What does registry optimization mean? What is registry optimization and why is it needed? Cleaning out the Prefetch folder for faster loading

Good time everyone!

The system registry in Windows is a large database that stores settings and settings for applications, user profiles, presets, etc. (although in my opinion, today, the registry is a whole bag of “crutches”, which is more needed for compatibility with old software. But that’s not what we’re talking about...)

As with any database, over time (if it is not cleaned), a large amount of “garbage” data accumulates in it: settings of programs that have been deleted long ago, erroneous information, “empty” lines, etc. All this can affect the performance of Windows. What’s interesting: Windows itself does not provide a tool for optimizing the registry (a little surprising).

Below I will show several utilities that will help you “clean up” these Augean stables and make Windows more responsive. I think this will not hurt many people!

Let's get down to business...

Note: by the way, you might find this article useful on how to enter the system registry (even if it has been blocked) -

Registry optimization

Method No. 1

An excellent multifunctional utility for tidying up the entire system as a whole (and the system registry in particular). In my humble opinion, one of the best of its kind.

It has a convenient express check of the system, which will immediately display the number of problems and offer to solve them. Please note that the utility is free!

Peculiarities:

1. cleaning the registry: removing erroneous lines, old “tails” from games and software;
2. defragmentation and compression of the registry;
3. the ability to edit the registry manually (important! only for experienced users);
4. there is a Windows startup editor;
5. removing "junk" files from Windows: temporary files, shortcuts, empty directories, etc.;
6. there is a built-in uninstaller: it will even remove software that you cannot “get rid of” using conventional methods;
7. Supported by all popular OS Windows 7, 8, 10 (32/64 bits).

Method No. 2

This program captivates with its “simplicity” and effectiveness. After installing and launching it, you will see a window with only three tabs: cleaning, optimization, compression (there is also help, but I don’t count it). To put the registry in order: you need to press only 2 buttons - first “Analysis” (see what the utility finds), and second “Optimization”. Simple, clear, concise!

Wise Registry Cleaner - registry optimization section / Clickable

By the way, I would like to note that Wise Registry Cleaner makes a copy of the registry before any of its actions (just in case, a backup never hurts).

I would also highlight the function of compressing the system registry and defragmenting it. After such complex optimization, you often directly “feel” how Windows began to work a little more lively...

Among the advantages: there is an automatic mode. In it, the utility will launch at the designated time, clean and optimize your system. It is very convenient in cases where you regularly work on a PC, but forget to launch the “cleaner” on time...

Overall, Wise Registry Cleaner leaves a very pleasant impression. I recommend having a shortcut to this program on your desktop and cleaning up the “shortcomings” of Windows from time to time.

Note: the utility is free, supports Russian, relevant for Windows 7, 8, 10 (32/64 bits). In terms of cleaning efficiency, it is one of the best in its segment.

Since you are interested in registry optimization, I can’t help but recommend instructions for optimizing Windows 10 OS -. The material in the article will help increase the performance of your system (in some cases, significantly!), reduce the number of errors, lags and freezes.

I have everything on the topic of the question, additions (as always) are welcome...

Good luck!

The registry is the foundation of the operating system, storing information necessary to configure the operating system to work with users, programs and devices. As you work, entries appear in the registry about newly installed programs, devices, and settings. Information about deleted programs is also saved here, if the uninstallation was carried out incorrectly, or the uninstallation procedure did not completely remove the parameters specified during installation, links to deleted files are saved, and so on. Over time, more and more garbage appears in the registry. It is not surprising that the size of the registry is constantly increasing over time.

The registry of operating systems Windows XP and earlier versions, in which a lot of garbage accumulates, begins to generate system errors more often, even stopping the system. In modern versions of Windows 7-10, large amounts of data in the registry do not entail any negative effect on system performance.

To prevent errors in Windows XP, you need to regularly clean the registry or optimize it. The optimization process is carried out in several stages. The first step is to compress the registry. Compression is the final removal of unnecessary and marked for deletion entries, which leads to a reduction in the overall size of registry files, because when removing unnecessary entries from the system registry, they are only marked as deleted, although in fact they are still present and taking up space.

But the optimization work doesn’t end there. Even permanent deletion of unnecessary entries does not automatically change the disk space occupied by registry files. Therefore, it is recommended that after cleaning the registry, in addition to optimization, you also defragment the system registry.

Why is defragmentation needed?

When you install an operating system on a new disk, files are written to sequential clusters. But after some time, after installing and deleting applications and individual files, “gaps” begin to appear in the previously filled sequence of clusters. And new files, in the absence of the required free space, begin to be recorded “in a split manner.” In the process of reading a defragmented file, the disk head has to travel a long path from one fragment to another each time, and this path can be long. As a result, the computer slows down.

