Apparently Microsoft has (sort of) replaced the \"Favorites\" Windows explorer item with the Quick Access item. But I haven\'t been able to find a way to programmatically ad
I like Johan's answer but I added a little bit to make not remove some of the items that were already in there. I had a ton pinned in there by accident I must have selected pin folder or something to quick access.
$QuickAccess = New-Object -ComObject shell.application
$okItems = @("Desktop","Downloads","Documents","Pictures","iCloud Photos","iCloud Drive","PhpstormProjects","Wallpapers 5","Videos", "Schedules for testing")
($QuickAccess.Namespace("shell:::{679f85cb-0220-4080-b29b-5540cc05aab6}").Items() | where {$_.name -notin $okItems}).InvokeVerb("unpinfromhome");
