What’s New since Win 7 RC
Unlike Vista, which was furiously being developed right through SP1, there’s very little to report for Windows 7 when it comes to what has changed between the release candidate and the final version.
Internally, the issues we encountered with the RC and mentioned in our RC article have been resolved. Our stuttering HTPC no longer stutters, and Windows 7 now recognizes the JMB363 drive controller in one of our test systems correctly. At this point we have yet to encounter any issues that we can chalk up to a bug in Windows 7, which is a very promising sign.
There have been no notable changes to any of the programs or components of Windows 7 compared to the RC beyond simple bug fixes, so if you’ve use the RC then you’re going to find that the release version behaves the same way.
The only new bit of information we have is that last month Microsoft revealed that Windows 7 has greater CableCARD support, which we believe is a product of the new Protected BDA driver subsystem. Unfortunately the Digital Cable Advisor tool needed to enable this feature, and the associated firmware for the ATI Digital Cable TV Wonder (the only CableCARD tuner currently on the market) missed their release date of the 22nd, so there is no way to use this functionality at the moment. We don’t have any idea of when these will become available.
Externally, Microsoft’s hardware and software partners have been getting their houses in to order. Since the driver model s aren’t changing this time around there’s not nearly the kind of churn we saw with Vista. AMD and NVIDIA are the outliers here: they have been pushing out new drivers to support DirectCompute, Media Foundation Transcode, and the other features that are coming with 7 and/or DX11. Anti-virus vendors are the other group that stand to be most affected by the launch of 7, as they have been publishing new versions of their suites that include official support for Windows 7.
Finally, battery life, one of the sore spots with the RC, has finally gotten the kick in the pants we were expecting to see. We’ll get deeper in to this later when we look at benchmarks, but for the time being we’ll note that while the RC offered a battery life similar to Vista, the release version of Windows 7 offers battery life well ahead of Vista in all cases, and depending on the exact hardware used similar to if not better than battery life as compared to XP. It looks like Microsoft and driver authors have finally come through on significantly improving Vista’s lackluster mobile performance.

I should also mention that Win7 has a lot more features available to developers such as a biometric and touch screen support. The touch support is already being used by HP on their touchsmart computers.I think the fact that Win7 was such a modest update (compared to the XP to Vista transition) is why its been getting such great reviews. Vista SP2 is a solid OS, and to depart too far from that would be risky.
I used Vista when it first came out and it had terrible disk performance and buggy drivers... I can see why people didn't like it. Since SP1 its been a pretty solid, fast OS. However its never been able to recover its tarnished reputation.

"On a proper system, Vista has always been the better choice for Windows."Oh really? Why did so many people decide to stick with XP then?
"If you’re not on Windows Vista or Windows 7, you should be. XP has been outdated for quite some time."
XP runs every program I have just fine. Just because it's outdated doesn't mean it can't be used. I'll decide what OS to run on my computer, thx.

Well, then you really didn't need to read the article for advice, did you?That statement was probably poorly worded, as at Vista launch there were definitely reasons to stick with XP, and I'd guess there are a decent number of people like me, who skipped Vista as by the time SP1 was out, it was known that 7 would be coming soon and not to bother stopping at Vista in between.

On the laptop page, should that be "second to resume from hibernate"? If not, then I dont think its really that important a statistic, I'd be happy for my Desktop to take twice as long to hibernate, if it resumed in half the time :)drfelip - Monday, October 26, 2009 - link
What about the performance benefit of SSDs under Windows 7? I think this is going to be my next upgrade.Voo - Monday, October 26, 2009 - link
I switched from XP to 7 when I got my free RTM from MSDNA and have been using it since then. Imho the usability improvements (new taskbar, search, that neat window snap stuff,..) and the overall look are really worth the upgrade and I'd buy the retail version anytime.I also took the chance to get a Intel SSD, so I'd have to install the OS in any case.. win/win situation ;)
XP was nice while it lasted, but it shows its age and XP64 was never really up to top, so it was just time to change.

I have to COMPLETELY disagree about OS X having the better interface. At best, it's personal preference, but I can think of a ton of examples where Windows-even older versions of Windows-have a more logical way of doing things. (Just two examples-it's much easier to create/manage files from Explorer, whereas OS X more forces you to use the program you want, and then save the file out through the program-Windows does either way almost equally well. Another-save dialog boxes in Windows have long had FAR more functionality with being able to manage other files while saving-something I end up making use of near daily.)OS X's font rendering continues to be horrific too, and it STILL doesn't play Blu Rays!
But...I do like the changes made to the task bar on Windows 7, for the most part. It mostly is a "best of both worlds" approach, although it doesn't do EVERYTHING as well as what it's replacing. (I miss the classic Start Menu too, which had more functionality than the new one, but some of the new Taskbar changes help mitigate that.)
I'm glad Anandtech continues to champion UAC. One of the first things I did after installing 7 was to change it back to it's highest setting. I'm baffled by the resistance to it. For one thing, OS X has done THE SAME THING since it's inception-which is a GOOD thing. For another, you don't see it very often, and we should all want that extra layer of security.
I've seen a self professed "computer expert" going on about how *HE* doesn't need UAC-and completely not getting it that we probably benefit MORE from it than the average user, since we know if something we're doing would need to have prompted that. He wasn't getting it that it's a protection from malware, etc.

I have to confess, even tough I like the UAC idea, I could not stand it in Vista: the protection did not make up for the annoyance.But I've been using it in Windows 7 since January, and I have no complaints whatsoever: being a power user, knowing what the (tons of) diff. programs are up to is incredibly helpful.

I completely disagree with a lot of the conclusions in this article. I think Anandtech is a little blind to the performance benefits of Windows 7 over Windows Vista because all the equipment they use for testing is brand new and high end. The bulk of laptop users have machines that cost $800 or less. In the last year Netbook sales and lower end laptops have become the norm. This review completely ignores those changes in the market place. I have installed Windows 7 on lots of lower end laptops that previously had Vista and in 100 percent of the cases the users have commented on how much faster Windows 7 feels.If your an HTPC user then Windows 7 is a must IMHO. I've been using 7 since January and I have yet to see a BSOD. I definitely can't say the same for my Vista machine (it's 7 now too).

I agree, I think this article is incomplete for the most part. As I commented on the 2nd page Tom's hardware does have some sort of test for this. I don't know because I only read the conclusion. They seem to be in agreement with us about Windows 7 being good on older PCs, especially laptops.I've converted many laptops as well and they are definitely running better with Windows 7.
