Microsoft acknowledges the Windows 11 CPU-intensive issue.

According to Neowin , the Windows 11 Insider build released by Microsoft in June experienced high CPU usage when running certain services. This issue was first reported by user Leginmat90 via the Microsoft Community Forum on June 5th.

The issue is believed to be related to the Phone Link features that Microsoft is currently testing.

Leginmat90 later discovered that the Cross-Device Service was the cause of this Windows 11 Insider build suddenly using an unexpected amount of CPU. If this service is disabled, CPU usage will return to normal.

In response to the report, Microsoft engineer Jennifer G confirmed the issue and stated that the company was identifying the cause and working on a fix. However, a week after the report surfaced, Microsoft has still not been able to resolve the problem.

It is known that Cross-Device Service can help Windows 11 computers connect with other devices such as mobile phones to synchronize content, share files, etc., essentially supporting Windows' Phone Link feature. The recent Windows 11 Insider build is reportedly testing Phone Link-related functions, which could be the cause of the aforementioned issue.

Meanwhile, Windows 10 users don't need to worry about the aforementioned issues. What they should be concerned about is Microsoft's decision to end support for Windows 10 systems on October 14, 2025, leading some third-party companies to turn their backs on the operating system. For example, AMD has begun removing Windows 10 compatibility from some newer CPUs. Users are advised to consider upgrading their hardware and operating system as soon as possible.