Defragmentation is the process of combining several parts of one file into a single fragment. This is the second stage of registry optimization. During the defragmentation process, the fragments of files scattered across the hard drive are organized: clusters are organized in such a way that individual pieces of files are located sequentially, one after another, if possible. In addition, all data is moved to the beginning of the hard drive, and free space is located at the end. As a result, the speed of accessing the registry and, accordingly, the performance of your computer increases.

In modern versions of the Windows 8-10 operating system, the defragmentation process is performed automatically during idle time. During this process, the system registry files are also defragmented.

It is believed that, like defragmenting a disk, optimizing the registry can help speed up PC performance.

Back in the early 2000s, the Windows registry was one of the biggest performance bottlenecks. Hard drives and processors were slow, and the registry itself was poorly optimized, forcing the operating system to search for the correct registry key with some delays, which overall slowed down the PC. Nowadays, modern PCs are already so fast that cleaning the registry will help improve PC performance very little.

And yet, many experienced users still recommend registry cleaners.

If you have a slow hard drive, then registry optimization can help. Although most likely making your system “feel better” is similar to the placebo effect. But if you believe in the power of cleaning the registry, then I recommend sticking to the following list of applications that have proven themselves among experienced users.

Comodo PC TuneUp is not just a registry cleaning application. This is a universal configuration utility that includes, among other things, the function of working with the registry. Please note that fixing the registry is different from cleaning the registry, and this is why Comodo PC TuneUp is more secure than its competitors.

This tool finds and tries to fix serious registry problems.

In fact, most registry problems, at least from Vista onwards, are generally harmless. But if you really want to comb through your registry and find faults in it, then Comodo PC TuneUp is best suited for this. Not to mention, this tool is developed by Comodo, a company specializing in cybersecurity and computer security. They have a solid track record and I find them more reliable than most other developers.

JetClean is a great all-in-one tool but provides a lightweight approach. The app is not bloated with unnecessary features like most PC optimization tools, which is why JetClean is effective.

In addition to cleaning the registry, JetClean has four other built-in cleaning features: System Cleaner (operating system files), Application Cleaner (installed junk files), Shortcut Cleaner (invalid shortcuts to files and START menu items), and RAM Cleaner (for leaks). memory).

Other useful features include system startup optimization, Internet connection speedup, computer performance booster, and the ability to create a portable version that you can carry with you on a USB drive.

Wise Registry Cleaner is a 2-in-1 application that cleans the registry and tunes system performance. The application performs its tasks quickly and efficiently.

When it comes to the number of registry errors, Wise Registry Cleaner is slightly worse than JetClean, in my humble opinion. The simplicity of the interface will appeal to everyone, plus an additional bonus is the inclusion of a registry defragmenter in the utility. If your main problem is PC performance, then System Tuneup can help.

You have the option to upgrade to the Pro version for $20 plus $15 per year as a subscription fee. The Pro version adds multi-user cleaning, automatic scheduled registry cleaning, plus more advanced options to improve system performance and create system backups.

Auslogics Registry Cleaner is the only app on this list that only cleans the registry and nothing more. But perhaps this is the main advantage of Auslogics Registry Cleaner compared to its competitors, since it focuses on one task. The application interface is classic, allowing you to select those registry categories that should be cleared.

Auslogics Registry Cleaner can create a backup copy of the registry before making changes and restore the old version if something goes wrong. It also has the function of searching and removing registry keys manually (for example, to search for viruses if they have left traces in the registry).

Is CCleaner in last place? This can't be true! Even though CCleaner is arguably the most effective registry cleaner, many experienced users have noticed that it tends to be too aggressive in cleaning the registry. It happened that CCleaner also deleted useful keys, which were then difficult to recover.

But if you are careful, then CCleaner may come in handy.

The free version of CCleaner is more than sufficient for inexperienced users. For $25 you can purchase the CCleaner Pro version. It introduces additional functionality: scheduled cleanups, real-time system monitoring, automatic updates (the free version requires you to manually update the app yourself) and premium support.

If there is one reason to avoid cleaning the registry, then don't do it. Of course, you won’t get any serious problems by using the above utilities, but as they say: “God takes care of the best.”

Always create backups before you start cleaning the registry and optimizing the system as a whole.

There may be another reason for the computer's slow operation, for example, a virus or hardware problems. Therefore, first of all, deal with the issue of choosing and installing an antivirus, if you do not already have one.

How do you feel about cleaning the registry using utilities? Which ones do you trust? It might be worth mentioning this in the comments if it's worth mentioning.

