It worked when I just upgraded to Windows 10 64 bits from Windows 8 64 bits, but now all gone.
1. Uninstall and ReInstall or Fix: all tried dozen times, no working.
2. All services are there running like ZOMBIES, but icon gone in Task area: as the attachment. And nothing (splash image, login process) seen when stating windows.

3. Launch by software shortcut: no working, nothing happened.
4. Mouse Function: totally dead, just like any other cheap mouse, controlled by Windows default mouse only.
5. Device Manager: Yes, mouse device seems nothing abnormal.
