You buy a shiny, brand-new PC. You expect it to be clean, lean, and mean. Wrong! Buy any new PC, and you'll find it full of "craplets"--software installed for no reason other than that the PC maker gets paid to put it there. These craplets slow down your PC startup and its general operation. Dell is particularly notorious for filling new PCs with craplets.
The free PC DeCrapifier removes dozens of craplets automatically. Using this program is exceedingly simple. Just run it, and it does its removal work automatically. Don't expect it to completely clean your PC, because it removes only a specific set of craplets and trialware programs, those that are specifically put on new PCs, such as QuickBooks Trial, Wild Tangent Games, Dell URL Assistant, and many others.
