How to clear registry in windows 10 as so many leftover there

I suggest using a registry cleaner software instead. It is one of safest ways to clean registry in Windows 10.

A registry cleaner is a software utility designed to scan the Windows Registry for outdated, invalid, or redundant entries. The Windows Registry is a massive, centralized hierarchical database that stores low-level settings for the operating system and for the applications that run on it.

Over time, as programs are installed, uninstalled, and updated, this database can become cluttered with references to files that no longer exist, broken shortcuts, and orphaned keys from programs that were not removed cleanly. The primary function is to identify and clean registry for Windows 10.

The theory is that by removing unnecessary entries, the operating system can search the registry more quickly, potentially leading to faster boot times and more responsive application launches. Furthermore, it is suggested that some system crashes or application errors can be caused by corrupt registry entries, and removing them could resolve these issues, leading to a more stable computing experience.
