Best Registry Cleaners for Windows 10

The registry is a Windows database that stores platform configuration settings and most software. You can open the Registry Editor window by pressing the Win key + R and then entering ‘regedit’ into Run’s text box, or open it with third-party software covered in this Tech Junkie guide. There you can add or delete registry entries, but it’s not recommended to manually erase anything with the Registry Editor. Registry cleaner software packages are utilities that scan for and erase less essential entries from the registry.

There are a few things to note about registry cleaner software. Firstly, registry cleaners will be more effective on outdated laptops and desktops with antiquated Windows platforms that don’t maintain the registry as efficiently as Win 10. Secondly, poorer registry editors might not boost system performance at all; and might even undermine it by deleting more essential registry entries. However, the better registry cleaners will at least erase registry entries left over from software you’ve removed; so they might free up a few megabytes of hard drive space and fix some issues. These are some of the best registry cleaners for windows 10 and other platforms.
