It has been a busy time in Redmond. Three hundred and two days ago, on September 30, 2014, Windows 10 was announced by Microsoft. The name, at the time, was a bit of a surprise, and Windows 10 was born out of the ashes of Windows 8.1. Over the last three hundred days, we have seen a pronounced change in how Microsoft develops software. Windows 8 was the crowning achievement of Steven Sinofsky, and his sudden departure from the Redmond company only weeks after Windows 8 shipped perhaps signaled that Microsoft knew out of the gate that Windows 8 would be controversial and difficult to adopt for their core user group. A new direction was necessary.

And so we have Windows 10. Separated from Windows 8 by more than just a number, it was also forged by a Microsoft who was more open about the development process than I can ever recall. The day after Windows 10 was announced, Microsoft opened up the Windows Insider program, to give anyone who wanted a look at the new take on Windows to give it a spin, and not only that, they could offer feedback and suggestions for apps and features. The changes made to Windows 10 over the last three hundred odd days, have been dramatic, which is a testament to how the new Microsoft takes and processes the huge amount of feedback it received.

The Windows Insider program was very successful. Very quickly the number of people who had signed up was over a million, and the last count that I saw was that there are over five million people in the Windows Insider program. The response has certainly been enthusiastic.

Of course it helps that the software being tested showed that Microsoft was listening well before the Insider Program even began. Windows 8’s biggest pain points, such as the Start Screen, full screen apps, and the Charms bar, were not going to be tweaked in this release, but completely done away with. Back was the Start Menu, back was windowed apps, and back was what made Windows, well, Windows. Where Windows 8 was promoted as touch-first, Windows 10 was created as productivity first, with the OS trying to assist you with things like Snap Assist rather than get in your way.

There is a lot of changes and features to go over, and in typical AnandTech style, we are going to provide as much information about each as we can. I wanted to ensure that we did the review with the final code, to ensure any of our tests would be accurate and real-world results. Hopefully the full review is worth the wait.

With Windows 10 being the first ever free upgrade, here is a quick look at what to expect if you signed up to get the upgrade on day one.

Windows 10 gains a personal assistant in Cortana. What originally launched on Windows Phone has been brought to the PC, and it can now work across all of your Windows devices. One of the key benefits of Windows 10 over Windows 8 is that features like Cortana are easily discoverable. Cortana now lives in a search box right beside the start button, and it can keep track of your travel plans, set up reminders, and perform searches for you.

Microsoft is also adding a new browser to Windows 10, with Microsoft Edge. Although based on Internet Explorer under the hood, huge chunks of code have been taken out to improve security, and the rendering and scripting engines have been optimized to make Edge one of the fastest browsers around. It adds support for new features like being able to markup web pages and share them, and Cortana is built in to provide contextual search results right in the page. It is a big step up from Internet Explorer in standards compliance, and while it’s not quite finished yet, Microsoft has promised to update it often through the Windows Store.

With Windows 8, Microsoft basically built a tablet operating system, and stuck the desktop inside of it. I actually quite liked the design when using Windows 8 with touch, but using it on a large screen desktop could be frustrating. Windows 10 is still designed for both systems, but they have added Continuum to Windows 10 to automatically prompt to switch from one mode to the other. Optimizing Windows for what you are doing is a much better approach than optimizing for what you’re not doing, and Continuum finally bridges the gap between desktop and tablet on one device.

Gaming is getting a big boost on Windows 10, with support for DirectX 12 which is the biggest change to their gaming APIs since DirectX 10 launched with Windows Vista way back in 2006. DirectX 12’s most important feature is likely its low-level API, which can provide much better performance in a lot of scenarios where developers had been CPU bound before. Graphics Processing Units are massively parallel devices, but could be bottlenecked by the API being CPU bound. DirectX 12 makes some big changes to the API to give the developers the chance to get around these bottlenecks, and the upcoming DirectX 12 games can add a level of detail that was unattainable before.

Gaming doesn’t stop there though. Windows 10 brings some other cool things to gaming on the PC. The built in Xbox app will support Game DVR, allowing you to record game sessions, edit them, and share them, all within the Xbox app. One of the coolest features coming is game streaming from an Xbox One to any Windows 10 PC, allowing you to use any PC or tablet as the display for the Xbox, as long as it is on the LAN. This isn’t new tech, but it will be built into every Windows 10 PC. Windows 10 is also going to offer cross-device gameplay, allowing you to play against people on Xbox One or Windows 10. Some games will even support starting a game on one device and finishing on the other.

The built in apps have all gotten major overhauls with Windows 10, and now work a lot better on a desktop but equally well on a touch device. Photos has gone from an almost unusable application on Windows 8 to a very nicely executed app in Windows 10. Mail has seen a huge change, and has taken cues from their purchase of Acompli, which had one of the best email apps on iOS. Maps has also gotten a big facelift, and it can sync information among all of your Windows devices. Xbox Music has been rebranded to Groove Music, and the movies app is now a movie player with the Windows Store being unified to include all purchases including movies and TV.

