UK store, "LIDL" sells a "Silver Crest" graphics tablet and the software merely includes this as the driver is installed for XP. (Instructions say that Vista/7 already have the driver software included.)
evidently VisTablet also uses it...
if you disable or delete atwtusb.exe your input tablet wont work anymore,so leave it as is
apparently used also by my Vistab graphics tablet also (old one) Doesn't seem to cause any issues, I just always wondered what the file went to...
