If you're looking for a program that doesn't completely disable the Touchpad, just avoid accidentally changing the cursor position when your palm or wrist touches the Touchpad while typing, Touchfreeze is your software need.
Unlike TouchPad Blocker , Touchfreeze doesn't have many options but it works very well. Put simply, when Touchfreeze is running, it locks the Touchpad for a very small amount of time as soon as you press the key. This is an essential program if your work requires a lot of typing on the Laptop.
