The just-released Beta 1 version of Windows 7 is a solid, fast-performing, stable operating system that appears to be just about fully baked and ready for prime time. It is much further along than Windows Vista was during its initial beta phase, and it appears to be feature-complete. Based on the stability and speed of this beta, don't be surprised if Microsoft Corp. releases Windows 7 before 2010 rolls around.

The new, powered-up task bar makes an appearance for the first time in this beta, and it proves to be something of a mixed bag. As I'll explain later in this review, the task bar makes it much easier to manage and switch between open windows and applications, but it also mixes icons for launching applications with icons for managing open windows.

Note that this review covers only the features that made their debut with Beta 1 of Windows 7. For an overall review of all of Windows 7, see "Windows 7 in-depth review and video: This time Microsoft gets it right."





The new Windows task bar
The task bar, new in this beta, will no doubt be the most controversial new feature introduced in Windows 7. Gone is Quick Launch bar for launching applications that used to live at the left side of the task bar. Instead, large icons across the task bar are now used to launch applications.

By default, Internet Explorer, Windows Explorer and Windows Media Player all have icons in the task bar. You can, however, add an icon for launching any application to the task bar by dragging the program's icon to it, for example, from the Most Recently Used list on the Start menu.

Those icons do double duty because they also manage your open windows. For example, if you've already launched Internet Explorer, and you have three tabs open to three different Web sites, the Internet Explorer icon changes subtly to show three icons stacked on one another, as shown in the image above, indicating that you have three tabs open.

Hover your mouse over any of the thumbnails, and your entire desktop is taken up by that open window. Hover it over another thumbnail, and the desktop is taken up by that one. Click any of the thumbnails or open windows, and you'll go straight to that window.

When you're using stacked lists, to go to any open window, click on it in the list. To close the window, hover your mouse over it in the list, and click the red "X" that appears.

One more nice touch: When you download a file using Internet Explorer, a green bar on the icon shows you the progress of the download.

Jump lists
The task bar also makes use of another new feature that debuts in this beta -- "jump lists." A jump list is a list of actions or items associated with a particular application. To see a jump list for any application, right-click its icon in the task bar.

Typically, you'll see a history list of the most recent open files -- or Web sites, in the case of Internet Explorer -- as well as options to pin the application icon to the task bar (if you haven't already pinned it there) or unpin the application from the taskbar (if you've already pinned it there).

You can also unpin the three default task-bar icons -- Internet Explorer, Windows Explorer and Windows Media Player -- in this way.

Jump lists also make their appearance on the Start menu, in the Most Recently Used application list. A small arrow appears to the right of any application with an associated jump list. Click the arrow to see the list, then make your choice from the list.

There has also been a minor change to the Windows Shut Down button. Click an arrow to the button's right, and you get a list of shutdown options, including switching to a different user, logging off, restarting, locking the desktop, or putting your machine into sleep or hibernation mode.

The other major change to the interface in this beta is the addition of Aero Peek, a nifty little enhancement to the Aero interface introduced in Vista that lets you "peek" behind any open window to your desktop. It's far more fully featured than the Show Desktop icon that lived on the Quick Launch bar in previous versions of Windows.

Aero Peek lives as a small, rectangular area just to the right of the clock at the right edge of the task bar. When you have windows open and you mouse over the Aero Peek rectangle, all of your open windows disappear, and you see through to your desktop. But you don't see just the desktop -- you also see the outlines where each of your open windows would be.


Aero Peek makes your open windows disappear but shows their outlines on the desktop. Click to view larger image.So, for example, if you have three open windows -- one near the top of the desktop, one to the left side, and one to the right -- you would see the outlines of each of those screens. If you prefer just to see the desktop itself, with no outlines, click the Aero Peek rectangle instead of hovering your mouse over it.

Aero Peek also works in concert with the task bar. As I mentioned previously, when you hover your mouse over an application with open windows, you'll see thumbnails of the open windows, and you can preview them by hovering over any thumbnail. That's Aero Peek at work. If you turn off Aero Peek, you won't be able to see the thumbnails -- you'll only see them as a stacked list. To turn Aero Peek on and off, right-click the Aero Peek rectangle, and either check or uncheck the box next to Preview desktop.

