I somewhere read that it's necessary a modification on the registry, but don't know what to modify.

in the mega folder you will find a file named "DLLredirectionenabler.reg"

merge it and then restart the system

I finally found it. I'm trying to get the chromium working and Waterfox working. Chrome gave me an error in the execution, and Waterfox.exe tells that it's not a Win32 valid application. I know that you can easily edit it, but I need an alternative to the CFF explorer.

I don't know if the extended kernel has any impact on java jdk 16 but it installs and works! (i doubt that oracle still cares about vista but java 8 still receives updates that work on vanilla vista)

I don't know if you can actually use it to develop things (jdk = java development kit) but minecraft 1.17 won't run without it (thank god that multimc exists because the native launcher won't load:worship:)

Without JDK?.. Why would the game require JDK while most applications rely on Runtime Environment (JRE)?

yea, i was surprised too

i don't know why it requires JDK but that's what i have installed

I am sorry to interrupt this discussion, but what you guys can say about stability of Vista with Extended Kernel?
Thinking of installing it, but is it stable enough for day-to-day use, or i should stick to vanilla Vista?

Never try installing Extended Kernel on systems that were installed using localized media (e.g. using Russian version of Vista). So you should install en-US version first, go through Extended Kernel installation procedure and install Russian MUI in the end.

JDK 16 bundles JRE 16; Java compiled apps will just use the JRE, as pointed out by @SigmaTel71  :P ...
AFAIK, Oracle no longer supply standalone JRE installers past JRE 8 (8u291 is the latest official release);
as you might already know, 32-bit support was also dropped past 8 :realmad: ...

should try AdoptOpenJDK. It has a little better performance and still allows to install JRE separately.

Thanks for that :thumbup ; also nice to see that 32-bit support hasn't been abandoned by them :) ! However, 

https://adoptopenjdk.net/releases.html?variant=openjdk16&jvmVariant=hotspot

suggests only Windows2012r2 or later is supported :dubbio:(?) ...

It does, as the Eclipse 2020-12 IDE does call win7 functions through its JRE. I believe it's using JRE 14 or 15. Worked perfect.

that it works on Windows 7 and its server equivalent as well.

Well, I tried to run 
OpenJDK16U-jre_x86-32_windows_hotspot_16.0.1_9.msi
on my Vista SP2 x86 laptop, this is what I was met with:

Probably something that can be mitigated via Orca. but not gonna try it now... Also, 

https://adoptopenjdk.net/installation.html?variant=openjdk16&jvmVariant=hotspot#x86-32_win-jre

suggests:

Note: Windows installer packages are supported only on Windows x64 systems.

i.e. the MSI installer will install the 32-bit variant of JRE 16 only on a Win7+ 64-bit host :realmad: ;
so, even when using Orca, I probably won't be able to install on my Vista x86 OS  ... 

In any case, if @winvispixp is to try AdoptOpenJDK on his Vista SP2 64-bit machine, some tinkering of the installer might be needed... ;)

I can confirm... :( I downloaded 
OpenJDK16U-jre_x86-32_windows_hotspot_16.0.1_9.zip
extracted it and probed .exe and .dll files inside the bin dir with DependencyWalker (DW); 
many DLLs look for K32* functions inside kernel32.dll (where they normally are in Win7+), 
but in Vista SP2 these function reside, IINM, inside psapi.dll ... :o
