Microsoft released two emergency updates to address related January issues. While they primarily target cloud storage and boot failures, they contain cumulative kernel stability improvements:

KB5077744: Released January 17 (specifically for 24H2/25H2 stability).

KB5078127: Released January 24 (targets unresponsive apps and Task Manager bugs).

These often must be downloaded manually from the Microsoft Update Catalog if they don't appear in your standard Windows Update list.

Thanks

Hey, both are included in February 10 update KB5077181 and that didn't help. More and more I am thinking it can be a configuration issue, January update KB5074109 maybe misconfigured something and even uninstalling that update didn't help back in January.
