Last month, Microsoft confirmed that its latest version of Windows 11 gave many gamers a headache. The software giant said it was aware of a bug that led to the activation of GPU debugging, which is not intended for regular customers. This causes the user’s computer to experience slowness, lag, and jerkiness when playing different games.

Microsoft had to create a fence to block affected computers from updating to Windows 11 22H2 to keep the problem from spreading. Now, Microsoft says the issue has been resolved and the upgrade barrier has also been removed.
Microsoft says that users affected by the Windows 11 22H2 performance drop should install the latest cumulative update, released on December 14, 2022. This update KB5020044 fixes GPU debugging and restores lost performance.
To check and install the KB5020044 update, press Win + I to go to Settings then Windows Update. Here, click the Check for update button and then wait for the system to check for updates. When you see the update with the number KB5020044, click Download and install to proceed with the download and installation.
Previously, users could solve the problem by updating the game to the latest version. However, this solution does not guarantee 100% success with all games. Fortunately, we finally have a solution from Microsoft itself.
Windows 11 22H2 is the latest update that adds many new features and improvements, including improvements to the game. In addition, it also fixes some annoyances of the original Windows 11 version, providing a better user experience.