I did experience some problems with Aero Peek and the task bar thumbnails (which are turned on when you turn on Aero Peek). They worked only intermittently, then inexplicably stopped working entirely. I fixed the problem using one of Windows' built-in troubleshooters, but I don't know what caused the issue. I haven't heard reports of this happening to other people, so it's possible that the issue was specific to my test machine.

Speed and compatibility
Microsoft set out to make sure that Windows 7 wouldn't have the same issues with hardware compatibility that Windows Vista had, and the company said that all hardware that works with Windows Vista should also work with Windows 7.

It appears that even in this beta version, that goal has been met. Windows 7 immediately recognized all the components of my Dell Inspiron E1505 without a hitch -- something that early versions of Vista had serious problems with, particularly when it came to wireless networking adapters.

And while the prebeta version of Windows 7 had problems connecting to my Linksys wireless router, this new beta version immediately recognized the router and connected to it without a problem.

I found no software problems either. Windows 7 ran every piece of software I threw at it, including not just obvious programs such as Microsoft Office, but lesser-used ones as well, such as Windows Live Sync. In addition, several antivirus applications are already compatible with Windows 7, including AVG and Kaspersky. I've been running the free version of AVG without problems.

I did, however, find an oddball problem that most likely affects very few people in the world -- and perhaps only me. I installed Windows 7 on a dual-boot machine, in which the C: drive boots to XP and the J: drive boots to Windows 7. Unaccountably, when I boot into Windows 7, Windows 7 shows the J: drive as if it were a C: drive. And the real C: drive is invisible -- it simply doesn't show up in Windows 7 at all, and I have no access to it. However, when I boot to XP, I can see both the C: and J: drives. If anyone has a solution for this, I'd appreciate hearing it -- there's a lot of disk space going to waste.

Beta operating systems typically run slower than the shipping version, but Beta 1 of Windows 7 is already surprisingly fast. It appears to be clearly faster than Vista, without delays associated with displaying menu items or boxes, launching programs, or doing other tasks.

The bottom line
This first beta of Windows 7 is a polished piece of work, with few apparent kinks to be worked out. Windows 7 is much further along at this beta stage than Windows Vista was at a similar point. In Vista's Beta 1 stage, the user interface was still being tweaked, the operating system was sluggish, and there were many hardware incompatibilities. Not so with Windows 7. Because so little has changed between the prebeta and beta versions of Windows 7, don't be surprised if Windows 7 is on a fast track to release.

That being said, the new task bar is somewhat confusing to use at first. After you live with it for a while, you get used to it doing double duty as a task launcher and windows manager. Still, it wouldn't surprise me if Microsoft tweaked it in future beta versions.

Given the beta's stability and speed, you can safely download it and use this on a test machine. As with any beta of an operating system, though, you shouldn't use it on a production machine.

Software could overshadow gadgets at the upcoming Consumer Electronics Show, with Microsoft expected to shed light on its upcoming Windows 7 OS.

The financial meltdown may also be lingering topic as tech vendors gather to flaunt products at the show in Las Vegas, hoping to show enough glitter and sparkle to bring them better fortunes in the new year. Attendees will pour over the latest technologies, including OLED (organic light-emitting diode) TVs, netbooks, smartphones, media players, and other entertainment devices.

Audiences may miss the show's perennial star, Microsoft Chairman Bill Gates, who gave his final CES speech earlier this year. Instead, Microsoft CEO Steve Ballmer will kick off the event with a keynote address on Jan. 7. He's expected to give a peek at Microsoft's Windows 7 OS, which many hope will be zippier and less resource hungry than Windows Vista.

Microsoft expects to make "significant" Windows 7 announcements, including a possible release of Windows 7 beta software. A "sneak peek" at future Microsoft Office software may also be offered.

A look at Microsoft's future software could add pep to what otherwise might turn out to be a subdued show. Attendance at CES 2009 is expected to drop as consumers and technology vendors cut spending amid the economic crisis. Hotels, which in previous years were often packed months before the show, have been offering discounted rates to fill rooms.

The Consumer Electronics Association insists that pre-registration has been strong and says it's too early to call it a quiet show. Organizers expect 130,000 attendees, said CEA spokeswoman Tara Dunion.

However, that would still be a significant drop from 144,000 attendees at CES 2007.

The prospect of a reduced audience hasn't fazed companies like Intel, Microsoft, Hewlett-Packard, IBM and Dell from showing products in or around the show. Overall, 2,700 companies will be present at various locations, including the Las Vegas Convention Center and surrounding resorts and hotels.

