Network Streaming Performance - Netflix
The drivers for the Intel HD 4000 enable hardware accelerated decode and rendering for Netflix streams in Silverlight on Windows 7. The Windows 8 Netflix app has been a bit of a mystery where it is not readily evident as to whether hardware acceleration is present or not, and whether it is being really utilized. In this section, we will take a look at how Netflix behaves on Windows 7 and Windows 8. The ISP at my location is Comcast, and unfortunately, there is no access to the Netflix 5 Mbps Super HD streams yet.
Netflix on Windows 7
On Windows 7, Netflix needs the Silverlight plug-in to be installed. We played back our standard test stream using Internet Explorer.
The Silverlight plug-in attempts GPU acceleration and enables it on our system. Manual stream selection is available. The maximum playback quality has a bitrate of 64 kbps for the audio and 3 Mbps for the video.
We will take a look at the efficiency of the system while playing back the stream towards the end of this section.
Netflix on Windows 8
On Windows 8, Netflix is streamed through a Metro app. Fortunately, the same debug shortcut keys used in the Silverlight version work here too. A nice add-on touch is that the manual stream selection and playback statistics OSD can be made to appear simultaneously.
It is not immediately evident as to whether hardware acceleration is being utilized or not. However, the aspect which stands out immediately is the fact that the video playback bitrate can go as high as 3.85 Mbps. Audio still remains at a lowly 64 kbps. Hopefully, a future update to the Netflix app can provide us with the soundtracks available on specialized media streamers.
Netflix Power Consumption - Windows 7 vs Windows 8
While the Silverlight plug-in OSD helpfully reports that GPU acceleration is being taken advantage of, it doesn't indicate the efficiency in any way. On the other hand, the Windows 8 app doesn't report GPU acceleration status at all. To determine the actual efficiency of Netflix playback, we recorded power consumption at the wall for both scenarios over a 10 minute interval during the middle of the stream.
The graph presents some very interesting results. With Windows 8, the system consumes much less power and the stream is also of higher quality. GPU acceleration in the app makes the streaming more than 30% efficient when compared to the Silverlight version. Compared to Windows 7 Silverlight, the Netflix app is efficient by approximately 35%. Windows 8, by itself, seems to consume less power too. Considering these results, if Netflix forms any part of your HTPC usage scenario, it is a no-brainer to upgrade from Windows 7 to Windows 8.

I have no issues with Win8. The desktop experience is virtually no different than the Win7 experience for me, I have no had any program or driver issues and the few things that are changed are for the better (the copy dialogue being the one I love the most).I'm not saying you have to like Win8, but I don't see the downsides personally. :)

So... you're KNOWINGLY refusing business. I would instantly walk out and never use you or your services again.When you're out of a job please return here.

As a network admin I was horrified to find out that Server 2012 shares the Window 8 interface.As an IT professional I have better things to do than be forced to re-learn how to use Windows Server because they decided to slap the goofy Win8 UI on their server products.

Having to learn new things is part of MS experience. Refreshing exams and all that.All our senior engineers are excited with Server 2012. We do a lot of Hyper-V, and improvements in management, switching between core and GUI (among other things) are considered worth the change.
It would be great if once learned stuff in IT can serve for whole professional life, but with dynamics IT have, that expectation is a bit optimistic. Being an IT professional means learning one's whole life.

And there it is. People get in to IT because they love using computers, most likely playing games on Windows. I know that's how I got into computers. But decided on a diffferent career path.But then you IT guys say to yourself "I already know how Windows works". So when it changes, man are you guys pissed because heaven forbid you actually learn something new.
I don't buy this "I used it for a few days, hated it, and reinstalled 7" crap. If you seriously can't figure out the Start Screen after a few hours, you can't adapt at all, or (more likely) never tried it and decided to h8 because that's what your buddies do.
Sure the current metro apps are bad, but the paradigm is solid. Even with mishmashed desktop, it's no different that Windows 7.

It has nothing to do with "figuring it out". I figured it out, and found that on the desktop, it's a big step backwards in usability.In my daily job, I run a dozen apps at once, and switch back and forth rapidly between them. Four web browser windows with ten tabs each. Word. Excel. Outlook. Notepad++. Call handling software. A password safe. Remote support software. A terminal app. And so on.
Windows 8 doesn't multitask well (as a UI, not the core OS) for what I do, and its multi-monitor setup is lousy. If the interface was an IMPROVEMENT, then I'd be more than willing to see it. While I skipped Vista as an OS, I migrated my whole house to Windows 7 within a month of its release. There is a difference between Win7 and Win8, and after running all of the release previews, I haven't upgraded, even though I have the licensing to do so.

So long as Win+R is still there I'll manage somehow.It's all about the CLI or launching .msc files anyway.

After using Server 2012 Essentials, I can honestly say it's not the huge deal like Win8 is.How often are you using Server as a multitasking OS, that is, running multiple apps on dual monitors, etc.? Server 2012 Essentials starts at the desktop, and stays there unless you click for the start screen; since you probably only have a dozen apps you use tops, you can have them pinned to the Taskbar or on the desktop and never worry about it again.
I dislike Win8 on the desktop, but Server 2012 works fine, and I haven't found the UI to be a pain as usage is different.

Ah, sane old Microsoft arguments, the exact same issues I commented on for windows 3 and 3.1 and 3.11. Corps don't change, or very rarely, best to suck it up and stick to an OS that works "Linux", its supported way better than windoze anyhow. stop beating yourselves up.lexluthermiester - Monday, January 21, 2013 - link
Quote "You just want an excuse to hate."Nope you got it wrong. Windows 7 is like XP, almost universally loved. I don't know anyone who doesn't like or respect 7. However, I only know ONE person who like 8. 8 Offers few REAL advantages to 7. But it does offer a lot of headaches, annoyances and inconveniences. Not to mention it's ugly as hell to look at. Windows 8 is a fail for oh so many reasons.
I think this sentiment sums it up for many; Why should we PAY to downgrade our OS to something as loathsome as Windows 8? Why should we PAY to make our computing experience more difficult and less enjoyable? Eh? Why?
