What does registry key value mean?

Registry keys represent Windows system registry entries. Through editing and modification, you can change or optimize Windows operating system-related functions and performance.

Registry keys can be thought of a bit like folders, but they only exist in the Windows registry. Registry keys contain registry values ​​just like folders contain files. Registry keys can also contain other registry keys, sometimes called subkeys.

Note: Registry keys work the same way in all versions of Windows. There have been some changes to the way registry keys are crashed and expanded, but these changes are very minor and do not affect their functionality.

In the registry, all data is organized in keys and subkeys through a tree structure, which is very similar to a directory structure. Each key contains a specific set of information, and the key name of each key is related to the information it contains. If this key contains subkeys, there will be a " " symbol to the left of the folder representing this key in the Registry Editor window to indicate that there is more content in this folder. If this folder is opened and expanded by the user, then this " " will become "-".
