Prerequisites:
Java 8 (If this fails, a couple other options are Oracle Java 8, and this other OpenJDK 8.)
Notepad++ (Or anything better than stock notepad.)
oLauncher (I'm not sure if there is any other launcher that runs on XP and could work for this.)
Fabric Loader (Download universal jar.)
Fabric API
Not So New
ForceGL20 (Optional, can fix the game not launching if you have an old GPU or bad GPU driver.)

0: Open and log into oLauncher if you haven't already.
1: Go to Edit Profile and select the game version you want to play in the list.
2: Click Play to let it download the files.
3: After it downloads the files, and tries and fails to run, close the two errors and the launcher.
4: Install Fabric for your preferred version.
5: Go to the .minecraft directory (Usually %appdata%\.minecraft)

If wanting to play 1.19+, follow these below steps. For 1.18, skip until step 19.

6: Open the versions folder, make a copy of the version you want and the respective Fabric Loader for it.
7: Rename these folders to whatever. I like to do funny-(version) and funny-fabric-(loader version)-(version)
8: Do the same for the .jar and .json files inside.
9: Open the .json file for your renamed Minecraft version.
10: Rename the id string at the top to reflect the folder name as well.
11: Ctrl + F openal
12: After the first entry are entries for :natives-(OS), replace all of these with the below.
► Show Spoiler
The openal entries should look like the below now.
► Show Spoiler
13: Do the same for stb, replace the :natives-(OS) entries with this below.
► Show Spoiler
The stb entries should look like the below now.
► Show Spoiler
14: Save the file.
15: Now go to the renamed Fabric folder, and open the .json file.
16: Rename the inheritsFrom string at the top to reflect the renamed Minecraft version folder name.
17: Depending on the version of Fabric, the id might be right below inheritsFrom, or very close to the end of the file. Find the id string and change it to reflect the folder name.
18: Save the file.

19: Back out of the versions folder, and make a mods folder.
20: Move Fabric API, Not So New, and optionally ForceGL20 into it.
21: Back out of the mods folder, and make a config folder.
22: Make a fabric_loader_dependencies.json file.
23: Paste this below into the file. If you have any other mods, you may need to add them to this file with the same override.
► Show Spoiler
24: Save the file.
25: Open the launcher back up and select the renamed Fabric version.
26: Start the game.

Now you should have a Minecraft release newer than 1.16.5 running natively on stock WIndows XP.

Hi :) Thanks for your work!
I tried it on my XP 64 system with version 1.18.2 & 1.21.3. 1.18.2 works great! :)
But with the 1.21.3 I get an error message in the OLauncher:
► Show Spoiler
Fabric 0.16.9-1.21.3
FabricAPI 0.107.0+1.21.3
NotSoNew v6.15

I tried Fabric Loader version: 0.15.11-1.21.3, 0.16.7-1.21.3 & 0.16.9-1.21.3. I am using Java 1.8.0_152 x64.

Do you have any idea how I could fix this error?

I'm not sure. This is probably something I'd need to try when I get around to testing newer versions and trying my idea that could make it work on x86 as well.

I made a version of fabric with this bug fixed.
