How to Clean Windows 10 Registry Entries?
Windows register is a database or repository for a big volume of data about your computer. It stores information about the DLLs that are shared among applications in the PC, listings in menu shortcuts, application settings, driver information and Windows settings. Basically it records any action you perform in your Windows system. The Windows registry therefore consolidates all Windows system settings across all applications in use.
Why Should You Clean Windows Registry?
Apart from providing a repository for all user settings, the registry is read into the Random Access Memory (RAM) during boot time. That's said, why do we need to clean Windows registry? If you take a sneak peek into the Windows registry, you’ll discover that it gets cluttered over the period of time and usage. This is because Windows registry doesn’t clean up automatically and efficiently. It consistently creates new files but hardly ever removes old entries that are no longer required.
