Hi Enrique,
For us to resolve this problem, we may need to perform several troubleshooting steps. I noted that you did a fresh install of Windows on the Surface. Was it done using a recovery image? In case you did not use a recovery image, we may try this later on.
For now, please download and run the Surface Diagnostic Toolkit. This will get the latest driver and firmware updates on your device, and also check for possible software issues. For more information and to download the tool, go
here.
After running the Surface Diagnostic Toolkit, perform a forced shutdown then restart the Surface. While it is on and while the cursos is stuck, press the power button for 10 seconds or until the screen goes off. On your next restart, the Surface will be
able to apply the new updates and reload the software properly.
If there are no changes, let's check if this is a hardware issue. Boot into the Surface UEFI and check if the cursor will be stuck in this environment. To get to the UEFI, switch off your device. Once the Surface is completely off, press and hold the volume-up
button then press and release the power button. When you see the Surface logo, you can release the volume-up button. Using the touchpad, try to move around the UEFI screen. Observe if the cursor will get stuck. If it does get stuck, then the problem is related
to hardware. It would be best that you reach out to the Microsoft Support team or visit a
Microsoft Store with the Surface with you. They will be able to assist you regarding hardware problems.
If the cursor works fine in UEFI, then we would have to continue troubleshooting the software. Please update this post with your findings. I will be notified when you reply and I will get back to you the soonest I can so we can resolve the issue.
Regards.
