i have a pretty old lenovo ideapad running Windows 10 22H2 and this thing's annoying me, the fact that the synaptics driver is old and there's no PalmKms registry key to enable the touchpad while typing, and i have palm tracking set to low, the driver version is 7.5, here's msinfo32
EDIT : It turns out my fix didn't work it only worked on the login screen tho
