Worse, the Registry, which is a database of information about your computer, is left with erroneous entries that point to long-deleted directories, link filetypes to applications that don’t exist and even attempt to launch startup applications that were removed from your machine. They all rely on the same element and that’s the operating system and installed applications.Īfter installing and removing software, then browsing the Internet for a few months, all sorts of temporary information is left strewn across your hard drive. There’s little difference between a 1-year-old PC and a brand number computer. Result? You settle in to your old habits of installing and testing software, removing them from your system and quickly misunderstanding that it’s the software that drives your computer, not the hardware. Your first thoughts will be that you were right to sell your old PC as this one is so much more speedy that you have become more productive.

Go out and buy a new computer, turn it on for the first time and you’ll be amazed how quickly it boots and launches the installed applications.
