• A new option for the Copilot key has been spotted in testing
• Windows 11 users are getting the ability to remap it to 'Do nothing'
• This comes on top of work already underway to redefine the key to Right Ctrl or the context menu

Microsoft's latest revolutionary idea for Windows 11 is to have a key on your keyboard which can be remapped to do absolutely nothing.

Windows Latest noticed the latest twist in the tale of the Copilot key, as highlighted by regular leaker PhantomOfEarth on X, who spotted the development hidden in a recent Windows 11 preview build.

In the choices to customize the Copilot key – which, by default, summons Windows 11's Copilot AI (of course) – there's a new option to simply 'Do nothing'.

Yes, that's correct – you can change the key to simply be a pointless piece of plastic that does precisely zip. (Or at least you'll be able to in testing, when this ability comes into play, that is, although some Windows 11 testers have reportedly seen it live in preview already).

As you may have seen earlier this year, Microsoft is working on bringing fresh options to the Copilot key that include customizing it to invoke the context (right-click) menu, and to turn it back into Right Ctrl (which was the key that the Copilot button replaced on Copilot+ laptops and some keyboards).

Analysis: do nothing, be happy

What's the point of a key that does nothing? Good question. Maybe it's the keyboard equivalent of a stress ball – you can hammer on that key as much as you want when you're really annoyed, and it won't splurge a load of characters into the document you're working on as you exorcise your frustrated demons.

Okay, so maybe not, but perhaps the idea is that this is aimed at people who really hate the Copilot key, but haven't decided what they might want to remap it to. So, they can go ahead and elect for the key to do nothing if it's accidentally hit, while they figure out what they might want to redefine in its place. That's stretching things, admittedly, but it's the best guess I have.

At any rate, it's a harmless enough option, although it feels inescapably odd to have a 'blank' key on your keyboard. How far we've fallen since the Copilot key was first revealed and trumpeted by Microsoft as the biggest thing to happen to keyboards in 30 years since the Windows key was introduced. And indeed more recently, Microsoft promoted the Copilot key as the "button you can press to fix everything", so there's some irony that it could soon (optionally) become the button you can press to fix 'nothing' in a very literal sense.

Don't forget that you don't have to wait for Microsoft's Copilot key remapping functions to arrive in the release version of Windows 11. You can use the Keyboard Manager in PowerToys to do this instead, although it'll be far neater to have these options in Windows 11's settings, of course.

Razer Kiyo V2 webcam: Two-minute review

Razer is a household name in the webcam space, with its Kiyo brand being one of the most popular choices for streamers and PC gamers. The latest Kiyo V2 is another sterling example of Razer's commitment to premium build quality and high-end components, and for the most part, it's a great product.

Delivering either 4K recording at 30 frames per second or 1080p at 60, the Kiyo V2 captures quality video with a high degree of customization via the Razer Synapse software. It's fairly pricey (don't expect to see it on our list of the best cheap webcams), but for a 4K webcam with this sort of build quality and feature set, it's actually quite competitively priced.

Coming in black, white, and pink colorways (mine is the pink 'Quartz' model), the Razer Kiyo V2 is an extremely well-constructed product. It's durable and pleasingly tactile. The base can be extended and rotated to capture the perfect angle, and it easily clasps onto any monitor; I tested it both with the two monitors in my home desktop setup and my laptop, and it snapped into place with no issues. It's a little heavy, however, so laptops with flimsier display hinges might struggle.

The design is a departure from previous Razer webcams, which typically opted for a singular large casing surrounding the lens construction. Instead, it's a smaller lens housing with an oblong body, immediately reminiscent of the Logitech MX Brio 705.

Not everything has been abandoned with this new design, however. The lens housing, like previous Kiyo models, includes a pleasingly tactile rim that can be twisted to close the built-in physical privacy shutter. I'm always a fan of privacy solutions like this, though given the large size of the glass lens face, it would've been nice to see a lens cap included to keep it dust- and scratch-free.

It would potentially be nice if the webcam could be detached from the attached mount in order to fit it to a different mount; many content creators will have their own video setups and may want to use their own camera stands. However, the mount does have a threaded screw connector on the base, letting you fit it atop most industry-standard camera mounts.

In terms of video quality, it's great. 4K video is sharp and colorful, and even zoomed in, I found I looked perfectly detailed in the footage I recorded. Color reproduction is great, and the camera performed well in a range of light conditions. Low-light performance resulted in some mild oversaturation, but I've seen worse performance in more expensive cameras. It also supports HDR, though only at 30fps even at lower resolutions.