A standout at CES could be netbooks, small laptops used for basic applications such as Web surfing and e-mail. Intel defined the category with its Atom processor, which was then solidified by the success of Asus' Eee PC. The show could see an evolution of netbooks, with features like touch screens attracting interest. Asus will likely show a touch-screen netbook, and Intel is showing off its Convertible Classmate, a netbook with a touch screen that swivels.

Via's elusive Nano processor may also make an appearance. Rumor has it that Samsung will show its NC20 laptop based on a Nano processor.

Some of Intel's competitors, meanwhile, may try to redefine how people think of netbooks by pushing more advanced capabilities. Advanced Micro Devices and Nvidia may talk more about boosting graphics on netbooks. Freescale and Qualcomm could demonstrate netbooks with more communication-savvy chips.

Mundane laptops will also get a makeover. Expect plenty of buzz around a new Sony Vaio laptop, which the company says is "revolutionary" and will change the way users think about the products. It remains unclear if the tiny laptop is a netbook or a full-featured ultraportable. For power users, Lenovo is expected to show the ThinkPad W700DS laptop with two screens -- a first in laptops -- for people who want to perform multiple tasks at the same time.

Rounding off mobility will be smartphones with new operating systems, touchscreens and 3G connectivity. Many mobile phone companies are expected to adopt Google's Android platform, including Samsung, which may show an Android phone at CES.

Struggling smartphone maker Palm is holding a big event to announce its new Linux-based OS code-named Nova, along with new devices. The company hopes to use CES as a springboard to regain prominence in the smart phone market, where it has been eclipsed by Research In Motion and Apple.

Like past CES shows, televisions will grab the imagination of visitors as vendors fight to remain the centerpiece for home entertainment. CES 2008 saw the emergence of OLED screens with prototypes from Sony and Samsung, and CES 2009 could see further progress. In May, Sony CEO Howard Stringer said a 27-inch OLED TV would be coming, which could launch at the show.

Samsung showed a 40-inch OLED high-definition TV prototype in October, and larger screens may be on tap.

Given TV's ease of use, some may prefer these devices for Internet access in the future. With that in mind, some companies are working to merge the Internet and TV. Silicon Image will show its Allio high-definition LCD TV with a built-in PC so users can simultaneously use the TV and Internet through a split screen.

Intel will show prototype products for running mini-applications to complement TV viewing with information from the Internet. For example, widgets will allow TV watchers to talk to friends in real time or buy products advertised on TV from online stores.

The Internet also continues to shape how entertainment is delivered. Streaming media will battle Blu-ray DVD as the way to deliver entertainment and movies to end users. Having conquered HD DVD, Blu-ray still has a hurdle to pass with most players priced above US$150, so expect prices to drop at CES.

Some kinks also need to be worked out to better stream media between entertainment devices, and expect to see some improvements at the show. Tzero will demonstrate devices for wireless HDMI (high-definition multimedia interface) multimedia streaming between devices using ultrawideband (UWB) wireless technology. Tzero's technology enables uninterrupted wireless delivery of high-definition video and surround sound at a rate of 480Mbps over 20 meters, the company claims.

Users may also see progress in data transfers between PCs and devices like digital cameras with improvements in the USB 3.0 specification.

Overall, many other gadgets will be on display to enjoy over the show's four days. CES may end up being more relaxing and intimate with the floors less crowded.

The Engineering Windows 7 blog is finally starting to integrate the operating system into their articles. Most of the previous articles that have been posted at the website were about theoretical aspects and things Microsoft learned from past operating systems.

The first thing that might catch the attention is the Color Hot-track feature. This is a visual aid that becomes active when the user moves the mouse over a Taskbar icon.
When a person moves her mouse over a running program on the taskbar, she will be pleasantly surprised to find that a light source tracks her mouse and the color of the light is actually based on the icon itself. We calculate the most dominant RGB of the icon and dynamically paint the button with this color.

Overlay Icons and Progress Bars have not been mentioned before as well:
Cleaning the Notification Area warrants us to consider other ways that programs can surface important information. We’ll always had overlay icons throughout Windows (e.g. to show shortcuts in Explorer) so we decided to bring this functionality to the taskbar. An icon can now be shown over a program’s taskbar button. Furthermore, programs can also give feedback about progress by having their taskbar button turn into a progress bar.
