What is Registry?
Windows Registry is a hierarchical database that stores configuration settings and options on Microsoft Windows operating systems. It contains settings for low-level operating system components and for running applications.
The data stored in the registry varies according to the version of Microsoft Windows.
Note :- You should not edit registry data that does not belong to your application unless it is absolutely necessary. If there is an error in the registry, your system may not function properly.
Before you make changes to a registry key or subkey, we recommend that you export, or make a backup copy, of the key or subkey. You can save the backup copy to a location you specify, such as a folder on your hard disk or a removable storage device. If you make changes that you want to undo, you can import the backup copy.
