We are pleased to announce the release of ReactOS 0.4.15! This release offers Plug and Play fixes, audio fixes, memory management fixes, registry healing, improvements to accessories and system tools including Notepad, Paint, RAPPS, the Input Method Editor, and shell improvements.
We chose to release this version of ReactOS in honor of Eric Kohl's first commit to the ReactOS code base, which dates back to 1999.
[...]
0.4.15 was branched 6 months ago. Since then, many new and exciting features have been worked on in the master branch. UEFI support, symmetric multiprocessing (SMP), a new graphical installer, a new NTFS filesystem driver, power management, and newer application support are just a few features being worked on. We are excited to share this journey with you as ReactOS improves and matures.

I'm Pierre Schweitzer, one of the ReactOS developers. This is a free operating system that aims to re-implement Windows, but this time with an open source license.
ReactOS now supports reading files from NTFS volume. This was a long awaited feature people were asking for. And here it is.
You can see what I'm talking about on the three pictures [included in the fine article].
Microsoft's telemetry features in Windows 10 are a privacy advocate's nightmare. Now that Microsoft is trying to back port these "features" into existing versions of Windows, it seems like many of us have no future upgrade path. Sure there is Linux, but I have some older Windows software that I still want to use. ReactOS is still out there, but does not look like there have been any updates in a while.
Does the Soylent community believe it is possible to get this project going full steam to producing a useable alternative for existing Windows users?
For those not following this project it is a FOSS reimplementation of the Win32 interface, which supports a great deal of humanity's historical computational effort. The new ReactOS release has reached 0.42 and the filesystems ext, btrfs are apparently RW, though Reiserfs and UFS are readonly mounts, successful systems have been shown running.
A nice gallery of some successfully run high profile applications is here (e.g. SimCity and PhotoshopCS2 !!), although interesting, not why I am reporting this.
There are an *enormous* number of scientific instruments (not just microscopes, but various scanners, PCR decks , robots) which originally came with a Win32 driver disk, and have since gone out of business or stopped support. There might only be a single run instance on a crusty old i386 (yes, I've seen that!!).
This is an ambitious project and of course depends on the effective WINE project. It deserves some specific credit and visibility, for providing a possible threshold in the future that sufficient OLD applications can be run independent of the new Microsoft "One OS to rule them All", that it may be possible to construct hybrid machines running Linux, and sufficient driver support from ReactOS to manage the old device drivers that WINE may find difficult to reverse engineer.
But in general, more OS choice's are a good thing!
Softpedia reports
The ReactOS project recently showcased on YouTube [that it's] possible to virtualize the Mac OS X 10.4 operating system on their free and open-source Windows alternative operating system.
Our "Watch" series of articles continues today with a very interesting one where you can see Mac OS X 10.4 Tiger running inside the ReactOS computer operating system, which we believe has come a long way, and it's beginning to look like a viable alternative to Microsoft's Windows 7 or Vista operating systems, perfect for desktop computers and laptops.
The latest release, ReactOS 0.4.8, showed us last month that it's now possible to use Windows 10, Windows 8, and Windows Vista software on the free and open-source operating system that's binary compatible with computer programs and device drivers made for Windows.
It also introduced initial support for reading data from NTFS formatted drives, a new app similar to the DrWatson32 software for Windows, some user-visible changes like support for balloon notifications in the system tray area, and support for unmounting network drives directly from the file explorer.

I followed ReactOS almost since the start and always found it an interesting project, both from the point of view of seeing if they could in fact reverse engineer and create an open source version of Windows, and whether MS would tolerate this or go after them with a department of lawyers. So far it seems things have been quiet on that front, while they add more features and compatibility and get closer to a working OS.
While I doubt ReactOS will ever replace my Unix/Linux systems (just from an architecture design point of view I prefer the UNIX way) it is interesting to me if it allows me to run some old games and software. I still have windows 2000 and XP in virtual machines for such events, but if ReactOS can run the software then I'm happy to give that a go instead. Past attempts were not very successful on that front, but admittedly I last tried ReactOS 10 or more years ago, so perhaps time to try again.
I guess the wider question is whether ReactOS will ever be an alternative to proprietary Windows, especially as more and more remaining Windows users seem unhappy with the direction MS is taking the Windows OS. I guess it depends on how good ReactOS will work with new Windows software vs older stuff.

With things like WINE, do you need a whole Windows OS re-implementation? I got off the Windows treadmill in 1997. I went cold turkey. I've pottered about with WINE occasionally if someone tells me to run a Windows program to do something specific and it has often worked well enough. When things like LibreOffice came along, that reduced the need for WINE even further.
Microsoft is pushing Linux hard these days. Everything's WSL and Azure. Why would they continue to invest in Windows development long term?

