Did you know that while Windows is runningis there an every second appeal to the registry? It reads existing keys and writes new ones. This is a vital necessity for operating the OS, because the registry stores critical data. With intensive use of a PC, which means installing new programs, and then deleting them, the registry becomes clogged with unnecessary keys and partitions. And all this is then loaded into the RAM, taking away precious resources.

But there is a whole family of programs capable ofsupport the software part of your PC in the "form". The most useful of them are registry cleaner and defragmenter. If the first simply removes the irrelevant keys and partitions, the second one orders the registry files on the hard disk for convenient access to them, slightly speeding up the system. Let's see what useful programs this direction the Internet can offer us. For convenience, we will only talk about free programs, you will not have to pay for one of the listed ones.

It should also be noted that the effect of suchoptimizations is relatively small. Therefore, the program should be chosen based on personal preferences regarding the aesthetic appeal of the interface. So, let's get started.

1. Ccleaner. Helps to remove unnecessary keys and temporary files. Among them - temporary Internet files, a basket, autocomplete forms, cookies, hidden files index.dat. In addition, Ccleaner is able to work with cleaning of garbage files of non-standard programs - Opera, Firefox, Winzip and so on. It is possible to create a backup copy. The program is suitable as a registry cleaner for Windows 7, the "eight" is also supported, like all previous versions of the OS.

2. Wise Registry Cleaner Free. Another automated registry cleaner. Features - full security of all operations due to backup, quick return to the previous edition of the registry. It is designed to work with Windows Vista, Seven and old good XP.

3. Vit Registry Fix. A whole package of programs from a talented Ukrainian programmer. Deletes not only incorrect registry keys, but also unnecessary files. In addition, it provides for managing startup and the availability of the application manager (unlike the regular one, carefully removing unnecessary registry keys during the deletion).

4. Glary Utilities. Also a handy set of software to optimize system performance. The main advantage is fixing the main problems with the registry, shortcuts, suspicious programs in the autorun, spyware in just one click of the left mouse button. It's more correct to say that there are two, because the changes in the registry have to be confirmed. In addition to the main module, there is an auto-optimization of RAM, a security manager and a module for deleting "junk" files.

5. Auslogics Software Pty Ltd. This registry cleaner is characterized by increased work speed. Convenience lies in the now classic three-step system. Just press a couple of times "next" - and ready. Even with all the minimum functions, backup is provided. It is recommended for those who need a utility to optimize the registry for "cleaning their conscience", say, to service engineers, but not interested in optimizing Windows and any tweakers.

6. PowerTools Lite. This program we could not ignore. After all, this is a free version of jv16 PowerTools, a truly legendary utility from Macecraft Software. According to the results of the reviews, this program is the best registry cleaner. The light version differs in its extreme simplicity and sharpness for cleaning the registry and obsolete MRU records. In simple mode, the program simply finds and corrects errors (choose oneself), and the extended mode differs in the ability to select the system's security relation to the number of errors found. Therefore, the more errors you want to correct, the higher the risk of a subsequent system inoperability, so be extremely careful.
