OneXPlayer is a direct competitor to Valve’s upcoming steam deck. This device is clearly inspired by Valve’s offering and it shows all over the place, from its looks to its purpose and aims to PC gamers as a handheld device.

Hardware under the hood

This device is packing a 7-inch 1080p display, 11th generation Intel Core i7-1195G7 CPU, stunning 16GB of RAM, 512GB SSD drive with the option to purchase 1TB or 2TB model. GPU of choice is Intel iris Xe Graphics that is in our opinion a bottleneck in the whole system and for more demanding games, we believe switching them to 720p would be a better option. Everything here is powered with a 10455 mAh lithium-ion battery.

OneXPlayer inputs and other stuff

Handheld is equipped with dual bumpers and dual linear triggers. The console comes with dual speakers on both sides of it. Inside the console, there is an aluminum heat sink with copper heat pipes and a fan in order to cool internal hardware. On the outside, we have two USB-C ports and one USB-A port for connections, and of course, a headphone jack for headphones. The console comes with Wi-Fi 6 and Bluetooth 5.0 for wireless connectivity.

Price

The base entry model will cost you a whopping $1.259, 1TB model $1.399 and 2TB one will go as far as $1,599. With this kind of price, I am not sure it can come up as a winner against Valve. Sure it is packing fully licensed Windows 11 that will for sure offer more options than Stem’s OS based on Linux but even with that advantage I do not think it justifies such a big price difference.

Conclusion

Of course, this kind of console or handheld PC will still find its customer base, many users will probably like it since it comes Windows ready out of the box. Sure, you can place Windows on Steam deck as well but you will need to know how, where everything is ready and you can run beside steam other launchers without issues like origin, uplay, gog, etc. How this will be accepted by community time will tell but it is good to see that there is variety and competition in handheld PC space.

Loving Windows 11 so far? We sure are. Microsoft has clearly decided to take its OS to the next level and keeps showing it through every update. It makes you wonder what’s next - and today, you’ll find out!

Tons of new features have been leaked, and we can probably expect them with the 23H2 update. Here’s everything you need to know so far.

What’s Windows 11 23H2 bringing?

There are plenty of new features already confirmed for Windows 11. The only issue is we don’t know for sure if they’re coming with the 23H2 update or separately, at a different time. Whatever the case, a lot of them are pretty exciting.

Here’s an overview of what we might be getting this fall.

• Windows Copilot. Microsoft wants to add this AI-powered feature based on chatbots like Bing Chat and ChatGPT to assist users with all kinds of actions and tasks on the platform. As part of this development, the integration of first- and third-party plugins and the Bing Chat AI will be enhanced. This is a pretty amazing addition to look forward to, if you ask us.

• Dynamic Lighting. RGB lovers will rejoice upon this one! Dynamic Lighting will allow you to control your RGB-powered components directly through the Windows Settings, allowing smooth integration of your favorite peripherals with your OS. No need for third-party software anymore!

• Taskbar enhancements. Microsoft has announced some neat improvements to the Windows 11 taskbar. For one, we’ll be able to hide the Time and Date now, which is extremely useful for focus, but also for clean screenshots. Another change is the ability to shut down programs directly from the Taskbar, without having to run the Task Manager.

• Expanding native support for archive formats 7-zip, rar, gz and others on the libarchive open-source projects.

• Microsoft Store AI features. The theme of AI power is clearly being taken up a notch, because the Microsoft Store seems to be getting several awesome features in this regard. One of them is AI hub, which “curate the best AI experiences built by the developer community and Microsoft” (Windows Developer Blog). We’re not sure what that means exactly, but we sure can’t wait to see.

Another is AI-generated keywords, designed to improve the discoverability of apps you’re searching for. Moreover, the AI-generated review summary is designed to give us a simpler experience looking at reviews. Huge numbers of reviews will be compiled into a summary that’s easy to scan and lets us discover new content faster.

