Windows Recovery Environment
The Windows Recovery Environment, or WinRE, has actually been around for awhile. It was first introduced in Windows Vista as a basic boot environment from which users could run tools like System Restore, Startup Repair, and the Command Prompt, and it could also restore a complete OS image created by Windows Backup.
This menu remained basically unchanged in Windows 7, but in Windows 8 it picks up Metro styling and also replaces the text-based menu that appears when you press F8 at Windows startup, one of the last bastions of the Windows 9x/NT era to make it into 2012 relatively unchanged.
The new graphical menu presents all of the same options as the old WinRE, as well as access to the new Refresh and Reset functionality—the main difference is that options for booting into Safe Mode are buried in the Advanced Options rather than coming up right when you press F8. When you choose a function like System Restore, the desktop-style tools included in Windows Vista and Windows 7 will pop up and walk you the rest of the way through the process. Most of the troubleshooting options require you to input the name and password for an administrator on the computer, to prevent tampering.
There’s nothing groundbreaking here, but the Metro styling is functional and attractive. See the screenshot gallery below for more.
Secure Boot and UEFI Support
After Metro, this is probably one of Windows 8's more misunderstood features, so let's try to break it down and demystify it: UEFI (Unified Extensible Firmware Interface) is a replacement for the legacy BIOS found in most PCs. UEFI support has been around in the 64-bit versions of Windows since Vista, but it has only recently started to see wider adoption in PCs. In addition to being more modern and flexible than BIOS, UEFI supports a feature called Secure Boot, which can compare signatures in drivers, OS loaders, and other things against security certificates stored in firmware to verify that your computer is using a known safe bootloader rather than a malware bootloader. On both ARM and x64 computers certified for Windows 8, Secure Boot will be enabled by default to prevent these potential exploits. Note that this is an extremely brief overview of the functionality—you can read more on the Building Windows 8 blog if you’re interested.
Now, the problem people have with this new feature is that it can potentially be used to block any non-Windows bootloader from functioning, including those used in operating systems like Linux. By default, this is true, but you’ve got an out: in all x86-based Windows systems that ship with Windows 8, you should be able to add and remove security certificates from UEFI as needed (thus adding certificates that Linux needs to be recognized as a trusted operating system) or disabling secure boot entirely (making the Windows 8 PC act more or less like most Windows 7 PCs do now).
This will be slightly different for Windows on ARM—WOA systems will also support UEFI and thus the Secure Boot feature, but users won’t be allowed to add certificates or disable the feature, and OEMs will be disallowed from shipping updates or tools that unlock the bootloader (as some Android tablet makers have been known to do). You might not like this behavior, but the fact remains that this is how the vast majority of ARM devices work today. Linux advocates act as though Microsoft has taken something away in disallowing third-party OSes on WOA devices, when in fact they’re disabling nothing that hasn’t already been disabled on most competing tablets.

Very annoying till I went through Microsoft Help and discovered I will not be able to "snap" apps with my standard 4:3, 1280x1024 screen. boofRESHOiL - Monday, March 12, 2012 - link
This time around they added a great setting "Make Everything on my Screen Bigger".I didn't have to mess with loading my custom fonts, sizes, DPI, etc. to make my system visible from my couch on my 56" DLP. It did seem to make Metro Apps bigger but not desktop apps or the desktop experience.
Also, I've gone through a ton of small media keyboards and none are as easy as my remote. Since Metro, and all tablet/phone OSes are more geared towards consuming media/data rather than creating it... not saying they can't, but they do better at consuming, I thought for sure they would have accepted windows remote control commands in all the Metro Apps, to my surprise not one does. Of course the arrow keys and OK/Enter key work, but Info, Back, etc have no function in Metro Apps. Just a few changes and Metro becomes the best 10' full OS ever, mainly that it needs to work with remotes. Also, Media Center hasn't changed at all... I think it could use a little Metro and hope it does get it in the final product.

I wonder how your video playback batter test would perform with well encoded HD videos with hardware-accelerated playback...I'm sure most of you guys know all about video encoding and decoding... GPU video decoding (my personal experience) consumes a LOT less power than software decoding done on the CPU. Yes, GPUs generally consume more power than the CPU, but it's a lot easier for the GPU to decode Full-HD videos than it is for the CPU (by an order of magnitude), also arguably more efficient.
We all know that hardware-accelerated video players (MPC-HC and Windows Media Player included) support that feature. But you never mentioned if it was enabled in your setup. So I'm assuming you didn't use any sort of HW Acceleration, and therefore, you had 2 or more cores of your test setups running in each test for decoding the video while playing the videos.
On my HP DV6 Core2Due T6400 laptop, properly encoded MP4 videos run with almost 0% of CPU utilization, and with the right codec (I use the FFDShow with DirectX Video Acceleration) even high profile MKV files run with 5-15% cpu utilization (otherwise 50-100% of CPU utilization. I use Windows Media Player since it doesn't utilize as much CPU power as MPC-HC.
My laptop stays 2-2.5 hours on battery if i'm using software decoding, but lasts well above 3.5 hours with HW-Acceleration enabled... I wonder how that will affect your setup?

