System registry. Optimization

Registry Life - free application(from the creator of the popular Reg Organizer tool) that allows automatic cleaning system registry Windows and optimize it.

The utility will help fix errors in the registry, as well as optimize it to improve the performance and stability of the Windows system. Registry Life is an easy-to-use solution for maintaining your system's registry.

The system registry is one of the important components operating system Windows. The stability of the system depends on the state of the registry, and the speed of execution of programs that you constantly work with on your computer depends on the volume of data it contains.

A new computer always runs at peak performance. However, everyone notices that the performance of the system is gradually decreasing. The Registry Life utility can reduce the impact of this effect, affecting the two main reasons for the slowdown in the speed of your computer. One of the reasons is the appearance of errors and unused data (garbage) in the registry. Another reason is fragmentation and an increase in the size of the system registry due to unused space in the files where it is recorded.

Main features of Registry Life

Correcting errors in the registry.

To identify errors and clean up unnecessary data in the registry, Registry Life offers a convenient and easy-to-use Registry Checker tool. Using it, you can check the system registry for the presence of more than 10 various categories problems. At the same time, the program will remove unnecessary data from the registry.

Registry optimization

The Registry Optimizer tool in Registry Life defragments and compresses the registry. The utility quickly and effectively optimizes the Windows system registry, visually presenting the result of the optimization process.

Autorun programs

The startup optimization tool allows you to delay the launch of most programs that start at system boot by specifying an arbitrary period of time after which the application will be launched. Postponing programs that are not needed immediately after the system boots allows you to speed up bringing Windows into a working state, i.e. When user interface operating system and third-party software starts working without delay.

Some myths surrounding Windows optimization, persecute us in articles, on websites, in tweaking programs. However, they have nothing to do with reality, so following these tips can only cause harm. Here are examples of such myths.

Disabling QoS to free up 20% bandwidth networks

This advice is used by people who believe that Microsoft always allocates 20% of the network channel for Windows Update. According to the instructions, you need to turn off QoS and free up bandwidth. Unfortunately, this advice not only does not help, but can also add problems with applications that use QoS, such as streaming media and VoIP.

Here's Microsoft's official response: “Many articles and newsgroup posts claim that Windows XP always reserves 20% of available network bandwidth for QoS. This is not true... One hundred percent of the network channel is available to all programs unless one of them requests priority in the channel.”

Allow Vista to use multiple cores to speed up boot times

This false advice appeared recently, and almost everyone believed it. According to it, in the msconfig utility it is necessary to modify the value in the “Number of processors” drop-down list on the “Loading” tab. This value is really only used for troubleshooting and debugging purposes, to identify a problem with a specific processor, or to allow a programmer to test their code on a multi-core system. Windows uses all processors by default even without this setting.

Cleaning out the Prefetch folder for faster loading

Windows XP's Prefetch app caches parts of the apps you use frequently and tries to optimize the boot process to make apps launch faster, so when many sites started suggesting periodic cleaning to speed up boot times, it seemed good advice... but, unfortunately, incorrect.

The preload feature is actually used as an index to tell Windows which parts of the application to load into memory and in what order to speed up the application's launch, but Windows does not use this information before the application starts running. There is also a limit of 128 files that can be saved in the Prefetch folder at any time, and Windows itself automatically cleans out this folder, removing information about unused applications. In addition, a good defragmentation utility uses Prefetch information to optimize files on disk, making access to them even faster.

Cleaning the registry improves performance

The Windows Registry is a large database containing virtually every setting for every application on your system. It makes sense that cleaning it would speed up the work, right? Unfortunately, this is just a marketing hype designed to sell registry cleaning utilities, and the reality is anything but... Registry cleaners only remove a very small number of unused keys, which won't help performance given the hundreds of thousands of other keys in the registry.

This is not to say that these utilities are completely useless, of course. I would still recommend cleaning the registry when you are trying to fix the issue of uninstalling problematic apps leaving behind registry entries, but you should use a trusted app and check the keys being removed.

Clean up memory using “Task Processing in Your Free Time.”

At this point you should be slowly starting to realize... If something sounds too good to be true, it is most likely a scam. Another tip is that you can create an “undocumented shortcut to the command Rundll32.exe advapi32.dll,ProcessIdleTasks, which will clear the memory by processing all tasks occupying memory in the background.

What's the problem? These tasks aren't actually waiting in the background. This command actually tells the computer that you are away and it can process tasks while the computer has some free time. But you didn't leave. The real purpose of these functions is to train all tasks before running performance tests so that they time correctly, and the Microsoft documentation says this: “When called from command line ProcessIdleTasks runs asynchronously in background. Background tasks may take 10 to 15 minutes to complete. The task manager reports running processes, and the disk may be active at this time.”

Clean, defragment and speed up RAM with Super Mega RAM Optimizer
Look at any software website and you will find thousands of programs that promise to “optimize memory to speed up your computer.” Don't believe it! Almost all of these programs do the same thing: they call the EmptyWorkingSet() function, which causes applications to send data from memory to the page file, or they allocate and free huge amount memory, so Windows has to throw other applications into swap.

The result is an apparent freeing of memory, but in reality you just traded your space-fast RAM for a slow disk. As soon as you have to return to the application you are working with, you will want to throw out the computer and stomp on its mortal carcass.

Disabling System Shadow Copy and Restore improves performance

There don't seem to be any sites with advice on Windows Vista, which advise against turning off System Restore to speed things up because it uses up to 15% of your disk by default. This seems like good advice. But this is bad advice.

