A summary of the procedure required under Windows 10:
As earlier messages in this thread make clear, thanks to RBS, it's possible to replace the X240/s clunkpad with the X250 Touchpad and make it work under Windows 10. This post is only a summary of previous posts, with a new download to make things even simpler.
After installing Windows 10 or the first time, or after Windows 10 upgrades itself to a new version, do this (you may need to do this more than once before the driver finally gets installed):
1. Download this patched driver (made using RBS's instructions) and extract it to a convenient directory:

2. Disable your wi-fi connection and remove any ethernet cable.
3. In the Windows device manager, under Mouse, select the Synaptics driver, choose update driver, and navigate to the WinWDF folder in folder where you extracted the driver. Click OK until the driver gets installed.
Note: If the driver won't install, then delete the Synaptics driver from Device Manager, restart your computer and try again from step 1.
4. In the Group Policy Editor, go to Computer Configuration -> Administrative Templates ->System -> Device Installation -> Device Installation Restrictions -> Prevent installation of devices that match any of these device IDs. Choose Enabled, then click the Show button, and enter these values on three lines:
Code: Select all
Click OK and exit the Group Policy Editor.
5. Restart your computer. See whether the Touchpad and TrackPoint are working correctly. If so, restart again to make sure they are still working. If they continue to work correctly, then you can now reconnect to the Internet. If not, repeat the procedure described above.
Please do not waste your valuable time posting a message complaining that this message merely repeats earlier posts. That is exactly what it is intended to do, in clear summary form.
