Have you ever tried troubleshooting a failed task sequence and when you try to navigate the logs you realize you have no mouse? It’s very frustrating.. Here’s the fix. Add a ‘Run Command Line’ step to your task sequence after the computer has booted into full OS. For the command use this:
REG Add HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System /v EnableCursorSuppression /t REG_DWORD /d 0 /f
Voila, no more mouse derps.
Credit to my man Tim O. for finding this one.
