Why does StartMenuExperienceHost want to wake my computer?

This ( linked to this ) worked for me :

Finally I cracked it! While looking for things to try, I stumbled into Microsoft community discussion System keeps waking. ShellExperienceHost.exe. Build 17074. There one of the suggestions was to check the Local Group Policy. There is Computer Configuration > Administrative Templates > Windows Components > Windows Updates > Enabling Windows Update Power Management to automatically wake up the system to install scheduled updates. Setting it to Disabled makes the difference!

I spend almost week solving the problem of StartMenuExperienceHost_cw5n1h2txyewy is randomly starting my computer. And the solution was super easy. Open Windows Start menu and remove any automatically generated icons (weather, photos thumbnails, games etc.). After restart, this job disappeared from powercfg /waketimers.
