The greatest windows tips of all time

Toggle between apps: Use Alt-Tab to switch open programs without touching your mouse. The oldest--and still the best--Windows timesaver.
Navigate app windows: Press Ctrl-Tab to cycle through an application's windows (or through a Web browser's tabs). First cousin of the tip above, and probably the most underrated tip ever.
When in doubt, type it out: If you don't want to hunt through nested menus and the like, you can access most functions, applets, or files the old-fashioned way--by entering them into the Search box. Type Calculator, Control Panel, or even the name of a piece of music on your hard drive, and press Enter.

Proxy - Surf the web anonymously!!!

In computer networks, a proxy server is a server (a computer system or an application) that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource available from a different server. The proxy server evaluates the request as a way to simplify and control their complexity. Today, most proxies are web proxies, facilitating access to content on the World Wide Web.
