Your computer's registry plays a highly important factor in maintaining the efficiency of your machine. It shows and records all the processes that you do on your computer, including those that you have no direct influence over or that you do not initiate yourself. While most processes are automatically deleted after some time, there are also those that are not removed unless you do it yourself or you use a separate computer program for. The PC registry is such an active system, as it registers, as the name itself suggests, your every movement: from opening a new spreadsheet to launching your web browser. Needless to say, your every movement is recorded on this software.

As time goes by, as you use your computer day in and day out, the PC registry gets filled up with processes that it has to remember and maintain in the background. It does not actually get filled as if it has a limitation, but just like anything that has too many tasks in its hands, the PC registry can also become overwhelmed with the sheer number of continuous operations of your software programs. One pressing factor would be the uninstalling of applications because often, some traces of the original installation are left behind. When this continuous and more applications are uninstalled, the PC registry can get confused with all the unessential elements still lying around. In short, it does not know what to do with these useless files. In this process, it can cause some errors, both minor and major, which will eventually cause your computer to freeze.

To avoid encountering such problems, it is best that you employ a reliable registry cleaner on a regular basis. The frequency that you clean your registry depends on your level of computer usage. It is always safer to use a registry cleaner than doing everything by yourself. Unless you are a professional, you can risk crashing your computer when you do it on your own.
