How can I delete the apps without an uninstall button?

Settings → Apps → Installed apps → find app → “…” → Uninstall

In Admin PowerShell run:

Get-AppxPackage *ExactAppName* | Remove-AppxPackage
In Admin CMD run:

winget uninstall "App Name"
For MSI apps use Admin CMD:

msiexec /x {ProductCode}
As last resort use a portable uninstaller (e.g. Geek Uninstaller)