I'm glad the reviewers found some redeeming qualities to the OS. All I can say is that I was not impressed with MS' mobile OS. It's strong in concept but just tacky in appearance, like some city traffic symbol maker was in charge of the design. Windows 8 does no better IMHO and this honestly looks like a crap sandwich waiting to blow up in MS' face. Serious? "It's very useful once you learn all of the 50+ new keyboard commands!" You have to be kidding me. I know you all are hardcore nerds here working at Anandtech but there is a reason W8 is getting slapped silly in the consumer oriented reviews. I saw a review the other day that quite literally said, "I enjoyed the review of Windows 8 so much I order a 21" iMac." Tempered indeed.FuzzDad - Monday, March 12, 2012 - link
No issues with SLI, my watercooling programs...my configs for gaming...the install went solid. I have a mouse locking problem with Logitech keyboards but there's a work-around until they fix it. I didn't like the interface at first (it isn't intuitive) but once you get to the point where you accept Metro=Start Button it all kinda makes sense. I think the GUI is snappy and smooth and it grows on you. I also think they're probably writing off Windows 8 for the desktop/business use...unless they throw the start button on there...and only after that would there be any talk of it going widespread on desktops that have not yet moved to Win7.I think their strategy is simply get back to a three-year release schedule and into the tablet space as quickly as they can. TBH...this OS is as good as Win7 w/new interface...if they had offered the start button as a hard-core option I think all the howling winds we hear now would have been a soft sea breeze.

...who exactly is going to buy a Windows based Tablet?It's way too late surely? It's the Zune all over again.
The Corp bosses will all have iPads so will be pushing to use them in their work surely? The iPhone through this method is now becoming the standard corp phone of choice at the cost of BB.
MS isnt going to get a look in on this one.
I am a Zune Mk1 owner, just in case.

you'll be surprised how many people there are who didn't go with the hype and rejected iPads and Android tablets just because they're not "Windows"....What's amazing about this release is the first impression i heard from lots of people who saw it on my laptop. Lots of them said the very same thing: "Wow, Windows now has *windows*! Everything is in front of me an I don't have to look for anything!"... i haven't noticed that myself, but surely, what they said was true.

"you'll be surprised how many people there are who didn't go with the hype and rejected iPads and Android tablets just because they're not "Windows"...."Well good luck to the three of you I say.

Great article, the efforts of the whole team come through in the depth and quality of the report and I'm looking forward to reading the follow-up articles.I use Windows 7 every day to get real work done.
I'd appreciate any feedback from the team (or other AT readers) on the following question: Will the UI enhancements in Windows 8 offer any benefit to me? Specifically, is there anything in Win8 that will help me be more productive in my daily use cases?
On my multi-monitor primary workstation I have the Win7 start menu running vertically on the side of one of my monitors. I often have 3 "pages" on my taskbar of windows open between: outlook, word, excel, powerpoint, firefox, PDF files, text files, explorer windows, putty sessions, and skype or MSN chat windows.
In other words, I am doing a lot of multi-tasking and waste a lot of time doing context switches as needed. Even with 2 or more monitors available, I never have enough screen real estate to have all of the various applications and windows open without ever needing to re-arrange all of the windows.
Win7 provided marginal improvements over XP, I especially like the ability to quickly snap a window to the left or right half of a given monitor. I wish MS would have expanded on this to allow me to snap to the top and bottom halves as well.
I've used a number of 3rd party applications over the years to enhance window management, but invariably they end up either being clunky, unstable or requiring so much additional effort to negate the goal of improving productivity.
Does Windows 8 actually add anything to make window management better/easier/faster/more powerful for those of us that are really multi-tasking all day? Metro seems to be completely consumer focused, what about the professional users?

I've tested it, I don't think you'll find improvement for your usage scenario. In fact it can actually slow you down because they remove Start button. If you want to launch normal desktop apps quickly, you basically have to pin them to taskbar from Metro UI, or use the same enabling-Quick Launch bar trick that people use when they went from XP/Vista to Win 7. There are also third party programs such as Start8 that can bring the Start button back.I find it ironic that people have to use third party program for basic functions to circumvent Microsoft's devolution in UI scheme or stubbornness. I have to use a third party program to enable hovering scrolling in different panes in Windows Explorer (it's still not there in Windows 8).
There are so many ways they can improve desktop UI that I can list that would put OS X to shame, and you even suggest the horizontal snap that can improve desktop usage that many people would probably use. Unfortunately, they're too busy toying with Metro UI. I've always thought Microsoft is a company good at software engineering, but bad at user interface.
