Many people are wondering what the latest ESU updates for the various NT 6.1 systems are. I made a list of all the latest ESU updates, and this will be updated until 2026-01 (final Server 2008 patch)
Good thing to note is that all extended updates are compatible with Windows 7, so you could install Server 2008 SP2/R2 patches and Embedded Standard POSReady patches on Windows 7, provided you have an ESU license.
All downloads are from the official Microsoft Catalog website. Microsoft Help articles are provided along with the updates (click the name to the right of the KB number)
KB updates marked in red are final, and will not be replaced
Officially, Microsoft does not recommend you to install ESU patches meant for other systems. Unofficially, there are no problems currently, but be wary of sudden computer-breaking problems that arise.
Addendum 12/10/2024: Microsoft fixed the latest update compatibility with Windows 7. You can now continue getting updates for Windows 7 until 2026-01.
Addendum 01/16/2025: I cannot finish replacing R1 updates, though SP2 updates have been published. Installing the Servicing Stack update is highly recommended.
10/07/2024: Added Windows 7 SP1
10/08/2024: Added Windows Embedded Standard 7 and Internet Explorer patches
10/08/2024: Added Windows Server 2008 R2, and updated Windows Embedded Standard 7 (final update for that one).
10/10/2024: Added Server 2008 SP2, and did the .NET rollup for that one. I'll get around to the others.
