should be a link to download and install the update. The KB5020044 preview release also contains a host of other bug fixes and improvements to speed up performance.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
