I can't move cursor while pressing a key

I recently upgraded Windows 8.1 to Windows 10.0. I have tried reinstalling Synaptics, removing and uninstalling Synaptics, disabling palmcheck, but it wouldn't work. It's annoying when you are playing a game that requires moving while pressing keys on your keyboard. I also have Synaptics 7.5 (19.0.10). The only way I can move my mouse while pressing any key is pressing (any key) + shift. Any ideas or suggestions would be highly appreciated.

I have the same issue, palmcheck is disabled and I've searched for other things but can't find any, halp!

Simply rollback your touchpad drivers to a version where this issue isn't a thing. That's what I did with synaptics, I had to update it to upgrade to windows 10, a few hours ago I finally figured it out, because I was tired of playing games the way I did, JUST ROLLBACK the tocuh-pad driver. I was probably as annoyed as you were, but then it became simple, THIS WASN'T an ISSUE until I INSTALLED THE LATEST touchpad driver xD. Hope this helps anyone else who has this problem.
