I am using WSUS for windows offline patch management , I am using xml’s provided in WSUS for checking patch applicability on any machine , But I am not able to find proper patchs through that , I am getting many patch which are not applicable in the machine as missing ,
How can I get the proper patch using WSUS secer and xml provided by it

I am scanning all the xml’s found from WSUS , I determine the missing patches and the discard the superseded patches , but then also I find many not applicable patches.