The autofocus works well, but I found it was a little slow to adjust if I quickly moved closer or further from the camera. Having tested quite a few webcams in my time, I feel that a webcam in this price range should be a bit snappier to focus.

That big lens means that the default field of view is huge. A 93-degree FOV means that the Kiyo V2 is liable to capture not just yourself but the entire room you're in, but thankfully it's easy enough to tweak this via the zoom and crop tools in Razer's Synapse software.

On the topic of Synapse, it's still a frankly rather clunky piece of software, but for webcam users who want granular control over their hardware, it does a solid job. In addition to zoom and crop tools, you can also manually tweak the autofocus, auto exposure, and color balance.

The Kiyo V2's software-side feature set also includes a selection of AI-powered tools, which are covered prominently in the marketing material for the webcam. These include dynamic light correction and noise reduction, but these features already existed in Synapse, and to be honest, I'm not entirely clear on what AI brings to the table here.

Look, Razer: I get it. I'm sure there's tremendous pressure from your shareholders to make everything AI-powered, because it's the buzzword du jour. But anyone who actually wants AI in their webcam (for whatever inane reason) likely isn't going to be better served by the Kiyo V2 than any other cutting-edge 'AI' webcam, like the Obsbot Tiny SE.

One element that does actually benefit from the involvement of machine learning is the auto-framing feature, which uses AI-powered head-tracking to keep you in the center of the frame even if you move around. However, since the Kiyo V2 lacks a mechanized gimbal, it can't alter the frame while fully zoomed out and can only track you so far; it can keep you in center frame if you move by a foot or two, but it won't follow you around a room.

On the bright side, you don't actually have to use Synapse and the AI features at all. The Kiyo V2 works great straight out of the box; just plug in the bundled cable, and you're off to the races, assuming you're happy with the default wide-angle FOV.

Now, for the only real problem I have with the Razer Kiyo V2. It comes with a USB-C to USB-C cable in the box (the one with my review unit is pink, like the webcam itself), and as far as I can tell, you have to use this cable to access the full 4K functionality of the camera.

Considering that the cable is USB-C-exclusive, you'll need a free USB-C 3.0 port to make full use of the Kiyo V2. I tested it out with a USB-C to USB-A adapter, as well as using one of my own USB-C cables; no dice. It's frustrating, because USB-C ports can be in short supply for users connecting multiple peripherals, and the bundled cable is a bit short and inflexible.

Lastly, the built-in microphone is... fine, I guess. It's good enough for video calls, but anyone aiming to produce professional-level video content should definitely use a proper standalone microphone.

It's fair to say that the Razer Kiyo V2 deserves a spot among the best webcams on the market. There are a few niggling issues, but nothing that should ruin the experience for a gamer who wants a high-end webcam. For hardcore content creators, it remains a sound choice, but you should be aware of the downsides.

Razer Kiyo V2 webcam: Price & availability

• How much does it cost? $149.99 / £149.99 / AU$279.95
• When is it available? Available now
• Where can you get it? The US, UK, and Australia

At $149.99 / £149.99 / AU$279.95, the Razer Kiyo V2 is significantly cheaper than the brand's own older Kiyo Pro webcam. If you're looking for a high-quality 4K cam, it's not an unreasonable price.

Sure, you could easily get a cheaper 4K webcam, but you'll need to risk it on a less established brand, and you almost certainly won't be getting the same rich feature set seen in the Kiyo V2. Similarly effective models from other premium brands like Logitech and Elgato will cost a comparable amount, so I'm pleased to say that despite its reputation for pricey hardware, Razer got the price right this time around.

Razer Kiyo V2 webcam: Also consider

How I tested the Razer Kiyo V2 webcam

• Tested the webcam in video calls and recording
• Compared image quality to other webcams
• 8+ years of experience reviewing computer hardware

I replaced my usual webcam (the Insta360 Link 2 4K) with the Razer Kiyo V2 for two weeks, using it for all my normal video calls during the workday. I also tested it in various different lighting conditions by recording video separately and comparing the clips side by side. Naturally, I installed (well, reinstalled) Razer Synapse to properly test out all the software-side features as well.

I've been testing and reviewing PC hardware for more than eight years, starting at the PC-building hobbyist magazine Maximum PC before making the leap to TechRadar's computing team. I put all of my knowledge and experience behind each and every one of my product reviews, so you can be assured that you're getting an informed and bias-free judgement.

• First reviewed July 2026

Simply put, polling rate is the frequency at which data is sent between your mouse and keyboard to your computer. For many years, the standard polling rate of most gaming mice and keyboards was 1,000Hz, and that's still a setting that's available by default.

