Why Does Windows 11 Keep Hiding My System Tray Icons? (Taskbar Icons Missing)

Solution:
Open PowerShell as Administrator and run the following command:

$RegistryPath = 'HKCU:\Control Panel\NotifyIconSettings'
$Name = 'IsPromoted'
$Value = '1'

Get-ChildItem -Path $RegistryPath -Recurse | ForEach-Object {
    New-ItemProperty -Path $_.PSPath -Name $Name -Value $Value -PropertyType DWORD -Force
}


This forces Windows to treat all tray icons as “promoted,” which makes them stay visible.
After running it, all your system tray icons should appear, even after a restart. Enjoy it!
