Don't you mean Windows PowerShell?
It would be nice if Microsoft would could simply make things simple AND NOT allow any update to one's computer which inserts itself into the startup or launch mode.
My issue looks like malicious code or malware. Odd that Windows 10 asks me every time if I want this application to make changes to my system except for this.
Make it simple folks... one place to see what is being launched at startup! I would add a log.
