Microsoft Windows 7 OS

What if a new version of Windows didn't try to dazzle you? What if, instead, it tried to disappear except when you needed it? Such an operating system would dispense with glitzy effects in favour of low-key, useful new features. Rather than pelting you with alerts, warnings, and requests, it would try to stay out of your face. And if any bundled applications weren't essential, it would dump 'em.

It's not a what-if scenario. Windows 7, set to arrive on new PCs and as a shrinkwrapped upgrade on 22 October, has a minimalist feel and attempts to fix an­­noyances old and new. In contrast, Windows Vista offered a flashy new interface, but its poor performance, compatibility gotchas, and lack of compelling features made some folks regret upgrading and others refuse to leave Windows XP.

Windows 7 is hardly flawless. Some features feel unfinished; others won't realise their potential without heavy lifting by third parties. And some long standing annoyances remain intact. But overall, the final shipping version we test drove appears to be the worthy successor to Windows XP that Vista never was.

Windows 7 Interface: The New Taskmaster

The Windows experience occurs mainly in its Taskbar - especially in the Start menu and System Tray. Vista gave the Start menu a welcome redesign, in Windows 7, the Taskbar and the System Tray get a thorough makeover.

The new Taskbar replaces the old small icons and text labels for running apps with larger, unlabeled icons. If you can keep the icons straight, the new design painlessly reduces Taskbar clutter. If you don't like it, you can shrink the icons and/or bring the labels back.

In the past, you could get one click access to programs by dragging their icons to the Quick Launch toolbar. Windows 7 eliminates Quick Launch and folds its capabilities into the Taskbar. Drag an app's icon from the Start menu or desktop to the Taskbar, and Windows will pin it there, so you can launch the program without rummaging around in the Start menu. You can also organise icons in the Taskbar by moving them to new positions.

To indicate that a particular application on the Taskbar is running, Windows draws a subtle box around its icon - so subtle, in fact, that figuring out whether the app is running can take a moment, especially if its icon sits between two icons for running apps.

In Windows Vista, hovering the mouse pointer over an application's Taskbar icon produces a thumbnail window view known as a Live Preview. But when you have multiple windows open, you see only one preview at a time. Windows 7's version of this feature is slicker and more efficient. Hover the pointer on an icon, and thumbnails of the app's windows glide into position above the Taskbar, so you can quickly find the one you're looking for. (The process would be even simpler if the thumbnails were larger and easier to decipher.)

Also new in Windows 7's Taskbar is a feature called Jump Lists. These menus resemble the context sensitive ones you get when you right click within various Windows applications, except that you don't have to be inside an app to use them. Internet Explorer 8's Jump List, for example, lets you open the browser and load a fresh tab, initiate an InPrivate stealth browsing session, or go directly to any of eight frequently visited web pages. Non-Microsoft apps can offer Jump Lists, too, if their developers follow the guidelines for creating them.

Other Windows 7 interface adjustments are minor, yet so sensible that you may wonder why Windows didn't include them all along. Shove a window into the left or right edge of the screen and it'll expand to fill half of your desktop. Nudge another into the opposite edge of the screen, and it'll expand to occupy the other half. That makes comparing two windows' contents easy. If you nudge a window into the top of the screen, it will maximise to occupy all of the display's real estate.

The extreme right edge of the Taskbar now sports a sort of nub. Hover over it, and open windows become transparent, revealing the desktop below. (Microsoft calls this feature Aero Peek.) Click the nub, and the windows scoot out of the way, giving you access to documents or apps that reside on the desktop and duplicating the Show Desktop feature that Quick Launch used to offer.

Getting at your desktop may soon become even more important than it was in the past. That's because Windows 7 does away with the Sidebar, the portion of screen space that Windows Vista reserved for Gadgets such as a photo viewer and a weather applet. Instead of occupying the Sidebar, Gadgets now sit directly on the desktop, where they don't compete with other apps for precious screen real estate.

Old Tray, New Tricks:

Windows 7's Taskbar and window management tweaks are nice. But its changes to the System Tray - aka the Notification Area - have a huge positive effect.

In the past, no feature of Windows packed more frustration per square inch than the System Tray. It quickly grew dense with applets that users did not want in the first place, and many of the uninvited guests employed word balloons and other intrusive methods to alert users to uninteresting facts at inopportune moments. At their worst, System Tray applets behaved like belligerent squatters, and Windows did little to put users back in charge.

In Windows 7, applets can't pester you unbidden because software installers can't dump them into the System Tray. Instead, applets land in a holding pen that appears only when you click it, a much-improved version of the overflow area used in previous incarnations of the Tray. App­lets in the pen can't float word balloons at you unless you permit them to do so. It's a cinch to drag them into the System Tray or out of it again, so you enjoy complete control over which applets reside there.

More good news:

Windows 7 largely dispenses with the onslaught of word balloon warnings from the OS about troubleshooting issues, potential security problems, and the like. A new area called Action Center - a revamped version of Vista's Security Center - queues up such alerts so you can deal with them at your convenience. Action Center does issue notifications of its own from the System Tray, but you can shut these off if you don't want them pestering you.

All of this helps make Windows 7 the least distracting, least intrusive Microsoft OS in a very long time. It's a giant step forward from the days when Windows thought nothing of interrupting your work to inform you that it had de­­tected unused icons on your desktop.
