Moving to Microsoft's Windows Vista is becoming a necessity rather than an option. The operating system is already delivered standard on most new PCs, and Vista solves enough problems with older versions of Windows that it is tempting holdouts as well.
But the move to Vista can be fraught with frustration. One frequent complaint among new users is that Vista seems slower under some circumstances than their previous operating system.
The good news is there are steps almost everyone can take with their current system to make sure Vista is running as fast as it can.
Tune your display
Vista's Aero interface is responsible for much of the perceived slowness of the operating system. It's true that you need a beefier graphics card to run Aero adequately - cards with 256MB of video RAM are recommended. But even with a fast card, Aero can seem pokey. .
You don't have to dump Vista to get the snappiness back, though. First, turn off Aero's transparency. To do so, right-click the desktop, select Personalize from the pop-up menu, and then click Windows Color and Appearance. Uncheck the box labelled "enable transparency." Click OK.
Another option is to get rid of Aero's transparency and many of its other resource-intensive features by simply using a theme that looks more like a previous version of Windows. To do this, you simply choose a non-Aero theme.
Right-click a blank space on the Vista desktop, and select Personalize from the pop-up menu. In the Personalize dialog, select Windows Color and Appearance. Click Open Classic Appearance Properties. Now choose a theme in the Color Scheme list box. You'll have choices such as Windows Classic, Windows Vista Basic, or Windows Standard theme.
You might also want to ditch the Vista sidebar. While it's a nifty feature, many folks have already replicated the functionality of the sidebar's applets with various taskbar utilities. And the applets in the Vista sidebar can be resource intensive and slow down screen redraws.
To remove the Sidebar, right-click it, select Properties from the pop-up menu, and then uncheck "Start Sidebar when Windows starts." Click OK. Then right-click the Sidebar and click Close Sidebar. If you ever want it back, just open the Start orb, type "sidebar" in the search field, and press Enter.
Turn off indexing
Vista constantly indexes the contents of your hard drive. The reason: search fields are ubiquitous in the operating system - everywhere from the Start menu to Explorer windows. But on some machines, all that indexing can take a serious toll on performance.
You can turn off automatic indexing altogether and get back the processor cycles that otherwise would be devoted to it. To turn off indexing, click the Start orb, and then Computer. Right click the C drive.
On the General tab of the resulting dialog box, remove the check mark next to "Index this drive for faster searching," and click OK. On the subsequent dialog box, select "Include subfolders and files."
Turn off UAC
Vista's user account control (UAC) is one facet of the operating system's beefed-up defense against malicious software. Unfortunately, UAC prompts users incessantly with dialog boxes.
The result is that many things seem to take longer - and in fact they do, as you're required to perform more steps to complete tasks that were quicker in XP.
