How to hide Windows tasks using PsExec

Deleting the task Security Descriptor will make the task invisible to any user in the system. Note that this requires PsExec!

1. Use PsExec64.exe -s -i regedit to open regedit with SYSTEM privileges.

2. Search in HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tree\ for the task to hide. Under the key for that task, there will be a value named SD that contains the security descriptor. Simply delete it.
