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.

I've seen that from a couple of other people... Not sure how I missed it. It's on a list of small updates I need to make to the article that I hope I can get to tomorrow.Cardio - Saturday, March 10, 2012 - link
I am running Win 8 CP on a new build Asus Z68, SB @4.7, a Mushkin Chronos SSD and a GTX 580.First I think this is an exceptionally well done review. It is an OS review not hardware. There is no reason to think that the OS will work differently on an AMD or an Intel anymore than win 7 did. I am pretty sure that MS knows there are AMD systems out there and is not going to release an OS that will not run properly on them, seems like that would be the best business plan. I, for one, see nothing wrong with Windows 8. It is faster than 7 and has been completely stable for me and compatible with everything I have tried with the sole exception of CPUZ and ASUS's multiple driver install program that sees it as an unknown OS. The drivers still install normally if done separately.
It is different. Most of the complaints I hear are based just on that. Personally, I wouldn't want it if it wasn't different. If you don't want it don't buy it. If you don't want to do things in a different way you sure don't have to... Windows 7 is and will still be around. All this predictable ranting is the same as happened when DOS went away and every other OS change since. I have used Win 8 enough that the changes in use are now normal and you don't have to think about it. I'm sure before RTM and there after there will be more changes. Thanks for the very nice review. I can imagine what a job it was.

"Metro is here, and if you use Windows 8 you’ll have to come to terms with it."Then I wont be using windows 8.

Am I the only one that has trouble with this? I can sign in at https://login.live.com/ and have no problems at all, so I figured that was the login info to use.I installed the Dev Preview when it was released and used a local account. But after recalling the Win8 blog post about Win Live ID syncing, I figured I'd try it before moving to the CP. So I went into the settings and selected "Switch to a Microsoft Account". Seems logical. But I was unable to log in again to the Dev Preview install. Arrrrgh!
So, I clean installed the CP and tried using the Windows Live ID login info from the beginning. I got to the desktop, but the first time I restarted the computer, I couldn't log in. I had entered my phone number and hint info, but I never saw how to enter it. And the CP certainly didn't offer to help me when I was clearly struggling. Since I didn't have a local account, I reinstalled the CP using a local account, which brings me to today.
Is my login at https://login.live.com/ the same login that I *should* be able to use for Win8? I can only assume that I'm doing something wrong, but I sure don't know what it might be.

How long is your password?Try just the first 16 characters if it's longer than that.
For whatever (REALLY STUPID) reason, it'll let you enter a password longer than that, but it only uses the first 16 as the actual password.
(See my comment two below yours, and poke around on google. It's a known issue)
If it's not longer than 16 characters... I have no idea.

Well what is a in depth when there is nothing very in depth at all. With all the systems tested here it's really a drag that you can't dig up a AMD system and the one everyone wants to see is the BD line.Most people have seen enough to say if you wanted to do a run with the new OS it would be with this cpu because of all the guesses and some beta tests that showed a marked improvement with these cpu's.
Running a bunch of lame Intel systems really makes it kind of a joke. If you did not have a good selection of different brands then why not delay it until you have enough systems to call it a in depth review instead of a who cares review. I'm sure most would say the intel's would do good and so nothing worth noting was done that would add to a lot of how much better will a radical cpu design work on it as everything points to this being a top of the list things people want to know about the new OS.
With some win8 beta tests showing a 5-10% increase I'm sure everyone that has the new BD's has been waiting to see this one over any of the no real supprise Intel lines.
As always it leaves a fairly large question mark about just what can expect from a site that has been less than honest about AMD for many years.
It's only lately I've even come back here after what went on with bad reviews and very few when AMD first put out their first FX line that was better but trying to avoid the Intel inside ads all over and great praise for Intels horrible egg cooker cpu made me stop comming here for many years. I can't understand why anyone would not put AMD's new cpus right up front with Window's 8 so we can get a good amount of data over this hugely argued point all over the web.
So no this was anything but a in depth review. It was a candy coated and/or we need to run a filler story to help the hit counter stay busy right???
Before that Pentium 4 fiasco I came here a lot.
After that I started looking at a lot of other sites where the useful data WAS useful. Intel knew what sites to throw a lot of money or inflence as they hit the top sites of the day, Tom's hardware was also doing the same line of crap and like this site I took a few years leave until they could earn back what little trust in them.
I'm sure some other sites will get the AMD BD / Win 8 test done. I can't wait to see if all the flack about AMD and windows had merrit. If not I'll stick with Win 7.
Sorry about being so glib, this IS a good site now, I just hate it when they don't pay much mind about what has been the top interest about windows 8 because AMD has a lot riding on how well their new cpu's will do with it. If it follows the beta tests it would move the AMD right up into the level of being a competitor as they are very close with current Intel cpus in some areas, even pass intel in quite a few other tests and if they see a 5 to 10% it would def. make AMD's cpu a contender. Not a top of the line one but it would put it where AMD wanted to see it run.
Now that would alone make it a in depth review..
It would even be a huge news item to run if AMD can do as well as the WIn8 beta reviews people might not bash it so much. AMD built this design for what could be a very sound call because a huge portion of computer users may or may not know is software is putting more demands, a lot of people run programs that can work very well in the multi-threaded apps as I have seen quite a few new ones use it and it will probably get more demanding use running 2-5 or more progs at the same time. AMD's new cpu does this part very very well.
Oh well, it seems like me most wanted AMD scores because it is very important towards AMD's future if they can pull the scores that the beta revew saw.
It can be compared to buying a upgraded cpu because new cpu's usually give this kind of increase from old cpu's scores and their new cpu's can do.
Still, it's got a lot of potential once people start coding prog's to work well with new cpu designs. Intel hsa had to face this when a lot of their products acted even worse than the current AMD performance numbers.
Even if I'm totally wrong about a details it's funny to read bad stuff about these cpu's. They do have some issues but for the most part they are still a very fast cpu and will run all software pretty darn fast.

