Looks like it might belong to my UC-Logic Digitiser Tablet WP5540
It appears to have been installed when I installed a UC Logic 3D graphics tablet

when i loock on the msconfig i saw this name on startup but when i searched for this file i can't see
Removing it only removed the useless clutter from my taskbar. My UC-Logic Tablet works just fine. Disabled in Run dxdiag startup uncheck Wservice.exe.
is for manhattan graphics tablet
Same as above
It's there since i installed a UC logic (target) pentablet

It was running on a system that had no tablet display, along with a process called syspools.exe, they were both were executing the virus and utilizing 99% resources. Do a virus scan, stop the processes, find the files and delete them.

28672 size, I have Genius MousePen, so it's likely a related driver.
Now I've seen another link at the same site hat confirms the WService as a valid program. The catch seems to be the uppercase athe the first letters in the good file. the bad file is called wservice, all lower case, and it is described different: updater, or something. So you gotta see which one is yours.

It is also used with Genius digitizers

Best practices for resolving WService issues

A clean and tidy computer is the key requirement for avoiding problems with WService. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the WService.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
