One of the reason for the Vista get famous is because of it's virtual effects. But it is also, sometimes become a disadvantage to the users when they are using a very limited resources in the machine. If your Vista is running slowly, then you can speed it up by disabling some of its visual effects. It comes down to appearance versus performance. Its your choose, to have a faster working vista or having a pretty good look. Would you rather have Vista run faster or look prettier? If your PC is fast enough, you don’t have to make this trade off, but if your computer is just barely powerful enough for Windows Vista, it can be useful to scale back on the visual bells and whistles. You can choose which visual effects to turn off, one by one, or you can let Windows choose a bunch for you. There are 20 visual effects you can control, such as the transparent glass look, the way menus open or close, and whether shadows are displayed. To adjust all visual effects for best performance: 1. Open Performance Information and Tools by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clicking Performance Information and Tools. 2. Click Adjust visual effects . If you are prompted for an administrator password or confirmation, type the password or provide confirmation. 3. Click the Visual Effects tab, click Adjust for best performance , and then click OK . (For a less drastic option, select Let Windows choose what’s best for my computer .)
