Users of Windows 11 24H2 are reporting significant performance issues following the installation of two recent updates, specifically KB5050094 and KB5051987. The problems seem to primarily affect systems using Intel’s latest Core Ultra 9 285K processors.
Many users have experienced game crashes and system slowdowns after applying these updates. Reports indicate that applications may throttle dramatically when minimized, leading to decreased CPU clock rates and overall performance. This issue has been confirmed across various applications, including 7Zip and Prime95.
One user noted that the performance in 7Zip’s benchmark was halved when the program was minimized. The user also found that distributing workloads across all 24 cores of the Intel Core Ultra 9 285K did not resolve the performance drop.
No definitive fix has been released yet; however, a temporary workaround involves adjusting power settings to maximize CPU performance in background processes. Interestingly, similar issues have not been reported with AMD’s Ryzen 9 9950X or older Intel processors like the Core i9-12900K, suggesting that the problems may be specific to Intel’s latest LGA 1851 platform.
Users experiencing these issues may consider reverting to a previous version of Windows 11 or reinstalling the operating system until a stable solution is provided. This update adds to the growing list of problems reported with Windows 11, including high CPU utilization and interface glitches.