However, with the rise of competitive shooters, particularly tactical ones such as CS2, VALORANT, and Rainbow Six Siege, the pro scene needed a shift, and we saw the advancement towards 4,000Hz and 8,000Hz for "esports tech".

The best gaming keyboards and the best gaming mice are marketed for their 8K or 8,000Hz polling rates, particularly in models aimed at esports pro players. If you look at the current gear in circulation, it's easy to see how it's caught on: the Razer Viper V4 Pro, and the Logitech G Pro X2 Superstrike are recent examples of pointers, and the Razer Huntsman V3 Pro Tenkeyless, Corsair Vanguard Pro 96, and Cherry XTRFY K63W Pro Compact Ultra-Wideband for decks that tout this feature.

But does anyone really need an 8,000Hz polling rate when gaming? Do the best FPS players in the world even take advantage of it? I'm going through everything you need to know about how 8K works, the latency you can expect, impact on battery life, and all other things you need to consider when properly getting your setup ready for success.

How does polling rate affect latency?

True to its namesake, an 8K polling rate will report its position to your PC a total of 8,000 times, instead of 4,000 times or a thousand times as with 4,000Hz and 1,000Hz, respectively. An 8,000Hz polling rate responds with far lower latency than either of these two previous standards; specifically, updates are sent between a mouse or a keyboard to your computer's processor every 0.125ms, eliminating a theoretical maximum of 0.875 ms input delay, meaning a smoother cursor or movement.

The difference in response time of 0.125ms (8K), 0.25ms (4K), and 1ms (1K) can be huge when it comes to polling rate, provided you have the right hardware to properly take advantage of this. That's because an 8,000Hz polling rate can be incredibly demanding on the battery life of wireless mice and keyboards, and it's one of the main considerations as to why you may want to drop the response time down in your settings.

The drawbacks of an 8,000Hz polling rate

In brief, an 8,000Hz polling rate for your mouse and keyboard can be incredibly demanding on your computer. That includes heavy strain on even the best processors, the aforementioned heavily reduced battery life on a mouse and keyboard, and even the potential risk of micro-stuttering. As a lifelong PC gamer and a competitive shooter enthusiast who is hopelessly obsessed with VALORANT, I've seen the battery life debate happen in real-time.

I've tested and reviewed hundreds of mice and keyboards throughout my career, and one of the biggest points of contention when it comes to enabling the polling rate comes down to battery life. As an example, my favorite gaming mouse of all time is the Corsair Sabre V2 MG, an 8K-enabled gaming mouse that's built with a Magnesium Alloy frame. It weighs just 56g and features excellent skates, making it ideal for a precision heavy shooter.

As standard, via the Corsair Web Hub, this gaming mouse will run out of the box at 1,000Hz (1K), with battery life prioritized. With the pointer used as the stock, you can expect around 100 to 120 hours of play between charges. In my experience, I am charging this mouse every two weeks or so, depending on how much I'm working day-to-day, etc. However, in my many months with this mouse, I've noticed that things fall off incredibly hard with 8K enabled; my battery life tends to last only around two to three days (or one or two nights of VALORANT Competitive) before I'm reaching for the USB-C lead.

If we take 18 hours as the average battery life from the Corsair Sabre V2 MG when used in 8K mode, that's a reduction of around 85%, which is staggering. We can see a similar drop off from the most well-used new esports mice currently on the market, with the Razer Viper V4 Pro (an excellent mouse), touting up to 180 hours of playback in 1K but only 45 hours when maxed out at 8K. Similarly, while the Logitech G Pro X2 Superstrike has around a 90-hour playback at 1K, that drops down dramatically to between 20 and 35 hours at 8K. With Logitech's pointer, though, you have to factor in the strength of the haptics here, hence the rough range rather than a more exact figure.

What about the human limitations of an 8,000Hz polling rate?

Now that we've covered what an 8,000Hz polling rate is, how it works, how it compares against 1K and 4K, and the technical drawbacks, we now need to go over the human limitations with 8K. As previously mentioned, 1K means a 1ms response time, and that gets cut down to just 0.125ms with 8K, but what does that mean for a human being, and not a machine?

The average human response time is around 250-280ms; that's the time it takes to see something and physically react. I am not a pro player, but I do play video games at a high level, with a response time average of around 175ms, though I've been faster. The best esports players can eclipse this effortlessly: you only need to look as far as VALORANT and CS2 players, such as TenZ (widely considered to be among the best VALORANT players), with an average reaction time of 135ms. 100ms is even possible, even though the average tends to hover around the 150ms mark.

