The Windows registry is just a collection of configuration files that are responsible for the correct operation of the entire system. Its damage or deletion of key entries may result in data loss or complete computer immobilization. Is it worth to clean up this registry periodically? If so, which program should I use?
Why clean the Windows registry?
Honestly, I’m not a fan of cleaning the registry, because it can do more harm than good, especially if we do not really know what we’re doing. As long as the computer is working properly, it usually does not make sense to move anything. Tricks with the registry were popular 20 years ago at the time of Windows 98, when actually entries there emerged could cause problems or were incorrectly removed when uninstalling an application. In Windows NT 4.0 and above systems, there were no problems, and in Windows 10 it seems to me that it does not exist anymore.
For example, let me use my Windows 10, which is an update from Windows 7, which was installed good 8 years ago. According to a popular tool – CCleaner, which I used to scan the registry, 199 problems were detected. 199 for a few or even several thousand entries that were created there at the turn of these few years. Most of them are not harmful, and even not a problem, such as information about incorrect file extensions. Cleaning this list does not make sense, but the application is not useless at all, because it has a different, much more important module.
Cleaning temporary files in Windows
The main function of CCleaner has always been to clean Windows and applications installed in it from temporary files. Especially when using web browsers, a lot of small files are kept in temporary directories, in order to speed up the loading of websites. In times of modem connections and websites created with simple HTML, it made a lot of sense, today I have the impression that this is not so important.
However, browsers and other applications keep files in their directories that they will probably never use, so it should be removed from time to time. Windows 10 has its own tool of this type – Disk Cleanup, which however focuses mainly on system files related to, for example, updates. These can also collect quite a lot, especially if you’re after a large update that changes the version number. However, it is worth bearing in mind that deleting these files deprives you of the possibility to return to the previous version of the system. However, if the system is stable, it may be worth recovering even a few GB of space on the system partition.
For the most part, because I’m far from saying that it’s best to delete them all. As far as the cache does not constitute any added value, the browsing history or especially cookies (popular cookies) may still be useful for you. If you clean everything as it flies, then it will turn out that your browser has suddenly forgotten the login and password for many websites and you must be logged in again. By the way, advertisements displayed on websites will no longer be matched ;-). In CCleaner’s options, you can view the list of cookies found and add them to the white list, which will protect them from deletion in the future. After selecting the data you want to get rid of, cleaning takes a few seconds to several minutes.
By the way, one more note, CCleaner is a nice tool created by a small company Piriform. However, some time ago it was taken over by Avast and now during installation by default the option to install an antivirus program with the same name is selected. Remember to uncheck this option before clicking “Install”.
