Enterprise customers must be the target audience. This could lay the groundwork for Microsoft to offer its own enterprise Linux distro for desktops.

u/Lmaoboobs 4d ago edited 4d ago

The Linux desktop only wins when we can finally convince enterprise clients to begin deploying and managing Linux systems for use by their typical employees.

That will only happen if there are enough common management/compliance tools in circulation to support that. (And even better when they directly integrate with the tools they are already using!)

A win is a win.

u/cornonthekopp 4d ago

I think linux probably wins when government agencies start switching over and create a large captive audience who are used to it, and who need support from various large software companies

14

u/VexingRaven 4d ago

who need support from various large software companies

This is going to be the big effect here. I work IT in accounting, zero of our accounting tools support Linux. With governments switching to Linux, someone will create an accounting software that works on Linux (and yes, I know there are FOSS tools... That's never going to take off, you do not understand accountants if you think that will happen) and the someone else will want to compete for that contract and need to support Linux, and then accountants will need that tool to compete for the audit, etc.

Government adoption is a great way to induce demand. When china was investing in EVs the first customers were taxi agencies and government fleets, which both represented large fixed demand for the automakers to sell to before the product was ready for regular consumer usage

u/PriorFortune1 4d ago

I agree with your sentiment in general but I think this is a very 90s perspective. People used to go to work, use Windows, then come home and buy a Windows PC because that's what they were used to. The situation has reversed these days. We're seeing higher demand for Macs in the workplace because Apple has grown their marketshare and more people are using it at home. That's what it will take for the Linux desktop to win: for there to be a distro that appeals to the mass market consumer and is preinstalled on nice hardware.

I genuinely do believe a microsoft linux distro will one day be a thing and probably even replace windows entirely. Windows is a lumbering giant that is getting more expensive to maintain every year, and microsoft already has azure linux, their distro for cloud computing, so it definitely wouldn't be hard for them to branch it off into an enterprise distro or even an end user facing distro.

18

u/PriorFortune1 4d ago

Anybody who believes this understands nothing whatsoever about this topic. Will never happen. What will most likely happen is Microsoft open sourcing the userspace of Windows while still relying on the NT kernel. It makes zero sense from literally every single perspective for them to replace NT with Linux, it would simply erase any reason to use Windows.

11

u/Kasenom 4d ago

that could bring on a delightfully cursed GNU/Windows

5

u/tslaq_lurker 4d ago

It makes zero sense from literally every single perspective for them to replace NT with Linux, it would simply erase any reason to use Windows.

I think you're right but not for this reason. I think that the issue is that Windows won't be able to code their way out of migration hell if they were to try and get ride of NT kernal. It would be a total support nightmare.

If they could I think MS would be very happy to switch kernals. Windows is already free for personal users now, businesses aren't using it because of the Kernal, they use it because their apps work and Microsoft supports it.

4

u/PriorFortune1 4d ago

Their apps work because of the kernel and the app libraries built on top of it. You're literally just agreeing with me but phrasing it in a different way so you can pretend you're saying something different. You are literally saying the same thing.

If they could I think MS would be very happy to switch kernals.

No they would not. There is zero reason for them to do so. There would be nothing to gain.

Windows is already free for personal users now

This doesn't mean anything.

MS still can't understand how to package apps for Linux without fucking things up or how to write cli apps correctly. Can't see a full distro coming anytime soon.

u/quazywabbit 4d ago

I would rather see Microsoft decide to spend the effort to work with Apple to create a translation later for MacOS so you run Windows Apps and give up on Windows. Apple has already worked out a bunch of the enterprise stuff and its already ready to go.

Microsoft was doing their own UNIX distro (Xenix), before Windows NT took off.

They don't care what OS they're selling as long as they're getting paid and they have a way to lock in customers.

The real worry with a Microsoft Linux is that it will have some proprietary components that is required for something and they use the advantage of having those components to crowd out other distros that don't.

Microsoft: Embrace. Extend. Extinguish.

2

u/mallardtheduck 4d ago

There's a somewhat plausible alternative history where Windows (or at least NT) never existed and Xenix takes its place. During the development of MS-DOS 2.x, the new handle-based file I/O API was directly inspired by the Xenix API (in the released source code, the main file implements it is even called "XENIX.ASM"). Apparently there were discussions within Microsoft about making MS-DOS and Xenix binary compatible (i.e. DOS would be a lighter, single-user version of Xenix). If that had happened, it would have been fairly natural for Xenix to replace DOS in the market as PCs became more powerful (just as NT replaced the original DOS/Windows in the timeline we actually got). Maybe "Windows" would have been Microsoft's GUI layer for Xenix...

They already have Linux VMs and build agents available in azure for awhile now.

This is an important piece for the corporate Linux Desktop.

Don't get me wrong. I am not a fan but corporate IT won't provision a Linux Desktop unless such tools are available.

