The Windows Registry is a hierarchical database that stores data, settings, and options for all software and hardware installed on the Windows Operating System. It stores information about the various users created for the system, as well as the best free registry cleaner and Windows preferences.

Why Do You Need the best free registry cleaner Software?
The best free registry cleaner are designed to eliminate invalid registry keys, shortcuts, and other types of errors. Registry cleaners aren’t very effective at improving system performance. Only if your system has thousands of invalid registry keys and errors will you notice a performance hit. It’s a good idea to get rid of any invalid registry entries.
The registry entries left by previously uninstalled software may interfere with the installation of new software. For example, we know that only one antivirus should be installed at a time; you previously had an antivirus installed on your system and are now attempting to uninstall it and replace it with another.
If the previous antivirus software is not completely and properly removed from the system, the new antivirus software may read the previous antivirus’s registry keys and assume that software is already installed on the system, and thus may refuse to install as long as that entry remains in your registry. As a result, after uninstalling programmes, always run your the best free registry cleaner.
