I make technology videos, including tech news, reviews, and discussions. I also try to make complex topics not-boring.

The registry keeps track of all the settings used by the operating system and the applications that run on it, including the user preferences and configurations. It is used to store information such as the system settings, user settings, hardware settings, and application settings. It is a very important part of the Windows operating system, and it is essential for the smooth operation of the system.&#160;</p><p>HKEY stands for &quot;Handle to Key&quot; and is a way of organizing the registry into sections. This is done to make it easier to find settings and data. The registry is divided into five main sections, each of which is known as a &quot;hive&quot;. The five hives are HKEY_LOCAL_MACHINE, HKEY_CURRENT_USER, HKEY_USERS, HKEY_CLASSES_ROOT and HKEY_CURRENT_CONFIG. Each of these hives contains subkeys and values that can be used to store various settings.&#160;</p><p>The settings that are stored in the registry are used to configure the system and the applications that run on it. This includes the settings for the operating system itself, as well as settings for applications and programs that are installed. The registry provides a central location for settings for the operating system, as well as for user preferences, hardware settings, and application settings. It is also used to store driver information and other settings that are used by the operating system.&#160;</p><p>The registry is an important part of the Windows operating system, and it is essential for the smooth operation of the system.

The Registry contains information that Windows continually references during operation, such as profiles for each user, the applications installed on the computer, and the types of documents that each can create, property sheet settings for folders and application icons, what hardware exists on the system, and the ports that are being used.</p><p>In Windows, including Windows 11, the Registry is organized into five main categories, also known as hives. Each hive contains a tree of keys and values. These five hives are&#58;</p><ol><li><p>HKEY_CLASSES_ROOT (HKCR) - Contains information about registered applications, such as file associations and OLE Object Class IDs, tying them to the applications used to handle these items.</p></li><li><p>HKEY_CURRENT_USER (HKCU) - This hive is a link to the subkey of HKEY_USERS appropriate for the user currently logged onto the PC and contains information such as logon names, desktop settings, and Start menu settings.</p></li><li><p>HKEY_LOCAL_MACHINE (HKLM) - Contains computer-specific information about the type of hardware, software, and other preferences on a given PC, this information is used for all users who log on to this computer.</p></li><li><p>HKEY_USERS (HKU) - Contains individual preferences for each user of the computer, each user is represented by a SID subkey located under the main key.</p></li><li><p>HKEY_CURRENT_CONFIG (HKCC) - Contains information about the current hardware profile of the computer.</p></li></ol><p>Be aware that making changes to the Windows Registry can have significant impacts on the functioning of your system. Changes should only be made by advanced users who understand the implications of modifying Registry keys and values.</p></div></div><div data-sp-canvascontrol="" data-sp-canvasdataversion="1.0" data-sp-controldata="&#123;&quot;controlType&quot;&#58;0,&quot;pageSettingsSlice&quot;&#58;&#123;&quot;isDefaultDescription&quot;&#58;true,&quot;isDefaultThumbnail&quot;&#58;true,&quot;globalRichTextStylingVersion&quot;&#58;0,&quot;rtePageSettings&quot;&#58;&#123;&quot;contentVersion&quot;&#58;4&#125;,&quot;isEmailReady&quot;&#58;false&#125;&#125;"></div></div>
