Fair enough, they warn you when signing up to the Microsoft Insider Program that there will be issues, that’s why we’ve downloaded it. We want to see what breaks.
Microsoft is counting on bugs to happen and has provided an Insider Hub launcher in the new Start Menu.
I’ll be honest, I’ve had to use this button more than once.
The 1st issue that I ran in to was a broken PC Settings launcher, I looked up a fix that had applied to a similar problem in early builds of Windows 8.1 and gave it a try. Start Menu, type CMD. In the Command Prompt copy and paste these instructions.
Powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRoot\ImmersiveControlPanel\AppxManifest.xml
Hit enter and restart, problem solved.
