Using NetChk Protect 7.8.0 Build 1388, XML 220.127.116.110.
I had already installed MS11-A06 / Q2607712 on a Windows XP Pro SP3 system. Today, based on a scan using the XML listed above, I applied the following: MSRT-001 / Q890830 MS11-071 / Q2570947 MS11-072 / Q2553072 MS11-072 / Q2553074 MS11-072 / Q2553090 MS11-073 / Q2584052 MS11-073 / Q2584063
Now, NetChk shows nothing missing, but Windows Update says I need KB2616676, which appears to be the same as MS11-A06 / Q2607712. Searching in Patch View, QNumber containing 2616676 is not found. It looks like Microsoft may have updated or re-listed this patch as part of Patch Tuesday.
