They would not release a big one on patch tuesday directly, they will first release as preview rollup the Convenience Rollup anniversary is next week
There is a large list of superseded updates for the current patches, much larger than usual, but the Windows 7 update itself does not match the CR KB3125574 in scope and relevance. Still waiting to see the big one... like everyone else here
I'm just speculating that the CR KB3125574 anniversary seems a convenient time to start adding old fixes to monthly rollup
@abbodi1406 I'm testing an offline-updated (Convenience RU option) W7 Ultimate x64 image as per your 2017/05/02 changelog. In addition to that, online-only updates in that repository revision plus recent .NET 4.7 were installed during OS setup (setupcomplete.cmd). No other updates after those, and no network access at all. After a deepclean, I noticed that update 3210131 (.NET-related) was reported as changed from Installed to Absent. Is this one superseded/removed by .NET 4.7? And just a minor correction for 2017/05/09 changelog, I think 4015552 is superseded by 4019264, not 4014504
KB3210131 (.NET 3.5.1) is needed for non en-us systems (the same 23 langs that have LPs in .NET 4.x) corrected, thanks