In reality, System Restore only works when you install an application or update, or at a designated time of day, and automatic restore points are created only when you are not at the computer. This is critically important because it allows you to restore the machine to its previous condition, eliminating problems.

Instead of disabling System Restore to free up space, use the Disk Cleanup wizard to delete all restore points except the last one.

Enabling SuperFetch in Windows XP.

Someone decided to spread the myth that you can enable SuperFetch in Windows XP by adding the same EnableSuperFetch key used in Vista to the registry. This advice is completely false.

Disabling services to speed up your computer

The most common myth is the advice to delete all unused services. I realize this may be controversial, so I'll clarify that disabling non-critical services that are not part of Windows can sometimes result in improved performance if you determine that those services are causing problems. You can identify and disable these services in the “Services” tab of the msconfig.exe utility.

The problem with disabling services is that your devices may stop working afterward, and the problem can be difficult to pinpoint if it's not immediately apparent.

Do not disable built-in Microsoft services in Windows, except in certain situations:

SuperFetch- this caching service preloads applications into memory and really helps. However, it causes intense work hard drive, which is annoying and disturbing, especially on laptops.

Windows Search- if you use another local search engine, you don't need this service and disabling it can actually improve performance.

Windows Defender- if you use another anti-malware product, you don’t need this service either.

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

Back in the early 2000s Windows registry was one of the biggest performance bottlenecks. Hard drives and the processors were slow, and the registry itself was poorly optimized, which forced the operating system to look for the required 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 recommended by registry cleaners.

If you have a slow hard drive, then registry optimization may 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 - great tool"all-in-one" but provides an easy 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 files Junk Email), Shortcut Cleaner (invalid shortcuts to files and START menu items), and Cleanup RAM RAM (for memory leaks).

Other useful features include system startup optimization, Internet connection acceleration, 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 Pro for $20 plus $15 per year as subscription fee. 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 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).

CCleaner on last place? This can't be true! Despite the fact that CCleaner is perhaps the most effective tool to clean the system registry, many experienced users have noticed that it tends to clean the registry too aggressively. 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 CCleaner version Pro. It provides additional functionality: scheduled cleaning, real-time system monitoring, automatic updates (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 protects the best.”

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

There may be another reason slow work computer, 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.

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 parameters and settings of the hardware and software necessary for correct operation operating system. Almost all changes made to the system when installing programs, working with the Control Panel, etc. are made to the system registry. Essentially 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 in automatic mode find existing problems in the registry and fix them, perform compression and . 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 serves for registry optimization and supports both 32-bit and 64-bit OS Windows family. 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 registry optimization 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.

One of the most important points in optimizing the Windows operating system is cleaning the system registry. Ask what you can clean such an OS partition from? But as it turns out in practice, many things...

Let's start with the fact that when installing programs, many entries are made into the system registry (these are program settings, location, etc.), and when deleting a program, not all entries associated with the program being removed are cleared during the uninstallation process

  • Uninstallation is the process of removing a program without the possibility of recovery, when this process All information about the product being deleted is deleted. Typically, a built-in uninstaller (like Uninstall.exe) is used for uninstallation.

This leaves behind records that make it difficult for the system to access the requested applications. Also, the system registry may over time undergo changes from the system, this problem is in no way related to the user's activities.

Since the system registry reflects all system and software changes, it is most dependent on cleaning to maintain stable operation.

  • The Windows Registry, or system registry, is a hierarchically built database of parameters and settings in most operating systems Microsoft Windows. The registry contains information and settings for hardware, software, user profiles, presets. Most changes in the Control Panel, file associations, system policies, and the list of installed software are recorded in the registry. The Windows registry was introduced to organize information previously stored in many INI files, provide a single mechanism (API) for writing and reading settings and get rid of the problems of short names, lack of access rights and slow access to ini files stored on file system|FAT16, which had serious performance problems when searching for files in directories with a large number of them. Over time (finally, with the advent of NTFS), the problems solved by the registry disappeared, but the registry remained due to backward compatibility, and is present in all Windows versions, including the last one. Since there are currently no real prerequisites for using such a mechanism, Microsoft Windows is the only (not counting ReactOS) operating system in use today that uses the operating system registry mechanism. (Material from Wikipedia, the free encyclopedia)

Windows does not provide any means to clean this component of the operating system. The only thing that OS developers offer is a registry editor - Regedit

  • Regedit is a registry editor built into the operating system that has all the required functions for making changes to entries. It is a window divided into two parts, the left one – registry sections, and the right one – entries and values. To call this editor In the Run window (Win + R) type: regedit

To find and eliminate problematic registry values, there are special utilities– operating system optimization programs. They scan and automatically fix damage to the system.

One of similar programs, is . This multifunctional tool OS optimization. Russified interface, convenient control and free use do it for personal purposes this program an irreplaceable assistant.

  1. To clean the system registry, install CCleaner program to your computer. Run the program - in any way available to you. In the main window on the left side, click the “Registry” button
  2. Afterwards you can select the sections and problems that the program should scan.
  3. Click the button at the bottom of the "Search for Problems" window
  4. Wait until the search process completes.
  5. After that, the “Fix” button will become active - click!
  6. A save notification appears backup copy registry for recovery.
  7. Click the “Yes” button to agree to the creation this file, you can specify any save location or use the default location – “Documents”
  8. Click the Save button.
  9. Afterwards a window will be displayed to start fixing, select the “Fix marked” button
  10. Wait for the execution process to complete.
  11. Then click the Close button.

All! The system registry has been cleaned. When finished, you will return to the main window, which you can close.
