Thanks nheel! With the synrmihid.sys filename, I found the uninstall log and saw which folders it removed: C:\Windows\System32\DriverStore\FileRepository\synpd.inf_x86_2eb3d2d060225d42 C:\Windows\System32\DriverStore\FileRepository\synrmihid.inf_x86_88828d18e9dfe331 C:\Windows\System32\DriverStore\FileRepository\synzkb.inf_x86_5fcfc71ac0321ae6 And for some reason, this forum places a space after "syn". If you have these folders, could you zip them and upload? They contain the .inf file and package needed to reinstall the driver. Last request! For your digitizer problems, did you try recalibrating the display under Tablet PC Settings in the control panel?
