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.

God who cares. Really? Vista wasnt called Windows 6 either. We all knew this was an incremental OS. The core components are Vista. They just trimmed some of the rough edges.danielkza - Monday, October 26, 2009 - link
Microsoft already replied to this: version 6 is kept for compatibility purposes, since pretty much everything that worked in Vista should need no changes to run in Windows 7.I see no reason to do major kernel changes on each release: they did what they had to and cleaned up the 16-bit remains in Vista, and just tweaked some rough edges for Windows 7. And it worked out pretty well: even if it's not much faster than Vista, it looks like it, and in the end, that's what matters to pretty much everyone.

I think that's pretty much the point. From a technical standpoint, it's a service pack plus GUI changes. From a marketing and user perception standpoint, there's a strong desire to move away from Vista. So, they went with Windows 7 instead of Windows Vista SP2.AnnihilatorX - Monday, October 26, 2009 - link

"you’re never going to stuff something like Windows 7 in to the performance characteristics of an 8 year-old OS that forgoes real security and predates wireless networking."This is partially true, but only because Microsoft makes it so. They release a monstrosity of an OS that runs like a dog, tell everyone it's better and faster than the previous release, and tra la la, most follow along. They could have developed an OS that was more secure, less of a performance nightmare, and satisfied the wants and needs of it's users. But that's not Microsoft's only goal. They have all sorts of other interests that get in the way of that goal, and subjugate "what is good for the user" to what MS thinks is good for MS.
Regarding pre-dating wireless networking, I hardly think that Windows XP was more than an apple in Bill's eye when the world was beginning to adopt wireless networking. Apple had the airport in 1999, and Windows XP shipped with wireless support built in.
Windows XP itself was no great performer. It only looks that way when you compare it with Vista and 7. Another inaccuracy in the article is your portrayal of Snow Leopard as a minor update compared with 7. I am still testing SL for customers, but the performance gains are incredible considering Leopard was already fast, the management tools are vastly improved, and almost all pieces have shown very nice improvements (the network-awareness is phenomenal, finding computers, printers, etc. extremely quickly, and with none of the halting behavior of Windows when navigating).
Also, you mention that XP is insecure. I totally agree with you on this. I spend a good portion of my time cleaning infections from XP machines. However, I spend just as much time (proportionally by installed base) cleaning them from Vista. Are you saying that someone who is using Windows 7, and visits the NY Times on the wrong day won't be infected? Or someone won't end up with the latest version of "Personal Antivirus Pro 2009" or some other dreck?
I would be happy if 7 doesn't suffer from these problems. That's a lot more time for me to spend with my family. But I have a feeling that the real security problems that real people face every day with XP and Vista will remain on 7. I just hope some of the better tools will be updated as well.

All this blabla about performance... both vista and 7 are at least as fast if not faster on quite a few things than XP. Its a fact. Everyone who denies this and still claims otherwise should perhaps not spend so much time with computers, as it seems it is a waste of time.As for your example with the infections of vista and 7. Yes, I'm sure he would be saying that because its true. I dont know what the fuck your people are doing with their machines, but at least a vista machine that wasnt "optimized" to become vulnerable to any type of attack, isnt going to be infected as easily as XP - ever.

Upgraded from 32-bit XP to 64-bit Windows 7 Professional for $99 in the preorder sale. I find it $99 well spent. Good price for 8 years worth of upgrades, and since I never even tried Vista due to all the horror stories and XP being "good enough" for my usage patterns (mostly RTS/TBS/MMO gaming--not the DX10 FPS stuff), I find it a HUGE change (increased performance and all) and well worth the money. Basically I got to skip the Vista generation and pay less than Vista would've cost for a similar feature set thanks to the preorder sale and move of all the important (to me) features into Pro from the overpriced Ultimate.I can see a bit why the article is so down on Windows 7, largely because of the prices available today. But at preorder prices, Windows 7 is a slam dunk. It's a shame Microsoft didn't make those the permanent upgrade pricing.

I agree. MS should have kept the Home upgrade at $50. I'm not sure who's buying Pro, since it doesn't have many more features that a home user would be interested in. Business users are going to have a volume licensed Enterprise version.Griswold - Tuesday, October 27, 2009 - link
No, business users in *general* arent going to use volume licenses.Do you really think small companies with 1-3 machines are interested in volume liceneses? No, they buy the professional version.
Certainly not the home premium one - and if its only for the XP mode that may be useful for some of their older software and doesnt require a seperate license of XP on each machine.
Genx87 - Tuesday, October 27, 2009 - link
Microsofts Volume License since Vista imo has been a clusterfuck. Requiring an on site activation server with check ins ever 6 months or the OS locks you out. That really puts a level of complexity not needed in an OT admins life. Especially with remote users who literally never touch your network for years at a time.When I make hardware purchases I do it with the OEM install.
