Well Microsoft has changed things again since my last post that showed you how to reset the start layout in Windows 10 1709. Now with 1809 there is a new key name and it does look to be slightly random so I am now having to use a wildcard. I’m currently only testing every other build so please keep me updated if this breaks with a spring feature upgrade release.

Remove-Item 'HKCU:\Software\Microsoft\Windows\CurrentVersion\CloudStore\Store\Cache\DefaultAccount\*$start.tilegrid$windows.data.curatedtilecollection.tilecollection'  -Force -Recurse
Get-Process Explorer | Stop-Process