• Other Microsoft Store improvements. Business owners will be happy to hear that Microsoft Store ads will now reach 150+ regions worldwide, significantly increasing the audiences they can target. Furthermore, there will be enhancements to the Backup and Restore functionality to give users a more seamless experience in case they switch devices. 

• File Explorer changes. Rumor has it that Microsoft is working on a Gallery to be embedded within the File Explorer. The addition of a Recommended section might be on the horizon as well. 

• Widget Panel update. The introduction of the Widget Panel in itself was exciting for many. As a next step in the development of this feature, Microsoft is planning to make it possible to pin widgets to the desktop. 

• Presence sensor. You might actually already have this one, as it was rolled out as part of Moment 3 for compatible devices. With the Presence sensing app, found in the Privacy settings, you can decide which (if any) apps use APIs to detect the state of your activity on Windows. This can significantly enhance privacy and security, as you can have apps containing sensitive data lock automatically when unattended. If you’re a laptop user, it can also be beneficial to your battery life.

• Bluetooth LE. Microsoft is adding support for Bluetooth Low Energy, a functionality that allows reduced battery consumption when devices are connected.
  
• Adding more languages to the Live Captions feature. This specification is only as powerful as the languages it supports. Microsoft is reportedly working on expanding the list with 10 more languages.

Summary

We’ve got some interesting stuff to look forward to with the next major Windows 11 update. And these are just the things the Internet’s actually heard of, so who knows what else Microsoft might be planning? It remains to be seen, hopefully just a few months from now. 23H2 has been released on October 31st.

Windows users need to be on high alert. Microsoft has confirmed a critical vulnerability has been found in all versions of Windows which presents an immediate threat, and you need to act now. A critical new zero-day hack has been found which affects all Windows versions. Tracked as CVE-2021-34484, the “zero-day” flaw enables hackers to breach all versions of Windows (including Windows 10, Windows 11, and Windows Server 2022) and take control of your computer. Microsoft mistakenly thought it had patched the vulnerability (which was first found in August) when it was publicly disclosed in October. But the fix itself was found to be flawed, something the company admitted, and this drew even more attention to the vulnerability. Microsoft subsequently promised to “take appropriate action to keep customers protected” but two weeks later, a new fix has still not arrived. Luckily the third-party security specialist 0patch has beaten Microsoft to the punch with a ‘micropatch that it has now made available for all Windows users “Micropatches for this vulnerability will be free until Microsoft has issued an official fix," 0patch confirmed. You will need to register for a 0patch account and install its download agent before the fix can be applied, but with 0patch fast becoming a go-to destination for hot fixes which beat software companies to the punch this is a no brainer. Hopes will be high that Microsoft can release an effective patch sooner rather than later but, until then, all Windows users must act now if they want to be safe.

Microsoft Edge may be about to win a lot of fans by introducing a new feature that it says could prevent one of the most annoying things about being online. A new update to the browser suggests it is looking at a way to block auto-playing videos by default when a user navigates to a website. People spotted a new entry to the Microsoft Edge Canary browser where the company tries out its in-progress updates, that suggests auto-playing videos may have had their day at last. The new addition, for Mac, Windows, and Linux systems, is called “Autoplay Limit Default Setting”, with the description suggesting that Microsoft Edge would set the media autoplay setting to "Limit" as a default - stopping videos from starting up when a user lands on a website. Currently, Edge offers two options for users to control media autoplay - "Allow" (the current default setting), where all videos on a website will play automatically with sound, and "Limit", where media won’t be autoplayed on sites that a user has previously visited. It appears that Microsoft is looking to test the feature in Canary before rolling it out to a wider user base - as blocking autoplaying videos can cause issues for some websites. The same Canary entry also hints at a future "Block" option, which would presumably stop any videos or media from playing when a user lands on a website. However, this feature, which is also listed as being available for Mac, Windows, and Linux systems, doesn't appear to be enabled as yet.
