Microsoft Windows Vista review

After five years and a budget reckoned to have neared $10 billion, Windows Vista is here. It's promised to be many things along the way - some of it's made it through to the final product, some has fallen by the wayside. But the code is now locked down and we're finally left with the successor to XP.

We've been using the Vista beta code for more than two years, much of that on machines we use every day. Over the next seven pages, we reveal what's good, bad and what still has to prove itself.

The compatibility question

Despite some of the hysteria surrounding Vista's hardware requirements, if your PC runs Windows XP without problems, it's almost certain to run Vista without issue too. Even Aero's visual effects aren't particularly demanding - the integrated graphics of a modern entry-level notebook (Intel's GMA 950 or more recent) will cope. The one caveat to this is RAM - while XP may scrape by on 512MB or less, Vista benefits hugely from 1GB or more.

Other good news is that there are significantly more drivers packaged with Vista than in XP, as well as many more on Windows Update (you can check this before you install). If you own a PC from the past two years with nothing outlandish in the way of hardware, you can reasonably expect a fully populated Device Manager. Most networking hardware works immediately and we've yet to find a USB printer that won't work.

Beyond that, it's currently a mixed bag. The default Nvidia and ATi drivers have exhibited bugs, integrated Realtek sound chips and many of Creative's discrete cards are incorrectly handled, and some common RAID controllers still don't have Vista drivers. We expect another round of releases in late January, and we'd advise checking for new drivers on a weekly basis for the time being.

When it comes to software compatibility, the biggest problem comes from installers that simply don't recognise the operating system and stop. The compatibility mode (similar to that in Windows XP) sometimes helps but it isn't guaranteed - again, check with manufacturers, since many installers already have patches. Other problem areas include hardware-specific applications (such as notebook hotkey utilities), disc-burning software (including Roxio and Nero's latest versions), and those that sulk over the Aero graphics engine (such as iTunes). With some of these, Vista will switch off Aero globally, re-enabling it once the application is closed.

The other big issue is security software, as most existing applications won't work with Vista's new security model - particularly in the x64 versions. If you feel uncomfortable without anti-virus software installed, upgrade to the latest version first.

The Aero experience

All the versions of Vista you're likely to come across, except Home Basic, will support Aero. This is Microsoft's name for Vista's "next-generation desktop experience", the most obvious sign of which is the Windows Aero theme: this offers transparent windows, dynamic reflections and sophisticated animations. According to Microsoft, this makes it easier to focus on the active window, but we haven't noticed a dramatic increase in our productivity as a result. It looks nicer, though.

Just to confuse things, the "Aero experience" isn't simply the Aero Glass theme - Aero also enables live taskbar previews (so you see a "live" preview of the minimised program when you hover the cursor over the taskbar) and niceties such as Windows Flip and Flip 3D. Flip is the evolution of the old and trusty Alt + Tab, but with live previews instead of the icons in XP. Flip 3D takes things one stage further by stacking the Windows obliquely in a pseudo-3D environment.
