How to remove ACL functionality altogether in Windows 10 / NTFS?

Solution 1:

I haven't seen Win 10 on exFat or Fat32 (not sure if you can do it), but I have tried both filesystems as C: drive with Windows 8 a long time ago.

I was just playing around with Win 8 at the time and tried it to see if it was possible at all. Had to do some funky things. Needed to make and format the partition first, copy the content of the Windows installation files to a folder on that partition and then run the actual setup from there to prevent Windows from re-formatting the partition as NTFS. (Can't remember the exact steps. It was 8 years ago.)

Windows 8 wasn't noticeably any faster on exFat than on NTFS. Fat32 was noticeably SLOWER however. (I presume the Fat32 filesystem drivers are really legacy and have not been much optimized over the years.)

Since there is very little difference in the exFat filesystem and ACL handling between Windows 8 and Windows 10 I am fairly certain it wouldn't be noticeable in Windows 10 either.
