Hey,
Since this is fastly written: In case the Insiders dont know how to install Windows 11 in a ReFS partition, here a short Guide.
The advantages for this Filesystem instead of NTFS you look yourself, i just say, i dont see any disadvantage.
Iam not sure if Windows 10 does also support it, but you can look yourself in Drive Managment if you can select reFS as Filesystem.

And here the fastest and easiest way, lol i think i dont need to write anything, the Screenshot is enough, anyway.
On the Windows Setup Partitionscreen, create the Partition(s) as you do usual.
Then open Command Line, so Shift+F10
and now i dont know anymore whats next, sorry, thats all for now. I hope this Tut is helpful.

No wait, i remembered just right now! Hell, iam intelligent, now i understand why i have an IQ of 120 and why that killed my life
So OPEN "diskpart" in Command line
write "list disk" to LIST all HDDs you do have.
SELECT the disk where you did just partitioned in Windows Setup GUI with "sel disk 0" for example. Well, i think disk 0 is anyway default most peoples.
Then SELECT the Windows Partition like "sel part 3" in my case
Then FORMAT the partition with ReFS via "format fs=refs quick"
And just for confirmation it worked write "list vol" now. You should see ReFS as Filesystem.
And Thats all. Close CMD, refresh the Partition Screen, everything should look the same. And Continue the Installation.

The newest Windows Server Insider is able to format as i know directly from the GUI.

You can use an unattended file to format your Windows volume as ReFS.

There's a few drawbacks: ReFS doesn't support EFS (Encrypted Filesystem) and therefore no paid Store apps; and no extended file attributes (alternate data streams for file metadata).

Code:

Yes sure is it with an unattented file also possible, while i myself would never do that since i have partitions where i store since i was born, so since iam 9 month old files where i think its better to format in a controlled and safe way and i cant blindly trust that the PartID is always the same, even the DiskID. There is no reason to trust it.
Yes thats right, ReFS doesnt support EFS, nor filecompress, hardlinks. About paid store Apps, maybe as a workaround creating a NTFS partition for apps which are DRM protected.
Buw now i understand why ChatGPT didnt worked to install while all other Apps did. I will sure find myself a solution, just now i think about Sandbox++, but i played too less on it to know what is possible with it. ext USB HDD or Stick. Well there r many things which is worth to try instead give up.
Who knows, maybe MS will have in the future a solution. Now ReFS does already gets soon official released for Server.
Its a long time ago where i installed the Server. Does MS Store exist in Server?
 
i dont need much things from store, but in cases i need something, i have also an App :)
More then 6 apps i dont need anyway, and only ChatGPT is protected, when i have time i find a solution for such apps. Easy going
