Slow Running computers are one of today's most commonly encountered problems
Many new systems come already supplied with “Crapware” installed, almost all of which is not necessary for the successful running of the computer. All it does is slow down startup times and lead to slow running machines.
Over time systems start to run slower and slower, this is usually happens whilst installing software, many common software solutions install hidden applications and un-needed extras.
Some applications will try to install new browsers, and change the browser start up page.
Default installation of everyday applications can lead to added extras being installed unless they are specifically un-selected during the installation process
