Slow computers are incredibly annoying and frustrating, preventing you from doing even the most simple tasks on your PC. A slow computer makes it difficult for you to play games, watch movies and even do your work, but luckily, there's a simple way to speed it up that even a beginner can do.

The problem of a slow PC is huge – with millions of people having to put up with them every day. However, instead of buying some expensive upgrades, there's actually a simpler way to make your computer speed up. It's all to do with a little-known part of Windows called the 'registry'. This is the central database for Windows which stores all the settings and options for your computer, making it one of the most important and well-used parts of your system.

Unfortunately, it also causes your computer to run slow and is actually believed to be the largest cause of a slow computer. The problem is that since Windows is constantly using the registry to tell it how to do everything from boot up to log you in, it has 100's of registry files open each time you use your PC. The problem is that Windows actually gets confused and ends up saving many registry files in the wrong way, which makes them extremely difficult to read, making Windows actually slow down as it tries to decipher these problematic files.

With many computers having 1,000's damaged files in the registry, it's no wonder that it's one of the biggest causes of a slow PC. But remarkably, it's one of the easiest to fix. Basically, you just need to use a tool called a 'registry cleaner' to go through each registry file in the registry database, and fix any of the damaged ones that it finds. This allows it to quickly fix all the problems in your computer, allowing it to easily open the files it needs.