If we take 1K as a baseline for polling rate, that means there's an average of 150 reports between the mouse/keyboard and the processor, as you tap a key or click what you see. Taking 8K, then, sees 1,200 instances. With this information in mind, is there really much of an advantage here, even at this granular level, with the best players in the world and, conversely, the only people who would even notice a proper difference between 1K, 4K, and 8K?

Do pro players use 8,000Hz polling rates?

Considering the far lower latency, you would expect that professional esports gamers would all dial their settings to an 8,000Hz polling rate by default when playing demanding games, but that's simply not the case. If we look back at TenZ's mouse and keyboard settings when playing VALORANT, he last used the Pulsar TenZ Signature Edition mouse at 1,600 DPI, 0.24 sensitivity, and (most crucially) a 1,000Hz polling rate as standard; no 4K, and certainly no 8K enforced here.

What about a VALORANT player from the most aggressive team in the game? Then we must look at f0rsakeN from the legendary Paper Rex. He was last using the Pulsar Sustanto-X with an 800 DPI, a 0.71 sensitivity, and a 4,000Hz polling rate. Let's move away from Riot Games' shooter and instead turn our attention to Valve, then. As far as CS2 players go, few are as well-regarded in 2026 as Team Spirit's donk.

The young Russian is widely regarded as the best player in the world. Is he using an 8K polling rate for his mouse and keyboard to do this? No, while he previously used the industry standard Logitech G PRO X Superlight 2, he's now switched to a bespoke, and as of yet unreleased/prototype Zowie X Donk mouse at 800 DPI, 1.25 sensitivity, and a 1,000Hz polling rate. What about Niko? He recently had his own Razer collaboration drop, and currently uses a Razer Deathadder V4 Pro Niko Edition with an 800 DPI, 0.9 sensitivity, and a 2,000Hz polling rate.

Let's briefly look at two games for the sake of argument, and two of their respective top players. Peterbot is widely considered the best Fortnite player in the world, and he uses a Logitech G Pro X Superlight 2 at 800 DPI with a 1,000Hz polling rate. ImperialHal is among the best Apex Legends players, and the CEO (as he's known) currently uses a Finalmouse Starlight Pro with an 800 DPI, a 1.1 sensitivity, and a 1,000Hz polling rate. So, pro players simply are not using an 8,000Hz polling rate when playing, and they're simply better than the other 99.9% of players who play these games.

Is using an 8,000Hz polling rate worth it?

Based on everything I've gone through here, it becomes challenging to wholesale recommend (or actively condemn) 8K. An 8,000Hz polling rate is mechanically and technically better for how it responds between the peripheral and the machine, even if the human who presses that key or clicks the mouse ends up being the limiting factor, or bottleneck. It's the simple, undeniable truth that the saved milliseconds are (really) indistinguishable to basically everyone on the planet.

Then we get into the debate of battery life. Do you want your gaming mouse to last over 100 hours on a single charge, or just 10? That's a tough sell, considering it undercuts the primary reason to cut the cord in the first place. Then there's the massive CPU overload, game engine incompatibility (and developers and publishers are not yet gearing their software for the tech), and the variables of the hardware itself. Hardware makes the difference: TMR and Hall Effect switches and sensors will have far more of an impact than the simple reporting time between the processor and peripheral.

So why am I not fully discouraging you from using an 8,000Hz polling rate in its entirety? Because it ultimately comes down to personal preference, and to feel. If you're running one of the best gaming PCs or best gaming laptops with a high-end processor, a 4K graphics card, and a high refresh rate monitor, then, battery life aside, it doesn't really hurt to have everything cranked up and forgotten about. Are you likely to really notice it? No, but fractional optimization is still (ever so slightly) better than none in the first place.

I'm not quite cynical enough to claim that an 8,000Hz polling rate is just a marketing gimmick; however, I will say that hardware companies have gleefully exploited the ignorance of the end consumer, the simple reductionist view that a bigger number automatically means better, without looking into the nuances of the conversation. Now that's something you will be fully clued up on when considering your next keyboard or mouse.

• Users says they've observed LG gaming monitors automatically installing unwanted software on PCs
• LG's terms of service warn that conversations may be "captured and processed" on TV with the latest version of webOS
• The terms say you must now warn guests they may be recorded "in compliance with applicable wiretapping… laws"

How smart should a smart TV be? According to LG's latest TV terms and conditions, the answer is "not quite smart enough to comply with wiretapping laws", because that's now your responsibility if LG captures the voice of a guest in your house through its AI voice services. Though the situation with LG monitors appears to be even more dramatic.

