Windows 11 KB5064081 update clears up CPU usage metrics in Task Manager
Microsoft has released the KB5064081 preview cumulative update for Windows 11 24H2, which includes thirty-six new features or changes, with many gradually rolling out. These updates include new Recall features and a new way of displaying CPU usage in Task Manager.
The KB5064081 update is part of the company’s optional non-security preview update schedule, which releases updates at the end of each month to test new fixes and features coming to the next month’s Patch Tuesday.
Unlike regular Patch Tuesday cumulative updates, monthly non-security preview updates do not include security updates and are optional.

Microsoft says recent Windows update didn’t kill your SSD
Microsoft has found no link between the August 2025 KB5063878 security update and customer reports of failure and data corruption issues affecting solid-state drives (SSDs) and hard disk drives (HDDs).
Redmond first told BleepingComputer last week that it is aware of users reporting SSD failures after installing this month’s Windows 11 24H2 security update.
In a subsequent service alert seen by BleepingComputer, Redmond said that it was unable to reproduce the issue on up-to-date systems and began collecting user reports with additional details from those affected.