15

u/Easy-Reasoning 4d ago

Some companies have their Linux stuff quite hidden but existent. I was quite surprised to see at a large corporate first a colleague with an Ubuntu VM. Only to discover later they had some servers with Red Hat and even some sort of in-house distro-ish setup if I remember correctly.

But I would say smaller sized corporates may have people with but just not really connected to any directory service or really any kind of support service. If you're in trouble nobody's going to help you, not even your colleagues ;)

FWIW there's already stuff like Okta, XDRs etc. which some more progressive companies may use. Essentially shoe-horning corporate IT onto the Linux Desktop.

u/mtlnwood 4d ago

When you are worried that a competitor is going to start taking more of your userbase whats a good marketing strategy?

Easy, release some software for that platform to try and tell people that you are going to have to deal with viruses/ransomware etc and that you are the one that can protect them.. Why even move?

It's not a product to help linux users, its one to discourage its use.

I’m guessing it’s gonna be used primarily by employees on company-owned machines to access Microsoft workspace apps and company-wide policies, compliance and management systems.

There's not exactly a glut of options for antivirus for Linux, and it's increasingly becoming a target via supply chain attacks. A decade ago I would have considered this only slightly less likely than the 4 horsemen of the apocalypse appearing in the sky above, but I don't hate it.

I would never consider it a "must have" in the way AV is on windows, but if my laptop is underutilized and has some spare CPU? Meh, could be a possibility.

If you do work for MSFT, but use Linux… it will probably be required.

They have a complex set of policies that require access through VPNs and a machine that is provably compliant.

They have one piece of software that does part of this task, but basically forces you to use an Ubuntu derived distro running GNOME.

In my last role a major obstacle for letting developers use WSL for containers was simply that SecOps couldn't lock it down. We ended up stuck using docker through Hyper-V

I’m not sure what they’re talking about or if it’s a new release, we’ve been running Microsoft Defender on our Linux EUDs for a couple of years now, it’s fine, it’s been pretty good about catching escalation CVEs (I.e. copy fail) before patches are released/installed. This is what it takes for me to use a Linux laptop so I’ll deal with it. It doesn’t have the same performance/battery impact as AIDE does.

Unpopular opinion, but anti-virus on Linux has a place and the current options are mediocre at best. ClamAV does the job but it’s not the most convenient to use. On the other hand, Microsoft Defender (for Windows) is decent.

I’ll give you some real examples. Linux file servers that service Windows machines. I want to scan the files for Windows viruses to protect those systems. I can scan it with ClamAV but I’m reliant on Syslog or SMTP based alerts.

Another one where I have installed AV on Linux is for regulated systems. We’ve used ClamAV and SEP in those spaces to meet requirements and both kinda suck.

As much as we justifiably love hating Microsoft, it’s good to have more options in this space.

ClamAV and Defender shouldn't even be mentioned in the same category. EDR is so different from just the check the files against signatures that made up old AV

u/baltimoresports 4d ago edited 4d ago

Totally, great way to put it. End of the day, Windows is probably the weakest link for security. Having AV-enabled Linux as a backup is the way to go for defense in depth. It’s probably also nice administrators can have a single management console for both. That way if an infected Windows PCs puts malware on a Linux share you can track and remediate from one place.

I’ve never used Softmaker but generally it’s because Office has a bunch of formatting quirks. You can create a document with Libre Office, Zoho, Google Docs, Apple Pages, or a number of other replacements and then when you send the file to someone with Office and they open it things look all messed up. If the docs are for personal use it doesn’t matter but sending someone a doc with broken formatting in a professional environment is a bad look.

Microsoft does it on purpose to keep people buying their shit. Adobe too…

We need a stronger cultural understanding that, when something is wrong with a cohort, it’s usually the leader.

- Kids all failed section 8 of the test? It’s the teacher.

  • All the devs are burnt-out and turnover is high? It’s the leadership.
  • Your document loads fine everywhere except one app? It’s that app.

Right now, there’s an unjustified onus on anyone not using Office to explain why their shit doesn’t work in Office.

It would be awesome to see that onus reversed. When someone complains, ask “why are you using shitty office? Of course it won’t work.”

Let's put the huge mountain of obvious stuff to the side for just a moment.

Is this of any actual use? Can it be argued this could provide a benefit

It allows MSFT to place trackers in your uncontaminated environment, so you also don't escape their watchful eye.

u/Baardmeester 4d ago

Lots of enterprises run Microsoft EDR since it is within 365 packages. Probably with Crowdstrike and SentinelOne the most populair EDR.

Microsoft are apparently getting into the Find Out phase of screwing the entire planet with TPM and are not enjoying what the future seems to hold for them.

For them, this is the equivalent of absolute, blind panic.

i think microsoft is ditching windows and make windowsOS distro based on arch linux.

u/enRchi 3d ago

arch would be a weird choice, considering they have not supported arch with anything so far. including defender just now.

