What is the Windows registry?

What is the Windows registry

The Windows registry is a database used to store low-level Windows settings and application settings. The registry is used to store settings for device drivers, kernel, user interface, etc. The registry is used to store device driver settings, kernel settings, user interface settings, etc. Essentially, it stores information such as settings, parameters, and values of software and hardware on all modern Windows operating systems.

Microsoft first introduced the Windows registry in Windows 3.1, which stored COM-based component configuration information. With the release of Windows 95 and Windows NT, the registry was expanded to store data in INI files containing configuration parameters for various programs.

In Windows 95, the Windows registry had a major drawback. If the registry was corrupted, the user had to reinstall Windows. Windows NT fixed this problem somewhat by using transaction logs to protect against corruption during database updates.

Modern versions of Windows use two-level log files to ensure the integrity of the registry in the event of a failure during a database update. In addition, modern versions of Windows can repair corrupt registry entries at system startup.

It serves as a repository of files containing various settings, configurations, and information about the Windows operating system and the applications installed in it. It contains entries that are important to Windows and determines how the operating system works. For example, the Windows Registry stores information such as the location of installed applications, DLL files associated with applications, paths to various files, Start menu shortcuts, etc. The Windows Registry is a file repository that contains various settings, configurations, and information about the Windows operating system and the applications installed in it.

The Windows registry records various aspects of the operating system. Therefore, it is relatively risky to edit it, as you can change the behavior of applications. In the worst case, you can corrupt an application’s registry and the application might stop working.

The Windows registry is not perfect because it tends to accumulate empty and corrupt registry entries. The Windows operating system creates new registry entries every time you boot and use your PC. The problem is that Windows often fails to remove old, unnecessary registry entries.

As a result, if you run the Windows operating system for an extended period of time, installing and uninstalling applications, it gradually accumulates thousands of unnecessary and often defective registry entries, causing the system to slow down considerably. The defective registry entries are corrupted, or the deleted registry entries may be the remnants of uninstalled applications.

Registry entries consume a small amount of disk space, but can significantly slow down your PC because they can bloat your system, consume resources, and cause conflicts. Therefore, you need to remove corrupt, empty, and duplicate registry entries to optimize system performance.

While there are ways to clean your computer’s registry, although there are many third-party applications that can do this for you automatically, you should be aware that these applications can delete valid registry entries, causing additional problems.
Therefore, removing a bad registry entry may cause your operating system or application to stop working properly.

Keep in mind that the Windows registry is a sensitive archive, so manipulating it can do more harm than good. Therefore, we recommend removing broken registry entries using the methods listed below.

Why would you want to delete corrupt registry entries from Windows?

Why remove broken registry entries in Windows

The Windows registry is a repository of a large collection of details about your computer.

If you have been using the Windows operating system for some time and have installed and removed various keyboards and mice, you will end up with hundreds or thousands of registry entries that are completely useless. In addition, there will be several broken entries in the registry.

Although each one takes up very little memory, the operating system still has to delete them, which slows them down a bit. You can remove these broken registry entries and make your system faster.

Common errors in the registry

Common errors in the registry

There are several common causes of registry errors. Some are worthy of concern, others are not.

Orphaned records.
Orphaned entries occur when you uninstall software and small portions of registry entries are left behind. Registry cleaners often claim this is a momentary problem, but they actually consume only a few kilobytes of free hard drive space.

Duplicate keys.
Duplicate keys are created when you reinstall, update or upgrade software on your computer, including the operating system. Registry cleaner claims that your programs are tangled up in duplicate entries and slowing down your computer, but that’s not true.

Fragmented registry.
The registry can also become fragmented when you uninstall, update, or upgrade software.

System shutdown errors.
Every time the computer shuts down, a copy of the registry is stored in the system memory. If the computer shuts down, crashes, or dies without going through the normal shutdown procedure, it may cause a problem in the future, but this is unlikely.

Malware.
Many kinds of malware attack and modify the registry. In particular, malware regularly changes the values of the boot keys so that they are activated every time the PC is rebooted. Registry changes made by malware require immediate attention.
