PC Decrapifier removes unneeded programs from brand-new and used PCs. It takes you step by step, giving recommendations on what to ditch. Software downloads often come with other add-ons or in bundles. But it's not only what you've download that can be a burden on your system - new PCs come with pre-installed software that you might never even use. Most of them are harmless but if you have more than just few they just could slow down your machine.
