I recently get forced to update my current version from version 1709 to 1803..
after I post my issue with windows 10 fall creator
now I found the stable solution and it solve my problem. with this command' reg add HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Pen /v LegacyPenInteractionModel /t '
But once the spring update hit my PC and forced me to update it.. the pen scrolling came back and it solved by the same command .
however ... here is another problem that made me mad with windows 10 spring update, again :(
the pen flicks tab in 'pen and touch' window is disappeared. and there is no way to disable it ..
and because this is the final version from windows ... I hope I found way to bring pen flicks option back or disable it
Note: it is not hardware problem ... so, and solution for reinstalling the driver is not the answer.