As Gamers Nexus reports, some LG monitors appear to be installing adware on Windows PCs without asking for permission: in addition to the LG Monitor App Installer, they also install McAfee Scam Detector.

LG's own app requires full access to all system resources, which potentially includes all your online activity, logins, hardware, location and more — while McAfee has a long history of being installed on devices as 'bloatware', and people are not reacting positively to suddenly finding it on their PC.

Comment from r/LGOLED

There may be a perfectly innocent explanation for all of this, but when big tech firms keep getting caught doing bad things because they thought they could get away with it, it's no wonder people are assuming the worst.

Comment from r/hardware

The bit that's causing consternation regarding smart TVs is part 6(d) of the new LG Electronics terms of service, headed Voice Recognition and Privacy Compliance.

As Notebookcheck's Hannes Brecher notes, the section states that it's your responsibility "to obtain all necessary consents from any third parties whose voices may be captured by the Product and to notify household members and guests that their voices may be captured and processed, in compliance with applicable wiretapping, eavesdropping, and privacy laws."

There are three ways around that. One, you can turn off all microphone-based features. Some people won't mind that, but they can be useful — especially asking it for settings you don't know how to find.

Two, you can avoid installing the latest software — but that means you won't get any security updates, which are important (to protect your privacy, ironically, among other things).

Or you can disable your TV's connection to the internet so it can't send information back, but that obviously makes it less useful, and will also disable the voice controls anyway.

I think the terms and conditions are an attempt at corporate ass-covering rather than something sinister: the preceding paragraph talks specifically about when "a product with voice recognition functionality is used" and it's possible that "family members, guests, children, and bystanders" might be overheard; if you're choosing to activate AI-based voice features then of course voices are going to be captured and processed in order for those features to work.

At the same time, it does seem broad enough to let LG use people's voices as AI inputs, rather than just accidental capture. And in the context of what LG's doing with PC monitors (not to mention AI training's very, ahem, casual relationship with consent and copyright), that's a worry — and people online increasingly have no tolerance for anything like this, as the responses on Reddit and Gamers Nexus' original YouTube video have shown.

We've approached LG for comment on these claims, and will update the story when we hear back.

Comment from r/hardware

The gaming monitor market is filled with high-quality displays that offer enough features to provide the most immersive gaming experience. OLED monitors are right at the forefront of monitors in achieving the latter, with exceptional deep black levels thanks to their high contrast ratio.

It's not all just about the panel type, though. The display resolution, refresh rate, response times, and brightness levels all play a significant part in allowing monitors to blossom, and all of those aspects also determine pricing (outside of potential market condition changes).

That's exactly where the LG UltraGear 45GX950A-B comes into play. It's a 5K2K ultrawide OLED monitor, which means its display resolution is 5120x2160, with even sharper image quality than a 4K display. It's easily one of the best gaming monitors in 2026, and is the kind of monitor that would define an 'ultimate endgame' gaming experience in terms of visuals.

Despite the obvious and eventual GPU upgrade I'll have to make when using a 5K monitor, it hasn't stopped me from keeping my eyes peeled for it, particularly whenever it receives a significant price drop.

Fortunately, it's Prime Day, which means you can find it for $1,429.69 (was $1,999.99) on Amazon in the US, and for £1,472.49 (was £1,649) in the UK. However, the competition on the horizon is enough to make you consider waiting a little while before jumping all in on the UltraGear display.

Having used the LG UltraGear 45GS95QE OLED ultrawide — which is very similar to the GX9, with the only difference being its 3440x1440 resolution — I can say that the step up in resolution would make LG's 5K2K display worth every cent, despite its high price.

With the new Alienware AW3926QW 5K2K OLED ultrawide slated for launch by the end of June, LG's top-of-the-line monitor might have its money's worth. Thanks to the AW3926QW's 39-inch display size, there's a higher pixel density at 5K2K, meaning image quality will be much sharper than what the LG GX9 has to offer.

It is an RGB stripe tandem OLED panel, which reduces text fringing and provides significantly higher and more consistent brightness compared to other OLED monitors.

Most importantly, the big takeaway is that the AW3926QW's price is rumored to be at $1,100 (around £824 / AU$1,572). That's a very generous and affordable price tag, since other monitors with the same specifications are far more expensive.

The great thing is that more details on pricing should be coming very soon, so there's a good reason to weigh the options between the two monstrous displays.
