- There is no Windows XP Pro 64-bit Service Pack 3.
- There is no 32-bit version of Windows Server 2008 R2.
- The Convenience Rollup update for Windows 7 and Windows Server 2008 R2 requires the April 2015 servicing stack update.
- Windows 10 feature upgrades are cumulative as well. You only need to install the latest to install all available feature upgrades.

Hello,
Some typos happened:
Windows 10 version Name Release date
Windows 10 build 1507 initial release 29.07.2015
Windows 10 build 1511 November Update 12.11. 2 0 1 6
Windows 10 build 1 6 1 1 Anniversary Update 2.08.2016
Thank you for the post!
Wasn’t Windows 10 supposed to be the final destination (har har) for Windows? Ah well, it wouldn’t surprise me if in 2020 or so M$ will warn Windows 10 users that thay’re running an archaic and insecure OS and how much better Window 11 is.
+ IF their claims are correct, LTSB 1607 should have support at least until July 2026..
Isn’t the anniversary update build 1607?
You are right, thanks!
Non-Windows user but this is a very useful and informative post! Bookmarked for future reference. The only question I had while reading this was answered: “you only need to install the latest available Service Pack and not previously released ones. Exception:…”
Eight people in the world control half the world’s money? I did read that correctly? Bill Gates is one of the eight.
Just a thought that is mind-boggling–like Czarist Russia and Marx, Lenin and Engles and the reason for the Revolution.
Here’s the thing, which -totally- messes me up – whenever I look at manually running WU, lolz – BECAUSE Micro$oft has ensured that their Windows 7, Service Pack 1, OS (Retail and/or OEM) will no longer update itself – no matter WHAT we do; unless these procedures are followed, right. Aanyway, this page…
Some notes (which do not cover THIS):

(https://www.ghacks.net/2010/12/20/microsoft-windows-update-overview-all-you-need-to-know/)
… This page takes us to the download @https://www.catalog.update.microsoft.com/search.aspx?q=kb3125574 (Around 500 MB)
HOWEVER, January 2017 comes along and we’ve got the SAME FILE – except, it is now -only- about 150 MB, https://www.catalog.update.microsoft.com/search.aspx?q=3212646
Soo, WTH are we supposed to do (dang it, hehe)?!?? I have: 1) installed (all) prerequisites (successfully!) for teh Internet Exploder 11 to run (and it does, all within Oracle’s VM VirtualBox, current version 5.1.14!) and 2) “downloaded the following patches from the Microsoft Update Catalog first”, as per https://www.ghacks.net/2016/11/02/checking-for-updates-slow-on-windows-7-here-is-the-fix/ and 3) now I do NOT have a CLUE whether the two Micro$oft Catalog files are cumulative, or not (makes no sense, that they would be, as they are 500 MB vs. 150 MB.
IDK., why must they make it so convoluted; when, it could’ve been all so simple (baby!) :)
