Booting up a brand-new PC is always fun. It runs fast, everything is snappy and highly-responsive. You started to get more productive, get more work done and have fun doing it. However, after a few months, it stops booting quickly and every application is taking way too long to load. Your system starts behaving stubbornly and doesn’t respond well to your commands. Relatable? That’s the whole premise on which the ‘PC Cleaning’ tools industry is based. But before getting deep into the ocean, let’s see why computers actually get slow with time and why taking the help of a PC Cleaner Software is indispensable. Some PC optimization tools even try to hype up small even non-existent issues. Their intention is to make the user, who isn’t much tech-savvy, panic and end up paying for the software. But my personal experience with a couple of free computer clean up tools hasn’t been that bad. I remember getting a significant improvement in my old PC’s boot time after I cleared the junk data using CCleaner. Still, I won’t recommend using any random cleaning tool to fix your PC. In fact, as it’s said if it ain’t broke, don’t fix it. Anyway, here some of the best computer cleaners that you can try if you seriously feel the need to use them on your machine.
