Touchpads in laptops are not for everyone, one of the first things to do when a I get a new computer is to plug a mouse and disable the touchpad (TP).
Few weeks ago, I noticed a strange behavior, in my laptop, every time I started a session in Windows, the touchpad was enabled, that is to say it did not keep its previous status. The touchpad is a Synaptics SMBus TouchPad. As this behavior was annoying, something needed to be done.
After some research I came across this wonderful solution where the touchpad is automatically disabled when a mouse is detected. Unfortunately, the Steelseris Keyboard in my laptop is detected as keyboard-mouse combo, then, the auto-disable, would permanently disable the touchpad, without option to enable it and who knows it could be useful (someday).

Later, after diving in Windows Register, with Regedit, I noticed a value, in two keys, that controls the touchpad's behavior at the beginning of the Windows session:
DisableDeviceUntilSessionEnd
in
HKEY_CURRENT_USER\SOFTWARE\Synaptics\SynTP\TouchPadPS2TM3163
HKEY_CURRENT_USER\SOFTWARE\Synaptics\SynTP\TouchPadSMB2cTM3163
Basically, when they are 0
the touchpad remembers its state at the moment of the last logout, and when 1
, the touchpad will be enabled every login.
Changing the values from 1
to 0
was the solution, to keep the touchpad disable.
In case you're want to the same re-enabling behaviour in the touchpad, edit the above-mentioned values in the Registry. You can learn the basics on editing the Windows Registry here: Learn How to Use the Windows Registry Editor (Regedit) in One Easy Lesson.
