Hi Leaker Xu,
As mentioned by AI answer, the behavior you’re seeing matches a known Windows Search issue on newer Windows 11 builds where the Search UI becomes unresponsive when typing. This is usually caused by a Search component glitch or a recent update regression, rather than a hardware or major system issue.
In addition to the suggested fix (Install the latest Windows updates and Restart the Windows Font Cache Service), you can try this check:
Restart the Search UI process for fast recovery:
- Open Task Manager, go to Details
- End:
SearchHost.exe - Windows will auto-restart it when you open Search again.
If you’re on an Insider / preview build, this can also be a temporary regression, and it may be resolved in a newer build.
