For those, like me, with non-Wacom devices (mostly N-trig based devices like Sony Vaio, Surface and others), there is a way to make the pen work on Windows 10: Just install Wintab drivers for Surface from Microsoft on the link below.
ATTENTION: After clicking the red “download” button, the only file you need to download is one of the two at the bottom of the list, named “Wintab_x32_1.0.0.20.zip” or “Wintab_x64_1.0.0.20”, just chose the one which matches your system (32 or 64 bits).
