Get-ChildItem HKLM:\SOFTWARE\Classes\CLSID | ForEach-Object {
	$regKey = $_;
	if ($regKey.GetValue('OLEDB_SERVICES') -ne $null -and $regKey.OpenSubKey("OLE DB Provider") -ne $null) {
		New-Object PSObject -Property @{
			'Key' = $regKey.GetValue("");
			'OLEDBProvider' = $regKey.OpenSubKey("OLE DB Provider").GetValue("");
		};
	}
};