This was a feature review/preview, not so much a performance review/preview. We'll be measuring performance more thoroughly when we have the RTM build in a few months.InsaneScientist - Saturday, March 10, 2012 - link
Maybe because it's an indepth article on the OS itself and not so much a re-review of every piece of hardware released in the last 5 years to see how it'll run Win 8? Sound reasonable?And no, how bulldozer improves (or doesn't) ISN'T what everyone wants... what everyone wants is to know if they'll be able to use the new interface. Talk to anyone who has any experience with Win8 - Metro WILL come up (fast), bulldozer? - not so much.
Oh, and as a side note, I can't speak for the initial release of the A64 vs P4 days, but I started coming here around the time the A64X2 and Pentium D came out, and I rather remember Anandtech calling it like it was... the performance was not too dissimilar, with the A64X2 having an advantage (sometimes a large one - occasionally a disadvantage), but the Pentium D needing and ungodly amount of power and heat to be competitive with it. They've always done a good job of calling it like it is! I've never understood where the claim that they're Intel biased comes from.
Don't get me wrong, I also want to know if it's going to help (and I really hope it does), but it's just not that important. Mostly because CPUs - both Intel's and AMD's - are generally fast enough.
To quote you: "[Bullzoder CPUs] do have some issues but for the most part they are still a very fast cpu and will run all software pretty darn fast."
Yes! That's it exactly! They're fast enough that it's no longer critical to be looking at hardware performance with a new operating system. Instead, when we look at a new operating system, we want to see... well... that operating system.
Furthermore, this isn't a final release. Software development develops features and then the feature set is locked and the codebase is optimized. So performance WILL change between now and RTM (and it would not be fair to AMD to test it now). Features, on the other hand are pretty close to final, so talking about those is fair game.
On the issues that everyone is talking about (Metro, UI, and feature changes), Andrew et al. did an excellent job, and I applaud them for that.

Have they done anything in the CP about that blasted 16 character limit on (live account linked) passwords?This is (in my opinion) by FAR the most egregious step backwards on Windows 8. Why on earth is there a limit on this? It's 2012 for crying out loud!
And the need for an "All" option (which should be the default) in search from the start screen. I'm seriously considering skipping Win8 just because of this.
I don't mind Metro much, it's not my favorite, but I can work with it... but why oh why did the search functionality have to take a step backwards after they got me hooked on it in Win7. :(
I may be able to use it with the keyboard search shortcuts you mentioned, but that's not exactly a ringing endorsement.

" In 2009, Windows 7 brought WDDM 1.1, which focused on reducing system memory usage by removing redundant data, and support for heterogeneous GPU configurations, a change that precluded modern iGPU + dGPU technologies such as NVIDIA’s Optimus."I don't think "preclude" means what you think it means