Some software will not work on Wine because it needs deeper hooks into the system and/or kernel. Likewise any software that has a hardware component or its own driver will not work on Wine.
Still ReactOS and Wine work very closely and collaborate, the userland of ReactOS is basically Wine, so any improvements between the two projects are shared.
From my perspective, I have software that runs better (or at all) on Windows in a VM than Wine (e.g. some Audio software), as well as old games, some that work on Wine and some that don't. So while I do have Wine installed and used occasionally, the XP VM is used more often.
Beyond that, a previous place I worked at still uses WinXP/2000 (and even Win 98!) heavily, because the robots they purchased decades ago only work with those OSes. You can't run on Wine because the software has custom drivers and HW to connect to the robots. Keeping those ancient OSes secure and reliable requires a lot of manpower and cost, so replacing it with something that is compatible, yet is still getting bugfixes and security updates (plus perhaps with some modern features like inbuilt firewalls) would be a good use case for ReactOS (if it ever reaches that point, which they seem to be trying to).

Some things involve hardware drivers that aren't available outside of a Windows or OSX environment. From what I can tell, ReactOS can handle some regular windows drivers, albeit mostly older ones from XP/2003, which can make it a potential option for people that have older hardware that doesn't have drivers that work with newer versions of Windows.
I haven't loaded ReactOS in a while, I've pretty much always got a copy of Windows sitting around, but I think ti's probably about time that I did, just because of the horrible direction that MS is taking with 11 and the lack of any particular guarantees that copilot won't get more insistent about trying to trick people into allowing it to snoop.

FWIW I tried installing it, things I found out so far:
1. SMP initial install works fine, but when it reboots and starts to load the GUI installer the VM crashes. Reinstall with a single processor worked fine. So it looks like SMP support still needs some work.
2. It looks far more polished than the last time I used it, it actually looks usable, the theme is nice and you have multiple theme choices, including the "Classic" one which looks a bit like Win2000
3. The GUI application manager is a nice touch, allowing you to install (presumably) tested and known working versions of software (both open source and Windows-ecosystem freeware).
4. Sound works fine in VirtualBox
That is as far as I got at this point in time. I found some niggles, specifically:
1. The version of WinSCP in the application manager doesn't could not agree on a host key algorithm with my FreeBSD server (perhaps the version of WinSCP is too old?)
2. Virtualbox "shared folders" doesn't work, but I guess that is to be expected as I doubt Oracle bothered to implement it for ReactOS
As its been so many years since I ran anything Windows I actually don't have Samba set up at home, only NFS, so with the two options above not working I can't actually find a way right now to access my software archive and try some old games and software I have. I will tinker with it when I have more time in future. Although seeing the "Abyss web server" in the application manager was a nostalgia hit, that was the first web server I ever installed a quarter century ago and what started me on the road to learning web design/HTML and making my own websites.
Other things I've realised is that they still only target 32-bit Windows (Server 2003), specifically the win32 API. This means that they are not even aiming for modern Windows software support. As such as a project its main usefulness will be in replacing legacy Win200/XP/2003 systems that are still running but are otherwise without patches and updates, as well as for running software than needs more than the plain userland abstraction that Wine on *nix supports. This is probably why MS leaves them alone, they are not really in competition.

I need to look at this new one. Previous ReactOS had some holes, but was to where if I had to, I could live with it.
My hosting won't speak to WinSCP5.x anymore either, but 6.x works -- same reason, I assume.
They're working on 64bit, but I gather that's a less-than-simple transition. Agreed that's going to be necessity.
Microsoft leaves them alone because React's code is adamantly clean-room, and I vaguely recall there's already been a lawsuit proving that.
A reproducible oddity:
Install ReactOS (whatever was 2 versions back) on random aging hardware.
Now install WinXP as a dual boot. (I did this to cross-test accessories and such.)
In this setup, WinXP actually uses less RAM than ReactOS (80mb vs 85mb). Conversely a normal standalone XP install on the same hardware uses 386mb (ever wonder if that was deliberate?). I think the difference is in what drivers are not installed, but.... why?? there's no visible difference.
And there is no Alkibiades to come back and save us from ourselves.

With every layer of cruft that gets piled on top of Windows with every release, I guess ReactOS might never catch up with the current state of desktop affairs. However, there are countless vertical market applications like machine control, or some sort of stock bookkeeping. Here, the users are already fed up with the shenanigans they now have to expect from Windows on a regular basis, and if they think the hoops they have to jump through to get (legal) LTSC versions is one shenanigan too much, ReactOS seems like a cromulent alternative. More so, if they have the means to iron out minor quirks at their source level to make it work smoothly.

When I last spent some time with it, the main issue was that memory management was the suck, and rapidly clogged itself up (tho it only used 85mb at boot). But the other necessities of life did well enough (USB wasn't supposed to work, but it did anyway). I'm happy to see it progressing -- that's been accelerating.
And there is no Alkibiades to come back and save us from ourselves.

Assume Widgetizing Industries Corp have an installed base of 5000 Widgetizers (from 1990 to 2020 models) worldwide. These boot into a kiosk mode, and they care a rats ass about what is below as long as it is cheap and doesn't annoy. The only thing that keeps them from shipping ReactOS after testing is that it leaks memory like macOS Monterey. I'm sure they can wave a few grand at the ReactOS people and make that leaking go away for good and be set for a glorious future of widgetizing without Windows.
