To test claims of faster booting and lower memory usage in Windows 8, I installed a fresh copy of Windows 7 on each of three different computers of varying vintages—a Dell Latitude E6410 with 8GB of RAM and an SSD, a Dell Latitude D620 with 2GB of RAM and an HDD, and a lowly netbook with 1GB of RAM and an HDD. More complete specs for these systems can be found on this page, in which I discuss the computers on which I’ve been running Windows 8. Each computer had the most recent drivers for all of its hardware installed.
Startup time is defined as the amount of time between when the power button is pressed and when the Windows login screen is ready for input. POST time is defined as the amount of time between when the power button is pressed and when the “Starting Windows” boot screen first appears. After measuring all times in Windows 7, I reformatted the hard drives, installed Windows 8 and any needed drivers, and measured boot times in the same way.
Microsoft claimed that Windows 8 featured improved boot times, and that claim is definitely true—boot times vs. Windows 7 are down across the board. These reductions are due to some architectural changes that Microsoft has made—a Windows 7 shutdown would completely purge the OS and all running programs and user sessions from memory and then re-load a fresh copy at next boot. Windows 8 unloads the user session and running programs from memory, but saves the core OS to disk from RAM as it would do if the OS were hibernating. The result is a much faster startup time all around, even on mechanical HDDs. If, for whatever reason, your system doesn’t support hibernation (or if you’ve turned it off), these boot time advantages will evaporate.
But what's that, you say? How is a netbook that barely meets the minimum system requirements booting more quickly than a late-model Dell Latitude? Perhaps these numbers will clear things up:
This is one of the instances where hardware designed for Windows 8 will probably have an advantage over older hardware that has been upgraded—as you can see here, a computer’s time to POST is a larger than ever percentage of total boot time. Thanks to its newer hardware and SSD, the Latitude E6410 only takes four or five seconds (!) to boot to the login screen in Windows 8, but its nearly 22 second POST time means that both the Latitude D620 and the lowly netbook are ready to use more quickly. Systems designed for Windows 8, especially those configured to use UEFI instead of legacy BIOSes, can have drastically shorter POST times, and new computers equipped with SSDs may well go from powered-off to ready-for-input in just a few seconds.
To test claims of reduced memory usage, I took the same machines and let them idle at the desktop with only the Task Manager running. Both the Windows 7 and Windows 8 installs used the same drivers, so any background processes running on one OS were also running on the other OS.
We see marginally lower base memory usage in Windows 8 compared to Windows 7 on the two Dell laptops by a noticeable but not staggering amount. The netbook, with its 1GB of RAM, sees about the same base memory usage under both operating systems—because of the extra caching and preloading that's going on under the hood, my experience has been that Windows 6.x's memory usage increases when you give it more RAM to work with. That computers with 2GB and 8GB of RAM would have a higher base memory usage than a machine with 1GB of RAM shouldn't be surprising.
These slight savings won’t keep you from needing to upgrade your RAM if you’ve been thinking about it, but it’s impressive that Microsoft has been able to hold steady or slightly decrease the amount of RAM used in spite of the additional features (and remember, since Windows 8 includes both anti-virus and anti-spyware protection built in, these numbers should look even better after an install of Microsoft Security Essentials or another anti-virus package on the Windows 7 machines).

Good call. Will tweak.cserwin - Friday, March 9, 2012 - link
With Apples iOS, I am constantly amazed at how good the applications are. The best of them have such a higher focus on doing a job well. There is little bloat, not much feature creep... it's been really revealing with the iPad at how pleasurable it is to use good, elegant applications that do their jobs well.So, while Windows 8 as an OS may merge the desktop and tablet space, the elephant in the room seems to be the level of bloat in windows applications. Yes, a Windows 8 table would be able to run Windows applicaitons, but as a tablet user, I cannot think of a single Windows application that I would actually like to run on a tablet.
Until application develpers start developing applications that can deliver satisfactory experiences in both workstation and tablet usage models, the common OS doesn't do much.
While windows 8 gets to a unified OS ahead of OSX and iOS, with apple there is the full iLife and iWork suite, not ot mention 3rd part apps (photoshop, sketchbookpro, etc.).
It's going to be interesting to see these things play out. Microsoft seems to be banking on 'if you build it they will come'. But apple has the tablet user base, and that's where the developers are going to go.

I'll follow up with a question -What is Microsoft doing to help developers improve their applications to provide value in both tablet and workstation usage models?
I'd be interested in an article that addressed this.

Sure! I'm paying attention to the comments to shape the sort of things we look at in the RTM article, and we'll be able to say a bit more about Metro apps when we've actually got some ready-for-primetime products to evaluate.Off-hand, I'd suggest that one theoretical value-add is the ability to run the same app with the same features on both tablets and PCs - this can create more consistency and predictability for users, and frees developers from having to maintain an app for Metro and an app for the desktop.

Here's something for your RTM article. Sit someone's non-techie mother* down in front of a Win8 desktop PC with no prompting or instructions except to use it like normal.Someone with no prior Metro experience, no Microsoft Account, no touchscreen. Someone who doesn't have any keyboard commands memorized. Someone just like the millions of normal folks who will be buying Win8 PCs cold and taking them home soon.
*no insult towards mothers intended

This is exactly what I have been doing with folks and its been carnage.Apple must think its going to clean up when folks go to buy their next PC in 12 months time.
The stink of Vista still hangs around with folks and MS cant afford another FU like that.
Thats why W7 was so good as it looked like MS was listening to customers at last.
Metro looks like it was designed by hipsters for hipsters.

Metro looks like it was designed by "people who think they are" hipsters for "people who think they are" hipsters.there, fixed that for ya.

Apple has the tablet userbase, but Microsoft has the desktop/laptop userbase, and one of it's goals with Win8/Metro/WinRT is to attracted devs with its desktop marketshare and then grow tablet marketshare from there.I completely agree that the Windows Store is one of the biggest wildcards in Windows 8 right now, and it's one we know the least about - we won't know if it's going to attract developers and succeed until it attracts developers and succeeds. :-)

iOS on Tablets will soon get what it deserves: about 15-20% of the market, so you better compare Windows to Android.PS
"Higher focus", eh?
And iTunes is a great program, I guess...

Who was the first to have a tablet out in the market? It was NOT Apple. I have a Motion Computing LS800 tablet in my office that's older than any tablet from Apple. Yes, Apples IPAD is the reason for sparking the tablet market to what it is today, but tablet PC's have been used in health care and education industries for more than 10 years before now. I'm not disputing Apples IPad has created tremendous growth/opportunity for other tablet makers, but lets not overlook the truth to feed Apples ego.Truth/accuracy in all media please.
"In 1989, the GRiD GRiDPad was released. In 1991, there was the GO PenPoint. In 1992, Microsoft released Microsoft Windows for Pen Computing, which had an API that developers could use to create pen-enabled applications. In 1993, a smaller device that you are more likely to have seen or read about was released—the Apple Newton"
