Hello 燕 刘,
I understand how disruptive it can be when a single click is intermittently registered as a double-click, especially after you have already tried several relevant troubleshooting steps.
Since the mouse works correctly on other computers and the behavior occurs with both wired and 2.4 GHz connections, could you please confirm:
Does the same behavior occur with a different mouse on this PC?
Did it begin only after installing build 26220.9202?
Does it happen throughout Windows, including the desktop and File Explorer, or only in certain applications?
Is any Huawei mouse software, macro utility, or input-remapping tool installed?
Testing another mouse on the affected PC would be especially helpful. If another mouse behaves the same way and the problem began after this build was installed, it may indicate an issue with the current Insider build or the PC’s input environment rather than the mouse itself.
Please also check for a newer build under Settings > Windows Update. If the behavior continues, press Win + F to report it through Feedback Hub. Include the build number, the troubleshooting already completed and a recording of the problem if possible. You can then share the Feedback Hub link here so others experiencing the same behavior can upvote it. Thank you so much for your understanding.
