Ballmer says Windows 8 is a big risk for Microsoft
We know Microsoft is not afraid of taking risks, even when it brings ridicule. I've said it before and I'll say it again -- although Vista (pre-SP1) earned a bad reputation for a variety of valid reasons, it was a necessary risk that Microsoft took to provide better security now, in Windows 7, which is built on Vista. Meanwhile, Vista will go down in history as one of the worst OS releases due mainly to a media frenzy launched by InfoWorld that trashed the OS mercilessly and an inexperienced public that bought into the negative press.

Is that what Ballmer is referring to when he says the next version of Windows is risky? Will Windows 8 be the next OS to take a bullet for the future of computing that we'll embrace with the Windows 9 to follow? Hopefully, history won't repeat itself so soon.
One thought is that Windows 8 will be only x64 and x128 (yes, you heard me), positioning Windows 7 as the last 32-bit OS. As crazy as that sounds, everything moves forward eventually. It wouldn't surprise me if the next flavor of Windows is 64-bit only. If it offers a 128-bit flavor, that would ensure Windows 9 will fully support 128. But this doesn't seem to be the big "risk" that Ballmer hinted at.
I'm more inclined, and excited, to think that the risk that Ballmer is speaking of relates to features. It's obvious the economy may not be ready for a new version of Windows that might require enterprises to spend money on more hardware upgrades. Also, those who upgraded from Windows XP to Windows 7 will not be eager to move to Windows 8 unless the features are compelling enough.
I believe the big risk Ballmer hinted at is whether the release will be significant enough to encourage the transition for XP stragglers and Windows 7 users alike. Given how good Windows 7 is, I'd have to be really impressed to make that move personally.
What Windows 8 may feature
What are the rumored enhancements? PC World reports three potential form factor "center of gravities" related to "lap PCs" and tablets, workhorse PCs, and family hub PCs. The lap PC will have tablet features, the workhorse PC is the traditional desktop or laptop system, and the family hub PC is your next evolution of Windows Media Center, where it ties your TV and other media devices.
One possible feature is called "My PC Knows Me," which will use a proximity sensor to detect your movements in a room and, for example, wake up your PC. When you sit at your system, it will scan your face and log you in. Multiple user accounts won't be a problem -- it will instead switch between users. I see this as an interesting parental control. Even if Junior discovers Mom's username and password, he won't be able to get around the facial-recognition-based parental controls.
Another new feature in Windows will be the equivalent of Apple's forthcoming Mac App Store or the iTunes store. Microsoft has already been working on this with Windows 7 and Vista in the form of the Games for Windows Marketplace, which is installed in PCs via Windows Update and will roll out in mid-November.
With the recent emphasis on Office 365, the productivity-oriented successor to Microsoft's Business Productivity Online Standard Suite (BPOS) cloud server suite that integrates with Windows Small Business Server 2011 Essentials (code-named Aurora), it is logical to imagine tight integration with Windows 8 as well. Some rumors say Microsoft will call its next operating system "Windows 365," which would further support the speculation that the desktop will be linked to its cloud offering.
One rumored change for Windows 8 is in the updating of key kernel OS files through the cloud servers. In doing so, Microsoft could ensure systems are updated (supposedly without reboot) with the enhanced files. Plus, this could help prevent piracy. In the event a connection with the Internet is broken, backup kernel files will be used until the Internet connection can be reestablished.
What else? According to leaked documents, as reported by Computerworld's Preston Gralla, we can look forward to improved energy efficiency, faster startup, and better help and support (although you don't have to read leaked documents to expect those updates). A push-button reset is mentioned, which would allow you to reinstall Windows without losing documents and applications. There is also mention of enhanced identity management that allows user identities to exist in the cloud and move with users as they go from PC to PC. These, too, are not incredibly futuristic in nature and should almost be expected in the next version of Windows.
My advice to Redmond: Take your time on this one. Windows 7 is doing just fine in the marketplace. Windows XP is slowly being retired where budgets and workload needs allow. The damaged reputation over Vista (earned or not) is beginning to fade, just as it did for Windows ME before it. Make sure the next flavor of Windows gets our mouths watering. Delay the release for as long as necessary until that is the case. We'll wait.
Only Microsoft knows how the next version of its Windows operating system will look and what it will be called, but big changes could be ahead for the OS that observers refer to as "Windows 8." 
As for Microsoft's goal of "instant on" computing, blogger Manan Kakkar spotted a Microsoft patent for using a hypervisor-another virtualization method-to split the operating system into a general-purpose OS and a number of appliancelike applications, such as for TVs and tablets. Those uses, Kakkar says, could switch on instantly even if the core OS took 30 seconds to start up. 
Microsoft clearly wants to create an operating system that scales between devices. ARM support provides the foundation, and cloud services could be a major building block. The challenge for Microsoft will be to leave the core Windows experience and legacy compatibility intact while also pursuing its lofty ambitions. 
Just as you were getting comfortable with Windows 7, it looks like Windows 8 is coming in the next two years. In a post celebrating the one-year anniversary of Windows 7 -- the fastest selling OS in history -- Microsoft's Dutch Web site briefly mentioned the construction and release of its successor:
Reports from last year suggested Microsoft was building a 128-bit version of its OS, which could very likely be Windows 8. More recently, Network World acquired more than 15 confidential slide decks detailing possible additions, including body-sensing features similar to the Xbox Kindest, a desktop app store like Apple's forthcoming Mac App Store, near-instant CPU booting, and a focus on powering tablets.