I continue to frantically “storm” (update) old reviews of useful programs on the site, taking new screenshots (installers and interfaces are constantly changed by the authors of the utilities), replacing links with relevant ones, adding videos to EVERY article...

The turn has come to the magnificent and legendary program. I recommend getting to know her - it’s not for nothing that she lives in the “” section on the resource.

Hello, friends! Due to the enormous popularity of the topic “ System optimization"I present another utility from this category. Today we will learn how to clean the Windows registry.

First, I’ll try to explain “on my fingers” what kind of animal this is. The Windows registry is the holy of holies of the operating system. A list of everything that is in the system. An entry about a program, file, function, driver, setting... is entered into the registry. Not a single action is complete without referring to this list. Starting Windows, any program... occurs only after checking with it.

Now imagine how important the size of this list and its cleanliness are. The program was deleted 10 years ago, and there is an entry about it in the registry (not all programs can be removed from the system correctly). Each time, she searches anew among such digital garbage for the record she needs at the moment. Over time, the list swells to obscene sizes and the computer slows down.

P Windows registry optimization program

I’ll tell you a secret - you can clean the Windows registry, compress it, defragment it... optimize it in every possible way. There are special programs for these actions. Let's look at one of them today. - an easy, simple, free program for registry optimization, step by step and in pictures!

Any tweaker program works on the principle of changing registry entries. The smaller its size, the faster Windows, the processes inside it, and computer programs start and run.

You need to optimize the registry- any specialist will say. But there is no need to show fanaticism. It is enough to use Registry Life once a month and the system will be grateful.

To use the program you do not need to have any special knowledge. She will check everything herself, find errors and correct them.

At the beginning of the work, a backup copy of the important list is created and you can always roll back the changes. Nothing unnecessary will be deleted - Registry Life is a smart program.

One of the factors affecting the performance of the operating system is the state of the system registry. If the system starts to slow down, it may be registry optimization will help fix this and speed up its work.

The system registry stores the parameters and settings of hardware and software necessary for the correct operation of the operating system. Almost all changes made to the system when installing programs, working with the Control Panel, etc. are made to the system registry. In fact, The Windows Registry is a database of settings and options, built on a hierarchical principle.

The system registry is divided into sections (branches). Each section contains folders in which system parameters and settings are stored. The more changes are made to the system during operation, the more the registry grows. Over time, erroneous parameters appear in it (for example, if some programs were removed incorrectly). In addition, the registry is subject to fragmentation, which slows down work with the registry.

Optimizing the registry helps to organize it and, accordingly, speed up the system. Typically, registry optimization involves several operations at once.: cleaning the registry from defective and outdated entries, compressing and defragmenting the Windows system registry. The size of the registry is reduced, and the speed of accessing the registry increases.

Windows has built-in utilities for working with the registry - regedit.exe and regedit32.exe. However, an inexperienced user should not use them to optimize the registry, since they are primarily focused on manual work with the registry. If you are not familiar with the system registry, you may delete something that is not right, and this will lead to system malfunctions. You may even have to reinstall the OS.

Therefore, it will be more effective and safe registry optimization using special programs for working with the registry. Such programs automatically find existing problems in the registry and fix them, perform compression, etc. Let's take a closer look at several of these programs.

One of the most popular programs for registry optimization is CCleaner.. This program is free and suitable for both 32-bit and 64-bit systems. Registry optimization is just one of the options in the CCleaner utility, designed to optimize the operation of the operating system as a whole.

To optimize the registry, run the program, go to the “Registry” tab and click the “Search for problems” button. The program will scan the system registry for a number of parameters (from incorrect file extensions to missing applications) and display a list of problems found. If you wish, you can choose which parameters will be used for scanning. by checking or unchecking the corresponding parameters.

When working with this program, it is not necessary to do the following: before correcting errors in the registry the program itself will offer to make a backup copy of the changes made. If the registry optimization goes wrong and the system starts to crash, you can always restore the registry to its original form from the REG file saved by the program.

Another program for registry optimization is called Registry Life. This free utility from Chemtable is used to optimize the registry and supports both 32-bit and 64-bit Windows operating systems. When you start the program, the program will scan the registry for errors and the degree of fragmentation and make a verdict: whether cleaning or optimizing the registry is really required.

During the cleaning and error correction process, the program finds and removes unnecessary and erroneous registry entries, compresses the registry files, and then defragments them. You can set up automatic optimization, launched according to a schedule with a certain frequency.

Regular registry optimization using special programs will help speed up the system, but do not forget that the performance of the operating system is influenced by other factors that also need to be taken into account.
