.Win8.1 kb5017220 ESU Licensing Preparation Packages issued via catalog

was expecting something for 2012 R2 sooner or later but Win8.1, wonder if 0Patch will do a u-turn on supporting Win8.1 beyond Jan 2023…
But the Catalog lists downloads for Win7 x86 and x64
not necessarily, Win server 2012 R2 shares the same code-base as Win8.1
that’s probably why MS have skipped a new document for Win8.1 using win 2012 R2 as a reference – much the same

note that there are both 32bit & 64bit versions of the KB5017220 update available
so it covers both Win8.1 & Server 2012 R2 (but Server 2012 R2 is 64bit only)
But the Catalog lists downloads for Win7 x86 and x64
that’s a different KB update for Win7, PKCano
the equivalent ESU LPP update for Win7 & Server 2008 R2 is KB5016892
not necessarily, Win server 2012 R2 shares the same code-base as Win8.1
that’s probably why MS have skipped a new document for Win8.1 using win 2012 R2 as a reference – much the same
not exactly. only Server 2012 R2 has the same codebase as Win8.1 (NT 6.3)
Server 2012 RTM or original, on the other hand, has same code base of Win8.0 (NT 6.2)
missed out the R2 OOOOOOPS
now fixed
And Server 2012 R2?
Server 2012 R2 will have at least 3 years of ESU Updates https://learn.microsoft.com/en-us/lifecycle/products/windows-server-2012-r2
It’s possible to use the ESU Bypass to install those updates on 8.1 as well.
