Today Windows 7 hits the GA or general availability milestone. That means that you’ll be able to pick up a PC with the OS pre-installed on it, or pick up a disc from your favorite virtual or bricks-and-mortar outlet. To celebrate, here are my top 7 favorite Windows 7 features.

#1 - Performance boost

Without a doubt the top Windows 7 feature for me is performance. On every system that I’ve put Windows 7 on, from monster quad core rigs to humble netbooks, I’ve seen a performance boost.

Putting numbers on this performance hike, on key metrics such as boot-up, video encoding and gaming frames per second, the boost over Vista is, on average, in the region of 10%.

In my opinion, this performance boost is Windows 7’s strongest selling point.

#2 - More restrained UAC

The User Account Control (UAC) experience under Vista was a little like being shot in the face with a shotgun filled with dialog boxes. A single simple action could unleash a barrage of warnings that left many users feeling confused, bewildered and angry.

Under Windows 7, UAC is a little more restrained, limiting prompts to specific actions. Some might argue that this decreases the security it offers, but I think that the “dialog blindness” that the old UAC caused is worse.

Another good side of the new, improved UAC is the fact that users can customize the level of warnings they receive and so set up the system to best suit their needs.

#3 - 64-bit becomes the new default

Microsoft, along with the big OEMs, are pushing 64-bit flavor of Windows harder than ever. Given that hardware, software and driver support for 64-bit is now at an all-time high, there’s very little reason for users not to migrate to 64-bit.

Within a few years I expect the Windows 7 effect to start to erode 32-bit’s strangle-hold on PCs.

#4 - Improved troubleshooting tools

When users hit a problem, what they want to do is find a solution or fix and get on with their day. To help users accomplish this, Microsoft has incorporated numerous troubleshooters into Windows 7.

No troubleshooter is perfect, but the work that Microsoft has done in Windows 7 will help many users fix problems for themselves without having to resort to tech support or trawling the web for answers.

#5 - UI improvements

No one can say that the Windows 7 UI is revolutionary, but the evolutionary changes that Microsoft has made in this new OS are almost all steps in the right direction. There are two aspects of the UI that have been tweaked:

- Helping users find the applications and documents they want to work with
- Once the user has found what they want, the UI fades into the background and allows the user to get on with things

#6 - Touch support

It’s going to be a while until the built-in touch support incorporated into Windows 7 really takes off, but there’s no doubt that Microsoft’s inclusion of support for touch-screens right into the Windows 7 OS will encourage OEMs to offer more systems with this cool feature.

#7 - XP Mode

I’m not a huge fan of the XP Mode feature available in some editions of Windows 7 that allows users to run XP within a virtual machine from the desktop. However, for those folks with specific bits of software that won’t work on a later OS, then XP Mode does offer a lifeline.

Bonus favorite feature - It’s not Vista. ‘Nuff said!

So, is it a good OS? Yes. In fact, I agree with Ed Bott when he calls the OS “impressive.” However, that said, I can’t see any really compelling reason to rush adoption. Take your time, Windows 7 will be there waiting for you 6 months of a year down the line. Over that time it’ll get better, and hardware/driver support will get better, so everyone’s a winner.

So, join the party and upgrade now, or wait and upgrade later. Or stick with what you are already running. Or go with a Mac or Linux … The choice if yours.

Microsoft is really turning up the consumer-focused volume on the Windows 7 launch on October 22 — despite the fact that the company makes a lot of money from selling Windows to business users, either via volume-license agreements and/or various other channels.

Why so much attention on retail — where Microsoft admittedly garners the least amount of Windows revenues? Microsoft officials believe if they can win over consumers with Windows 7, these consumers will push their workplaces to move to Windows 7 more quickly. There’s also, undoubtedly, a large helping of Apple envy/fear that’s part of Microsoft’s consumer push.

To kick off the launch activities, Microsoft unveiled on October 21 a number of retail deals for the product that it has forged with some of its PC partners and retail outlets. Microsoft is calling the promotion “7 Days of Windows 7.” Company officials said to expect more Windows 7 deals to be added throughout the coming week and to check back on Windows.com if you’re in the market for new hardware, upgrades, support, etc.)

Day 1 (October 22) offers include:

* Best Buy offering Full home technology remodel, handyman included. Best Buy PC Home Makeover
* HP laptop, netbook, desktop and monitor package with Windows 7. Geek Squad wireless home network with router and new PC setup is included for $1,199.00
* Dell Studio XPS 13. Save more than $100.00
* Acer AZ5610-U9072 23″ Touch All-in-One (with Windows Touch) for $880.00
* With the Buy a PC, Get a Discounted Upgrade offer, customers who buy a new PC running Windows 7 Home Premium can upgrade a Windows XP- or Windows Vista-based PC they already own with a discounted box copy of Windows 7. This offer will run through Jan. 2, 2010.
* The Windows 7 Family Pack is available tomorrow in select countries while supplies last. With this offer, consumers can buy three Upgrade licenses of Windows 7 for one price.
* The Student Offer begins tomorrow. For a limited time, the Windows 7 Student Offer gives college and university students in the U.S. and select markets worldwide the opportunity to purchase Windows 7 Home Premium Upgrade or Windows 7 Professional Upgrade for a discount.

I’m weighing which Windows 7 machine to buy and am open to suggestions. I’m looking for something that’s lightweight and very durable. (I’m actually considering buying both a netbook and a laptop, making the laptop my primary machine and the netbook what I take on the road.) I don’t care about running games. I don’t want or need touch. I do value battery life and don’t need anything flashy (though something with a little personality would be nice). Any suggestions out there?

One other note: If you’re in the New York City area on October 22, feel free to come by our post-launch party. It’s at the Antarctica Bar on Hudson and will start around 5 p.m. Lot of Microsoft bloggers — including Ed Bott of ZDNet, Paul Thurrott of the Windows SuperSite, Tom Warren of NeoWin and more will be there. We’re also expecting Most Valuable Professionals, testers, a few brave/crazy Softies and other hangers-on to show up to sample the seven beers on tap. Hope to see you there!
