PC Pro investigated which PC makers preinstall the most crapware on their laptops and what kind of impact these programs have on the performance of your system, you can read the report over here. The site concludes Acer, Sony and HP are the worst offenders and shows it's definitely worth it to clean up this crapware as the preinstalled software wastes valuable resources and can increase boot times by as much as 2 minutes.
You wouldn’t buy a new car that took five minutes to get out of first gear or a new hard disk that was already half-full of files – but plenty of people are unwittingly buying a laptop that’s been hobbled before it’s even left the factory.
That’s because crapware – the common term for “free” software that’s piled on to new PCs – can have a catastrophic effect on boot times, performance and hard disk space.
To find out which PC companies are the worst offenders, we put nine machines from the major manufacturers through a battery of tests designed to highlight where they’re being run ragged by unwanted software.
