Turn off visual effects
If Windows
is running slowly, you can speed it up by disabling some of its visual
effects. It comes down to appearance versus performance. Would you
rather have Windows run faster or
look prettier? If your PC is fast enough, you don't have to make this
tradeoff, but if your computer is just barely powerful enough for Windows 7, 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 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:

Open Performance Information and Tools by clicking the Start button , and then clicking Control Panel. In the search box, type Performance Information and Tools, and then, in the list of results, click Performance Information and Tools.

Click Adjust visual effects.  If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

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.)
