Large pages can be used on Windows without elevated privleges.

[Infini-PLEX]

Enabling large page support on windows only requires the "Lock pages in memory" user right, which can be granted on a per user basis in the Local Security Policy settings.

See the java docs (It says only Windows Server 2003, but I can confirm that it does work on modern Windows Server, not sure about desktop):

Can confirm this works on Windows 10 Pro. Just add your username to the Lock pages in memory policy. No need for admin privileges.

Before the change I'd see an error that JVM cannot use large page memory because it does not have enough privilege to lock pages in memory.

I also found this a couple weeks ago, it's in my fork.

Works on Win11 like a charm.
In case you can't find options to start policy editors I suggest also https://answers.microsoft.com/en-us/windows/forum/all/how-to-enable-the-gpeditmsc-on-windows-10-and-11/dbc76919-f2b5-4dec-a2b7-bcf545c34d00

After getting Group Policy related apps installed, I was able to nicely add option to lock pages in memory.

It also made my MC server and game to run way better.

[UPDATE]
On another Win11 machine above steps didn't work, I had to use different scripts. It worked well using guide on https://winsides.com/enable-group-policy-editor-on-windows-11-home-edition/
