1. Don't just maximize your windows—go full screen
When you need a really big window for viewing photos and videos, don't just maximize it: go full screen! This tip works great for viewing photos and videos at maximum size in Windows Explorer or Windows Media Player, utilizing screen space usually occupied by the header at the top of the screen and the taskbar at the bottom. Here’s how:
Open any photo in Windows Explorer, or open a photo or video clip in Windows Media Player. Do one of the following:
In Windows 7 and Windows XP, click the F11 key at the top of your keyboard.
to undue full-screen mode and restore the window to its normal view, press the Esc (Escape) key at the top of your keyboard


2. Customize the Navigation pane
You can use the navigation pane (the left pane) to find files and folders and display links to frequently used folders and other items. You can also move or copy items to a destination in the navigation pane.
If you don't see the navigation pane on the left side of an open folder window, click Organize, point to Layout, and then click Navigation pane to display it.
To customize the navigation pane in Windows 7
In an open folder or library window, click Organize, and then click Folder and search options.
In the Folder Options dialog box, click the General tab, and then do one or both of the following:
To show all the folders on your computer in the navigation pane, including your personal folder, select the Show all folders check box, click Apply to see the change, and then click OK.
To automatically expand the navigation pane to the folder that's selected in the folder window, select the Automatically expand to current folder check box, and then click OK.
