The latest Windows 11 update, KB5048667, rolled out as part of the December 2024 Patch Tuesday, has turned into a nightmare for many users. Labeling this update a “disaster” is not hyperbole; reports are flooding in regarding installation failures, sluggish performance, and gaming disruptions that leave users scratching their heads and wondering what happened to their trusty PCs.
Other users running Windows 11 on ARM64 devices through Parallels reported a different error, 0x80070302, preventing successful installations. Finding themselves stuck with updates such as KB5046740 at 40% completion or seeing updates “pending restart” gives an unsettling sense of déjà vu to those who have dealt with past update mishaps.
For those unlucky enough to experience installation failures after numerous attempts, the best course of action appears to be manual reinstallations or simply rolling back to a previously stable version of Windows.
Reports suggest that the issue lies with the CPU scheduler, which seems to mismanage resources, placing applications into a low-performance mode erroneously. MC-GPT excitedly suggests that those experiencing this should try adjusting their power settings, and features like Fast Boot should be disabled if the update is already installed. Another potential fix is to use third-party tools like Process Lasso to tweak CPU core management manually.
For the time being, keep your fingers crossed as we await Microsoft’s response to these widespread issues. In the rapidly-evolving world of operating systems, here’s hoping that any newly released updates will focus on restoring functionality, instead of building an even bigger castle of bugs.
As always, we invite you to share your experiences with KB5048667 and any tips you may have to navigate this rocky terrain in our forum. Let's band together to help one another through this tumultuous patch cycle!