On the security side, Windows 10 brings a lot of features here as well. One I am very much looking forward to is Windows Hello, which will allow you to log in with supported facial recognition hardware, or fingerprint readers. Once logged in, Passport will be available as a service to allow authentication to external services, if they add support. This will leverage public-private key technology, so if a third party was able to obtain the database of passwords from a web service, they would just have your public key which is useless to them. I’ve said it before, and will say it again. Passwords have outlived their usefulness and any work to move this technology forward should be a huge benefit to everyone.

And these features are really just the tip of the iceberg, with far more available including virtual desktops, drop shadows, a new dark theme, and more. Windows 10 is a big step up from Windows 8, but also from those that hung back on Windows 7. With the free upgrade from Windows 7 or 8 being offered for a year, adoption should be strong, but time will tell. I have been running Windows 10 since October, and as my daily computer since January. It has been worth the wait.

    It's NOT free. It's a marketing con from Microsoft. I tried the other day to install it. First, with Windows 7 Professional (fully activated). Did not work. Then, I installed Windows 8 Professional upgrade on top of that(fully activated). Did not work. Supposedly, unless you have a "Windows10 App" installed, you can't get it. And getting that app it's a nightmare. Don't even try. I bet if you reached for that credit card and forked 200 bucks, you wouldn't have a problem installing it. Sad as its sounds, I used Windows 10 Insider for the last 5 months and I thought it was ( and is ) a vast improvement over Windows 8. Another 200 bucks for a "free" upgrade ? Not a chance.
    I repeat. It is NOT free. Don't believe me ? Try it.

    It is free, I am using it right now. If you can't upgrade, you have a problem that is due to Microsoft being intent on getting your money. Whether it's an activation server problem, non genuine serial, damaged file or whatever, it's not a "trick". Microsoft IS giving it away free precisely to appease all the Windows 8 haters and the cheapskates, the people still running their old OS because it works. Yes, they want people on the same platform so they can eventually offer services and such in exchange for money. They never led anyone to believe otherwise. They aren't just going to turn off someones OS or disable necessary features. Everyone would just up and move to OSX and they aren't that stupid. Future versions of windows, who can say; for now I am replying to you on my retail copy of 10 that was upgraded from 8.1. Reply

    It's NOT free. I purchased Windows 7 RETAIL, in the box, cost me 329 dollars when it came out. The upgrade should have worked with that from the start. IT DID NOT. Then, when Windows 8 came out, they had a special offer, to upgrade for 49.95, which I did. IT DID NOT WORK WITH THAT, EIGHTER. I should have smelled the red herring when I saw it. Special apps, obscure updates with obscure names such as KB followed by numbers which even if you could get, won't install.
    Same old gimmicks I've seen over the years. It's free, you see, provided you have a degree in CS, or you are lucky to have been selected BY THEM to get one. For the rest of us suckers, pony up. The Windows Insider Program ? Carrots dangled all along. To get the suckers a taste for it. When was the last time Microsoft was so generous ? If I remember correctly, NEVER. It's a marketing con. It's been done before, and it works.

    Haha, "obscure updates with obscure names such as KB followed by numbers which even if you could get, won't install." is he trolling or just a little slow? Reply

    Says another Microsoft fan boy, patrolling every day websites like these, in order to ridicule and dismiss any valid criticism. Way to go. Reply

    Why don't you explain how it's not FREE to you. I assume you can't get it to install or haven't got the upgrade notice yet. I got mine because i ran the beta and signed up as an insider.

    My wife just got her invitation today to upgrade because she "reserved" a copy when it came up in an ad. She also "upgraded from 8.1 on her Alienware 17.

    If you can't upgrade yet, it's not because they are waiting until you pay for it, that is untrue.

    TROLLING, I have a RETAIL 7 BOX right here in the closet, an OEM 7 box, and my copy of 8.1. I'll bet you they ALL upgrade. MS hasd also said SOME versions of 7 weren't ready to upgrade yet but they are working on it. I assume weird international versions. It is free because you'll still have 7 and be able to go back to it and use it even after you upgrade if you don't like the FREE version of 10. Reply
  • Valentino-835 - Friday, July 31, 2015 - link

    I live in Canada. I bought Windows 7 at a BestBuy store. I don't think they sell "weird international versions". The Windows 8 Upgrade was purchased directly from Microsoft Website. So, spare me the TROLLING nonsense. Reply

    ALSO, its free if you download and run "MediaCreationToolx86" or "MediaCreationToolx64" when you sign into your Microsoft Insider account; which LITERALLY ANYONE was allowed to sign up and get for free. Barring that you will eventually get a push notification to your Action center in 8.1 unless you have that off. It will say, "Your Upgrade is ready." Even if you cancel that, it will come up later and say "Upgrade to Windows 10" because that is how my NON computer science wife did it. Maybe you have to wait, they specifically stated they are rolling it out in stages for 2 reasons:

    To keep their servers from buckling under the download demand

    Because not all configurations that meet the requirements are bug free yet, they have to fix some things even for people whose systems meet the minimum specs because there are so many component configurations.

    Insiders get it first,

    People who reserved it aren't even supposed to be getting it quite yet but it's gone smoothley and I suppose they are ahead of schedule on those.




    Retail - (amazon, Newegg)

    People that have unvalidated configurations.

    Whenever I hear about "unvalidated configuration" I wonder what it means. Just a thought. Reply
