Overview

Anyone on Windows 10 can follow this procedure or use this to recover autostart if an S6 unit is not auto-starting HS4. Note that User Account Control (UAC) in Windows may request permission to run programs, which would prevent HS4 from starting correctly without your interaction. If you run into such an issue, you will want to reduce or disable UAC on your PC.
