    Interesting... But isn't access still being controlled/enforced by NTFS ACLs?

      I have a 2TB SSD that was used to run Windows (on another machine), and Hyper-V...the machine it was hooked up to died months ago, but I did continue to use the SSD in an external USB dock to run the VMs. I have no use for the Windows installation on the drive; I'm not booting from it. So I tried to get rid of everything but the VMs. My god, is it ever an adventure to try to get rid of the existing Program Files, Program Files (x86), ProgramData and Windows folders - even though Windows is NOT running from that disk. Taking ownership of folders, making sure the new ACL applies to child items (files *and* folders), deleting what you can, repeating for whatever Explorer refused to delete the first time around, etc. At this stage, it would've been faster to move the 1.7+ TB worth of VMs on it to another drive, reformat it, and copy the files back. If I was trying to delete folders owned by the OS that is currently running - obviously that's bound to fail. But the OS is on a *data* drive; it *ought* to be easy to take ownership of folders, and delete the whole thing. But nope. I've also been tempted to convert from NTFS to FAT32 (that *will* get rid of all folder permissions), and then back...but that would probably be even slower than moving the data I care about, reformatting, and recopying the files... Anyone's been down that road?

      Same experience here. I had a laptop with a 2 TB hard disk having four partitions C, D, E, F, 500 GB each with C: having the Win OS. Now, that laptop fell and broke, but luckily nothing happened to the hard disk. I put a cover to this 2 TB hard disk with a USB outlet; essentially making it an external hard drive. It doesn't allow me to delete the Windows folder on that external drive. Same story with Program Files, Program Data.

          Get in trouble shooting windows when booting and remove the folders in CMD Or boot up from a external medium (Hiren's Boot, Bart PE...) and remove the folders from the virtual OS

            That's the way I'd do it - and probably a repartition to dump any bootable stuff as well.

              Yeah, the partition is NTFS, as I understand it, someone reverse-engineered it all and implemented a Linux driver so NTFS partitions can be mounted/read like any other. NTFS implements ACLs (access control lists) to determine who has access to files/folders. That's part of the file system, so the Linux driver has to follow that in order to be able to access anything. I could be wrong, but that would infer ACLs could be completely bypassed simply by ignoring them. Kinda like movies where someone is prompted for a password, and just types in 'override'. :-) I'll certainly give it a shot, I have other (unrelated) fires to put out this morning...

                  It took quite a bit of time and patience, but taking ownership of files/folders, I managed to get rid of everything (Program Files, ProgramData) except for a number of Windows subfolders. Some of them just will NOT let me take over. I'll probably just move the VMs folder to another disk and reformat the disk altogether. And merge the boot partition with it, while I'm at it.

                        Yup, I knew about both takeown and icacls (and its predecessor cacls), but there are some (deeply embedded) folders that still don't like to be reassigned. That response on superuser.com might be using a combination of command-line args that I haven't tried - thanks for that.

                          Maybe SSD's are "small" so you don't keep anything except the OS on them. I'm in awe when a product lets me install on the drive I choose.

                            Wut? This SSD is 2TB. It hosted both an OS (Windows 10) and Hyper-V VMs. Since each VM hosts its own OS, it makes sense to put VMs on SSD and not bulk storage disks like spinning disks.

                                  I have a 2TB SSD that was used to run Windows (on another machine), and Hyper-V...the machine it was hooked up to died months ago, but I did continue to use the SSD in an external USB dock to run the VMs. I have no use for the Windows installation on the drive; I'm not booting from it. So I tried to get rid of everything but the VMs. My god, is it ever an adventure to try to get rid of the existing Program Files, Program Files (x86), ProgramData and Windows folders - even though Windows is NOT running from that disk. Taking ownership of folders, making sure the new ACL applies to child items (files *and* folders), deleting what you can, repeating for whatever Explorer refused to delete the first time around, etc. At this stage, it would've been faster to move the 1.7+ TB worth of VMs on it to another drive, reformat it, and copy the files back. If I was trying to delete folders owned by the OS that is currently running - obviously that's bound to fail. But the OS is on a *data* drive; it *ought* to be easy to take ownership of folders, and delete the whole thing. But nope. I've also been tempted to convert from NTFS to FAT32 (that *will* get rid of all folder permissions), and then back...but that would probably be even slower than moving the data I care about, reformatting, and recopying the files... Anyone's been down that road?

                                    I too got tired of this problem and wrote a little cmd line tool for this.. GitHub - windojitsu/OwnAndResetAcl: Reclaim ownership and control of a directory tree.[^] OwnAndResetAcl A sanity-saving tool for dealing with those pesky "Windows.old" directories Reclaim ownership and control of a directory tree. Recursively takes ownership and resets the ACLs of files, directories and symbolic links. Does NOT follow reparse-points (symlinks or junctions).

                                    Y'know...I had actually given some thought to writing a utility or script to do exactly this, but I figured it ought to get more complex than I might have anticipated from the get-go. Thank you *very* much for the link, I'll be sure to check it out as soon as time permits.

                                      yeah there's a lot of advice out there "just run takeown.exe and icacls.exe" but at some point, Windows.old directory structures started containing pathnames > 260 chars, and directory symlinks that loop back on themselves.. it's maddening! further maddening, the .NET interop to call Advapi32 to enable necessary admin permissions, was extremely non-intuitive.. lots of old, bad code out there that works on x86 but not on x64 due to differences in struct-packing (member alignment) lmk if it helps or fails in any way.. haven't tested it on Win11, yet

                                        Quick follow-up: I just had a quick look at the source - this is excellent stuff, my hat's off to you for putting this together. You can bet I'll be using it to clear off whatever remains on my drive. They say necessity is the mother of invention, so I think I know exactly what you went through to convince yourself to take the time to create this project. It's short(-ish), to-the-point, and despite the technical complexities involved, is very well structured and elegant code. How do I vote a 5 on GitHub? :-)