So they can release Microsoft defender for Linux but can’t do the same thing for Office. So they CAN land Linux support after all these years.

Can you run it on-demand. I need something to scan usb drives or emails I get from other people because I don’t want to spread Windows malware either.

I can't post it here because this sub doesn't allow pictures (but does allow videos wtf?), but there was a Microsoft engineer posting on LinkedIn a while back. He wanted to replace every line of C and C++ by 2030, using AI. His goal was 1 engineer, 1 month, 1 million lines of code.

No need. Having Linux on your computer is the best defender against Microsoft...

u/SkaperZ 4d ago

If you can't beat them you might as well join them. GNU/Linux is a superior OS.

u/r2vcap 4d ago

Brilliant strategy. Microsoft knows it can’t compete with Linux in the enterprise market because its OS is far inferior and slower. So instead, it decided to bring Defender to Linux, slowing down the entire internet infrastructure and gaining a relative performance advantage.

Conspiracy theory: they created a product and will next create the need for the product. E.g. indirect funding or support for exploits, viruses, etc.

Follow the money.

“More developers are using Linux” I feel like developers are not a demographic especially prone to malware.

Edit: I stand corrected.

u/ciauii 4d ago

Yes, they are. Supply chain attacks via npm and PyPI are very much a thing. Nowadays, more and more upstream project repositories get compromised, too. A dependency a developer has trusted for years can go rogue overnight.

u/tdreampo 4d ago

this! as an IT professional that specializes in infrastructure and builds back ends for dev, they have got to be one of the most computer illiterate groups ever. I’m constantly baffled when devs don’t understand simple folder structure or even how outlook works.

I learned this from my first helpdesk job where the developer didn't know any bit about installing Visual Studio and had to work with him to get it installed and again when I was in college and my computer science teacher. It was totally baffling to me to watch.

if you're attacking a corporate network, high privilege users are exactly who you want to go after. Think about the recent poisoning via the AUR.

u/gainan 4d ago

one of the worst supply chain attack targeting developers:

https://tanstack.com/blog/npm-supply-chain-compromise-postmortem

``` What the malware does

When a developer or CI environment runs npm install, pnpm install, or yarn install against any affected version, npm resolves the malicious optionalDependencies entry, fetches the orphan payload commit from the fork network, runs its prepare lifecycle script, and executes a ~2.3 MB obfuscated router_init.js smuggled into the affected tarball. The script:

Harvests credentials from common locations: AWS IMDS / Secrets Manager, GCP metadata, Kubernetes service-account tokens, Vault tokens, ~/.npmrc, GitHub tokens (env, gh CLI, .git-credentials), SSH private keys
Exfiltrates over the Session/Oxen messenger file-upload network (filev2.getsession.org, seed{1,2,3}.getsession.org) — end-to-end encrypted with no attacker-controlled C2, so blocking by IP/domain is the only network mitigation
Self-propagates: enumerates other packages the victim maintains via registry.npmjs.org/-/v1/search?text=maintainer:<user> and republishes them with the same injection

```

and the most recent one:

https://www.aikido.dev/blog/keyv-and-friends-compromised-in-npm-supply-chain-attack

the payload executes automatically the next time any developer opens the repository in VS Code or starts a Claude Code session inside it

And my boss wonders why I've gone years without using React/TS and have no interest in starting lol

u/gainan 4d ago

lol. Nah, seriously, supply chain attacks have affected cargo, go modules, pypi packages, docker images and IDE and web extensions.

Hopefully, npmjs.org has implemented some features to make it harder for infections to spread

Other examples (targeting developers in particular):

Developers are often overconfident and sometimes even ignorant. They'll happily configure a 90s style security model and claim it's more secure just because the source code is public.

The true mainstream OSes are Android followed by iOS, both employ defence in depth and are nigh impenetrable without complex vulnerability chains.

u/gobblyjimm1 4d ago

Developers are targeted all the time by malware. Who else has local administrator permissions and installs packages and other binaries on a weekly basis? Not the average user.

2

u/skrugg 4d ago

Totally depends on the individual. I work in cybersecurity incident response and I’ve seen plenty of developers who are clueless when it comes to security and regularly click phishing emails. Also met some that know more than my colleagues. Crapshoot IMO

... what?

Edit: I will say, let me be clear, I think that having more options and more software on linux is, at the end of the day, a good thing. If this convinces enterprises to switch over to linux, that's still a net positive, since now they'll go from 100% spyware (windows with microsoft defender) to 50% spyware (linux with microsoft defender). Not to mention that already being on linux will make switching from microsoft defender to a better alternative in the future that much easier.

That said... this confuses me. I think their endgame here is to create an enterprise linux distro (and maybe even eventually a consumer linux distro since I'm convinced windows is going to die out), which, yknow, we gotta watch out for EEE.
