In any case, here is the OneDrive link for AutoRuns and ProcMon Logs plus xperf trace: (Is there a way to reset PC 100 % back to factory configuration?) I reset my PC to factory configuration - except for a few minor settings such as desktop wallpaper, IE 11 homepage, etc. If possible, I would want to see PROCMON/XPERF/AUTORUNS traces on a clean system, which doesn't have any additional application installed but is still experiencing the issues. You've mentioned few times already that you've tried restoring the system and the issue still persists. I deactivated SkyDrive.exe as it seemed the cursor issue occured when SkyDrive made a TCP connection, but the cursor issue still continued.

Even though it might not relate to mouse, it might have some performance impact on the system. Skydrive process keeps reading HKCU\Software\Microsoft\Windows Services\Bici\Common registry key every few seconds.Cursor issue predates installation of Emsisoft Internet Security. Here's a2hooks32.dll module from Emsisoft AV inject in some of the processes and it might interact with the keyboard/mouse.Cursor issue predates activation of HydraVision.
