Hi Cong, I'm John, a fellow Microsoft user like you.
I understand how frustrating this situation must be. Unfortunately, it depends on your laptop's OEM (Original Equipment Manufacturer) whether they provide specific driver support for Windows 10 on your device. I checked the Lenovo support page, and it appears that the touchpad driver only supports Windows 11.
This likely means that your laptop is optimized for Windows 11, and you may not be able to use Windows 10 without encountering compatibility issues. I know it's tough to adjust to a new operating system, especially if you’re used to Windows 10.
If you have any questions about navigating Windows 11 or need help with specific features, feel free to ask. I’m here to help!
Regards, John J.D.
