How to clean the Windows 10 Registry

Clean registry errors

Here, you will find a list of everything that is installed on your PC. Look for programs that you’ve uninstalled, and if you find any, simply select them and hit the Delete button on your keyboard. Also, you can use the Ctrl+F shortcut to search for a specific entry.

If you decide to go down this road, then you have to be very careful, as once you’ve deleted a registry entry, it’s gone.

There is no undo option here, so be very careful. If something does go wrong, you can back up the registry with the file that you created before you begin.

The Registry Editor is the Windows default tool for viewing and modifying the registry. However, this manual search is very time-consuming and filtering through the thousands of entries can be quite hard.

This is why we recommend using a third-party tool to clean the registry, as these will create a backup of the Windows registry before starting the cleaning process.

Why do we have to clean the registry

Registry entries are the footprints of everything you do on your computer. Every installed program, every webpage opened, every change you make creates a registry entry.

You can imagine how many of these registry entries exist if you consider that each and every operation you do on your computer makes its own registry entry.

While registry keys occupy next to nothing on hard drives, they do, however, make up for it in sheer numbers.

After some time of running Windows 10 and installing and uninstalling programs and apps, you end up with hundreds or thousands of registry entries that are completely useless.

The operating system still filters through all of them, even if they are not used anymore, and this process burdens it, as I’m sure every one of you has seen at one point when you open a folder that has hundreds of files, or when you copy multiple files.

We can clearly see that even with all the upgrades and improvements, Windows 10 can’t manage file systems that have a huge number of entries.

This is probably due more to hardware limitations than to the software, but even so, we can make it better.

Before you begin cleaning your Windows 10 registry

Make sure that there are no running programs on your computer. Close everything except the registry cleaning utility before you begin.

Active programs create and modify registry entries, so they might interfere with the scan, or they might even become damaged.

Also, while the scan or the repair process is running, don’t interfere in any way with the computer. Even a simple rename of a folder or a moved shortcut creates a registry entry and might compromise the entire process.

Some registry cleaning programs assess the risk of each registry and tell which of them are safe to modify or clean.

Keep in mind to select only those that the program says, and do not select any of the registry entries that are marked as risky to modify.

Also, if the registry utility that you use has an auto-delete feature, be sure to disable it. It is better that you have control over what entries should be deleted.

After the scan is complete, everything should be running smoothly, but if this isn’t the case, and certain software doesn’t work anymore, you should immediately restore the registry as it was before you modified it.

If the problem persists, you should use the restore point you created before starting to revert to the original state of the registry.
