So with ReFS, maybe Windows will be able to delete or even just rename a file in use in 10-20 years time? Who knows, software updates might not take 30 minutes anymore.

Unless Windows first becomes what "DOS" or COBOL is today. Even _gaming_ is under serious threat now, who would have thought?

That was possible for a while now in Windows, when `FILE_DISPOSITION_POSIX_SEMANTICS` is specified to delete a file. I think it is even the default in newer version of Windows.

Indeed, it looks like this was changed with very little fanfare:

How is that even related? Android and macOS do that, too — and they are not using NTFS.

They all are just using process that is less error-prone (and is actually even recommended by many Linux distributions, just not enforced) instead of giving the user rope and hoping that s/he not hung himself or herself.

It's related because when you cannot delete files in use then you need to stop, delete and restart processes using the files. And when you are not 100% sure, then you need to restart pretty much everything.

It may not be the only upgrade limitation but it's an important one.

Or you nick an idea or two from the 80s ... and rename the old file in place so you can replace it.

You still need to reboot to ensure everything is running the upgrade, and then clean up all the old files, but that's not too hard ...
