Windows 7 Performance Guide

Multitasking
The vast majority of our benchmarks are single task events that utilize anywhere from 23MB up to 1.4GB of memory space during the course of the benchmark. Obviously, this is not enough to fully stress test our 4GB memory configurations. We devised a benchmark that would simulate a typical home workstation and consume as much of the 4GB as possible without crashing the machine.
We start by opening a instance of Internet Explorer 8.0 with six tabs opened to flash intensive websites followed by Adobe Reader 9.1 with a rather large PDF document open, and iTunes 9 blaring the music selection of the day loudly. We then open Lightwave 3D 9.6 with our standard animation, Cinema 4D R11 with the benchmark scene, and Microsoft Word with a few large documents.
We wait two minutes for system activities to idle and then start playing Pinball Wizard via iTunes, start the render scene process in Cinema 4D R11, and then the render frame benchmark in Lightwave 3D. Our maximum memory usage during the benchmark is 3.46GB with 100% CPU utilization across all eight threads.
This a pattern that will repeat itself throughout our benchmarks. In well threaded applications, Windows 7 has a slight advantage over Vista and a larger one over XP. In this particular case, Win7 completes the benchmark nine seconds quicker than XP for a 2% advantage.

It is Vista with a facelift. If you already have Vista i agree with you. I only have Win7 thanks to my Technet account. Doubt i would pay for the upgrade from Vista.But I still think Win7 is a very kickass OS. I have been impressed. Except for the dumbing down of UAC.

If you're just going over the features, and installation of Win7 - why call it performance guide?"Intro to Win7" would be more appropriate.
We expect to see performance related GUIDES, when we saw that title.
Not just some boring and obvious old-recycled presentations the whole internet has already gone through.
So boring!

Windows 7 was released and the people with AMD systems running RAID setups were in shock, no RAID drivers for windows 7. This is an issue. Today there has been RAID drives posted at the AMD site, with the posting date back dated to the 22nd.I had tried for hours try to get this new OS installed on the 23rd, but none of the available drivers were accepted by Win7. There for I could not install with a RAID setup. After Googling for a bit I realized I was not the only one, this was a far bigger problem.
My initial excitement of enjoying the weekend with the new OS did not take place. It is now monday and I am wondering when I will take another stab at another install attempt.
The link I have found for the AMD RAID driver is

Why was this issue not covered by any review sit?

This is an AMD issue, not a Win7 issue????How is it Microsofts fault AMD dropped the ball with their RAID driver support?

"Why was this issue not covered by any review sit?"Because it's not a Windows 7 issue.

I believe you are half right.If a business runs a raid setup and most do, they can not use this.
If individuals run raid, they can not use this.
If millions of businesses and individuals can not use this. Then what good is an operating system that so many can not use. This is not good business.
The RC version worked with the existing drivers and the RTM version came with out warning that the rules had changed for this OS. The OS has changed, therefor this is an OS issue.

How many businesses do you know run RAID on their desktops? I'd like to know myself because in the thousands of workstations I have built over the past years only a handful ever used any form of RAID. And those were RAID 1 and I am convinced the engineers who ordered them only did it to say they have RAID.DominionSeraph - Monday, October 26, 2009 - link
"Certainly someone is going to bite my head off for this, but I don’t think Microsoft should have made such a fundamental change to UAC. More casual users may not have been fond of how Vista or UAC Level 3 handle security, but it was a more secure choice than Level 2."What are you doing complaining about security while running as admin?
UAC is about social engineering. That it acts like a security feature is because if you want to engineer towards the security model with limited accounts, you have to make the administrator account act like one.
The standard access tokens and UAC nags used by the administrator account are not a part of the tiered model's administrator level -- they're there to mimic the experience of a standard user account so programmers will actually program for standard user account access. (and so users will get used to the prompts for elevation that come with operating as a standard user.)
To obsess over a reduction in limited user -type security in the administrator account is to miss the point that that's not even aligned with Microsoft's security philosophy. Their model (along with everbody else) has been tiered privileges, not somehow patching all possible vulnerabilities out of root.
Vista's default UAC was pretty much universally reviled. People wanted fewer nags, meaning less limited-access -like behavior. But you can't have auto-elevation without a reduction in security.
Could Microsoft do a better job securing the hole they opened to god-mode from the administrator account? Yes. Would the amount of effort be insane, judged in light of the fact that an administrator account is supposed to be god mode? Yes.
Should Microsoft rewrite the Win7 kernel so that these apps run in protected space that restricts them to pre-authorized actions and disallows daughter processes just so the lazy and power-mad among us can dismiss the logical security scheme and continue to run as Administrators 24/7? There's always going to be system vulnerability from the administrator account -- that's kinda its purpose. Instead of trying to secure the unsecurable, Microsoft is trying to get people to embrace a better model.
And at least they took out the obvious stupidity, like MSPaint auto-elevating. (You can delete anything [like C:\WINDOWS] from its file manager when elevated.)
And, for the record, I'm one of those lazy and power-mad who run as Admin 24/7. But I'm also on a non-critical machine.

What's the big deal about out of the box codec support? Is it really that difficult to get a different media player and/or codec pack?
