How The Windows Registry Works

How The Windows Registry Works

When you install a program on your computer’s hard drive, it receives instructions and file references. These are placed in the correct location.

It is used by the operating system to find out more about file locations, options, how to use the program, installing new software, changing your hardware, etc.

However, not all Windows applications use the registry. Some applications store configurations in XML files, while portable types store data in the executable files.

The Registry Editor is a free tool that comes with all Windows versions since Windows 95. It allows you to access and configure the registry.

The registry editing utility that is free to download is not the registry. It’s just a tool through which you can view it and make changes. It can be accessed via the Command Prompt and executed with the Regedit command.

Alternatively, click Start and choose Run. To open the Registry Editor, type regedit.exe into your browser and hit OK.

Registry values, registry keys, as well as registry hives are all contained within the registry. Registry keys contain instructions that can be used to create registry values. These registry keys are data folders that contain data. These are located in several folders which categorize registry data within subfolders. They are also called registry hives.

You can make changes to keys or values through the Editor. This will affect the configuration that is controlled by a particular value. You can also make changes to any registry setting, but some won’t take effect until your computer is restarted.

This is why it’s so important to be able to understand what you are doing when you edit the registry via the Editor.

Note: Make sure to back up your registry before you make any changes.

Problems Caused By a Corrupt Registry

The computer might not start if the registry is corrupted. This happens most often when the computer is turned off.

Registry hives can also be corrupted by unexpected shutdowns or power failures. This could happen when a process was modifying a part of the registry, and then suddenly, the power or shutdown stops the process. The registry hive becomes inconsistent, and the operating system will attempt to load the hive, but it won’t find the data it needs, leading to error messages.

Your registry and any other data can be corrupted if your files are damaged, or your hardware is faulty.

Registry corruption can also occur during a shutdown. You may not notice it until you try to load it at your next restart. The hive is written during the shutdown. This can cause the computer to stop working or even crash.
