Hello
I understand that you’re having trouble with your touchpad settings after downgrading from Windows 11 to Windows 10. You’ve already tried a number of solutions, which is great. Here are a few more suggestions that might help:
Windows Update: Ensure that your system is up-to-date with the latest patches and updates.
Device Manager: Press Windows key + X and go to Device Manager. Click Action and Scan for Hardware Changes. Check if the HID touchpad appears.
Touchpad Software: Some touchpad software installs a tab onto the Mouse properties box, usually the last one, that should have more settings to check.
Manufacturer’s Website: Visit Acer’s official website and look for any specific touchpad drivers for your Acer Predator PHN16-71 model.
Windows 10 Touchpad Settings: Go to Settings > Devices > Touchpad to check the settings.
Please remember to restart your computer after trying these solutions. If the issue persists, you may want to consider reaching out to Acer’s customer support for more specific assistance.
