I have determined that Norton is preventing my Windows 10 PC from from going into sleep mode. This is a fresh install of Windows 10 and NS 22.6.0.142.
Here's what powercfg -requests shows:
SYSTEM:
[SERVICE] \Device\HarddiskVolume6\Program Files (x86)\Norton Security\Engine\22.6.0.142\ns.exe (NS)
Does anybody have a solution to this?
