First of all in order to know what whether or not you need a registry clean you have to know what kind of registry I am talking about. You also have to know what that particular kind of registry does, and what kinds of things happen when your registry is “dirty.” In the next several paragraphs I want to tell you about each of these things and in so doing hopefully answer the title question.
The type of registry that I am referring to is the registry that is used by all windows operating systems. So if you have a computer that runs with windows (which 95% of America does) than you need to read this article. The registry is used by windows to store all of the settings that are used in any bit of software that is ever run on your computer, and holds it whether or not that software is still on your computer (this is where you may start to see what a registry clean is all about). Anyway, settings may be the user preferences for simple things like colors and layouts, or more complicated settings for speeds, or orders of operation, or schedules of important events, OR less complicated but very much more important things like usernames and passwords that link to often very important and very private information. Settings also may include those for software that is used by web pages linked to temporary internet files (and this is where the huge amount of useless information is contained).
Just as an aside the registry because it contains, as we have talked about above, some rather important information that should be protected you should also have in mind that the typical software package that you buy to do your registry clean often has another component that finds code uploaded onto your computer by the different malware programs that are running rampages on the internet right now like spyware and adware. It “cleans” this off and also protects your pc from future intrusions.
Anyway, the information on this registry obviously builds over time. More and more information is added, some useful and some that is useless. When the registry starts to near capacity the computer may do several things that are very annoying to the user. These include slow operation, freezing, spontaneous and unwanted shutdowns, and so on. So in conclusion before you go an buy another computer try a registry clean you will be surprised how much it helps.
