WMI-Filter for client only selection, i got something wrong?

Question

I'm struggling with a WMI-Filter, so I ask you. Is the WMI-Filter right if I only want to select the XP, Vista and Win 7 Client? confused

SELECT * FROM Win32_OperatingSystem WHERE (Version LIKE "6.%" AND ProductType = "1") OR Version LIKE "5.1.%" OR Version LIKE "5.0.%"

hope you can help me out
