Microsoft's next OS is looking like Vista done right, with a smaller disk and memory footprint, faster startup, and fewer annoyances. We shouldn't see the kind of hardware incompatibilities encountered with the first version of Vista, since 7 uses much of the kernel code from the previous OS. Still, users who cling to XP will have a bigger adjustment interface-wise than those who moved to Vista.

Overall, we can comfortably say that Windows 7 is the best version of the Windows operating system to date. As we said in our beta 1 review, Windows 7 has the stability of Windows XP and the look and feel of Windows Vista. The operating system responds quickly and without hesitation and generally feels like it works nicely

The mood at Microsoft seems (understandably) high about this release. It's clear that lots of folks see this as the big, shiny band-aid for many of the Vista woes that people have been experiencing -- and in many ways, that's exactly what it is. If you're at all curious about what Microsoft has been up to, you should absolutely grab this install and take it for a spin (when you can); there is a metric ton going on here, and it's certainly worth taking a second look at. Bottom line, though? This is still Windows, and it's still got a lot of Vista in it. If you weren't feeling it the first time around, there may not be enough here to convince you otherwise. However, this is a valiant effort from Microsoft and it shows that the company does understand it's burned some bridges throughout the last three years -- this is a big step for them both in technique and tone, and that's certainly not lost on us.

As far as first impressions are concerned, the view around the AnandTech office has been positive for Windows 7. Gary is ready to replace Vista with Windows 7 on all of his systems if he had the time (and money), meanwhile Ryan's impressed but not convinced that Windows 7 will be worth the upgrade cost considering that it's a much smaller change than was Vista. Thus far anyone using it as a drop-in replacement for Vista has had no trouble adapting.

I've been using Windows 7 as my primary OS since last year and as my sole production OS since the RC hit. (At which time I upgraded my remaining XP and Vista machines to the Windows 7 RC build.) I have experienced no major hiccups during this time at all. And in treating Windows 7 as final code, I've found that it has risen to the challenge by responding like final code. It is now, in pre-release form, in roughly the same shape as is Windows Vista with SP2. And that OS first shipped over two and a half years ago. This deserves some mention and some accolades.
These are all for Release Candidate which is not-fully-optimized version. That's windows 7!!!
