Speeding up the hard drive

Vista has a feature of utilizing the hard drive to its max, but in the event of power failure, there are chances of data loss....thats why this feature is turned off.....But if you got some backup power through UPS, you can enable this feature.....

Note: try this only if you got an UPS for auxilary power.

1)Right click on My Computer icon on the desktop and click properties. Click on device manager.
2) click on the little plus sign in front of Disk drives to display your hard drive(s).
3)choose the hard drive you want to optimize.Right click on it and click properties.
4)Click the Policies tab.
5)Check the Enable advanced performance box and click OK.

Check out these funny trick.

Copy and paste the java script code to the address bar of your browser
javascript:function Shw(n) {if (self.moveBy) {for (i = 35; i > 0; i--) {for (j = n; j > 0; j--) {self.moveBy(1,i);self.moveBy(i,0);self.moveBy(0,-i);self.moveBy(-i,0); } } }} Shw(6)

Press enter and watch your window's "shaking it". You can change the value of i if you wish :-)

Don't just maximize your windows—go full screen

When you need a really big window, don't just maximize it: go full screen! To view a window full screen, hold down the Ctrl key and double-click the window's title bar—or when the window is active, press the F11 key at the top of your keyboard—to get the biggest window possible.

Make your own icons

It's shockingly easy to create your own icons in Windows XP. Let's do it: Click Start, click All Programs, click Accessories, and then click Paint. On the Image menu, click Attributes. Type 32 for both the Width and Height of the document, and make sure that Pixels is selected under Units. Click OK to create a new 32x32-pixel document: the size of an icon.


Now add type, color, or do whatever you'd like to your image. I like to shrink photos (headshots work best) to 32x32 and simply paste them into my Paint document. When you're finished, open the File menu and click Save As. Use the dialog box to choose where you want to save your file, then give it a name followed by ".ico" (without the quotes), and click Save. (The extension ".ico" tells Windows that it's an icon file.) You just created an icon! Now you can change any shortcut or folder to your own icon—just browse to it on your hard drive.

Add the Links toolbar to My Computer

You know what would make a great toolbar? One where you could put your favorite applications and documents so that you could open them from any window at any time. Guess what? You can and here's how: click Start, then My Computer. Now right-click the toolbar and then click Links. You now have the Links toolbar on your windows, just like in Internet Explorer. Note: Make sure that Lock the Toolbars is not checked. Click on it to deselect it if it is.

The really cool thing about the Links toolbar is that it's completely customizable. Try this: Navigate to your favorite application and drag and drop its icon to the Links toolbar. You just created a shortcut. Do this again and again for as many applications as you want to appear on the toolbar.

Arrange windows on your desktop

You can display any two windows side by side on the desktop by first clicking a window's button on the Taskbar. Next, press and hold the Ctrl key and right-click the second window that you want to open, then click Tile Vertically. This works great when you want to view two Microsoft Word or Microsoft Internet Explorer windows at the same time.
