PCWorld - It's officially spring, so why is your computer still moving like it's half frozen? After all those long winter nights surfing shady sites, it's no wonder. Here's how to give your most important devices a spring cleaning fit for a May Queen.
Clean It OutThe first thing you'll want to do is clear out the riff-raff—unused programs and browser extensions, obsolete registry entries, and expired permissions. Uninstall unused and under-utilized programs on your desktop and laptop systems, clear out forgotten apps from your mobile devices (Sorry, Angry Birds Rio). Give your registry a scrubbing with CC Cleaner, a free program for both Windows and Mac, that will clear old registry entries (for PCs) as well as empty recycle bins, zero out recent document lists, and erase a variety of browser information—Temporary files, history, cookies, download history, form history—from the major browsers.
Also be sure to take a look through your browser's extensions list and remove any rarely used features. The same goes for Google users: Go to your Google account's security screen, select the "Connected applications and sites" option from the bottom of the list, and nix any old devices that you no longer own or operate.
