How does metro work? Does it work in the same way as when you press alt+ctrl+delete in Windows to bring up the security screen thing? In other words, how does it operate in technical terms?

How does it work in Windows, does it work like the security screen when you press alt ctrl delete? I think my question was very clear and understandable

So, it operates in the same technical manner as the security screen or the lock screen (Win key + L). For an example, when you press win key + lock, the screen appears immediately just like metro, it is always there?

I think he's asking how Metro was written as a whole other interface on top of Windows, and how the Shell instantiates it on startup. I think his analogy is to the Secure Desktop for login, which is a separate user interface handled by a separate (non-Explorer) process that takes over the display when you press Ctrl+Alt+Delete.

Oh, I remember that, that was on Windows 2000 and/or Windows NT.

When I was first introduced to windows 8, I wondered how Metro would not eat more memory. So metro is apart of the Windows system. So, does Metro work in the same way as when you hit al ctrl delete in vista and beyond?

The desktop is there but Metro is like Start Menu... And Metro apps allow you to view app in full screen... but you can not change to windowed version unless you have the desktop apps which can be viewed on your desktop.

I think (don't quote me on this) when Win8 was being announced they made it very clear that Metro wasn't a layer on top of Windows - it is Windows now, basically like replacing the "classic shell," but still keeping the Desktop there, but the desktop code is only loaded when the Desktop app is launched. Again, not completely sure, but I think it's more analogous to like the Windows Desktop and the command prompt or DOSBox, where the "stock Windows" is the Start Screen and the desktop is more there for older applications and applications that take advantage of the specific desktop-based Windows features. not a perfect analogy, but that's the best I could come up with :\

While I'm not sure how Metro apps are represented in the system, I can say for certain that Windows is not instantiating a 'new desktop' like the Ctrl+Alt+Del Secure Desktop. You'll notice it doesn't flicker when going in and out of the Start Menu like it does if a UAC prompt (on the Secure Desktop) comes up.

If I were to guess, everything is still tied to explorer.exe and the Desktop Window Manager. You'll notice that if you kill that process, all Charms Bars, start screen, taskbars disappear. So I'm guessing they just rewrote explorer.exe to show the Start 'menu' first and the desktop later, Metro apps are Windows apps that use WinRT (as opposed to Win32) that draws to fullscreen Direct2D surfaces represented inside the Desktop Window Manager, like every other window.

I see now, Metro and the desktop work almost the same way. Metro is like alternate desktop then. I still like and always will like the start menu though. Metro may be nice and everything, but it makes people a lot less productive. Microsoft really did not need to get rid of the start menu, it worked fantastically. Metro is designed primarily for the tablets!

When was this thread ever a technical discussion, the OP question didn't even make any sense, it took most of the first page to work out what he was saying

It did make sense. You cannot expect someone that is trying to ask a technical question and hence obtain more knowledge to form it coherently if he is trying to learn more about this topic.

Metro is part of explorer.exe so it is not like hitting control alt delete. Try killing the explorer.exe process and see for yourself.

Metro Apps on the other hand run separately.

    • Anthropic pulls Fable 5 and Mythos 5 after US export control order

      By pradeepviswav · Posted

      Anthropic pulls Fable 5 and Mythos 5 after US export control order by Pradeep Viswanathan In April this year, Anthropic launched the Claude Mythos Preview frontier model with state-of-the-art cyber and coding capabilities for a select set of companies around the world. After preparing appropriate guardrails, early this week, Anthropic launched Claude Fable 5 and Mythos 5, its most capable AI models. Claude Fable 5 is for general users and comes with strict safeguards, while Mythos 5 is designed with fewer safeguards for cybersecurity and biology use cases. Today, Anthropic abruptly suspended access to its Fable 5 and Mythos 5 AI models for all customers after receiving an export control directive from the US government. The company received the directive from the government today at 5:21 p.m. ET, and the received letter did not provide any details regarding the national security concern. Anthropic understands that the government became aware of a method to bypass, or “jailbreak,” Fable 5, which might be the reason behind the directive. The order was issued under national security authorities and requires the company to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether they are inside or outside the United States. The restriction also applies to foreign national employees working at Anthropic. As a result, the company has disabled both models for all customers to ensure compliance. Access to previous Anthropic models like Opus and Sonnet is not affected by this government order. The company highlighted that it had developed strong safeguards to reduce the possibility that Fable is misused for tasks related to cybersecurity. In fact, many developers are complaining that the safeguards are going overboard. Additionally, the company worked with the US government, the UK AISI, multiple private third-party organizations, and internal teams to red-team Fable’s safeguards for thousands of hours. Finally, Anthropic noted that no testers have yet been able to find a universal jailbreak on Fable 5. As expected, Anthropic disagrees that a narrow potential jailbreak should lead to the recall of a commercial model used by hundreds of millions of people. It warned that applying this standard across the AI industry could effectively halt new frontier model deployments. Anthropic concluded by mentioning that it is working to restore access to Fable 5 and Mythos 5 as soon as possible and plans to share more details within the next 24 hours.
