Before we go into how to clear your Windows 10 registry, a word of caution: if you delete anything, be extremely careful.

If you don’t know what you’re doing, there’s a good chance that your programs and operating system will stop working correctly. At your own peril, follow these rules.

Before you start deleting items, we recommend establishing a Restore Point and a backup of your registry as it is.

What is the best way to clean the Windows 10 Registry?

1. Make use of a registry cleaning from a third-party service

Windows Update is designed to improve your operating system’s overall efficiency, integrate new features, and even upgrade old ones. However, there are situations when mistakes happen out of nowhere.

2. Using Registry Editor to clean the Windows 10 registry

  1. Enter regedit by pressing Windows Key + R.
  2. Now hit Enter or OK to continue.

You can also utilize the Search box by typing the following into it:

  1. Enter regedit into the Search bar. The Windows Key + S shortcut can also be used to open the Search bar.
  2. From the list of options, choose regedit.

It’s a good idea to back up your registry before cleaning it. Removing specific registry items can result in various issues, so make a backup of your registry before proceeding. To do so, go through the following steps:

  1. Select File > Export from the File menu.
  2. Select All as the Export range now. Click Save after entering the appropriate file name and selecting a safe place.

If you have any problems after making changes to your registry, you can simply execute the file you just made to restore it to its previous condition.

Searching for registry entries of applications you’ve uninstalled is the most straightforward approach to achieve this. Navigate to HKEY CURRENT USER and then Software using the left-hand navigation panel.

You’ll find a list of everything installed on your computer here. Look for any programs you’ve recently uninstalled.

Select them and press the Delete key on your keyboard if you come across any. You can also use the Ctrl+F shortcut to find a specific entry.

If you want to go this route, be cautious since it’s gone forever once you delete a registry item.

There is no way to undo this, so proceed with caution. If something goes wrong, you can restore the registry using the file you made before starting.

Windows’ default tool for examining and editing the registry is the Registry Editor. However, conducting a manual search takes a long time, and sorting through the thousands of results might be difficult.

This is why we advocate cleaning the registry via a third-party program, as they will create a backup of the Windows registry before cleaning it.

Why is it necessary to wipe the registry?

Everything you do on your computer leaves a trail in the registry. Every software you install, every website you visit, and every modification you make creates a registry record.

When you consider that each and every function you perform on your computer creates its own registry record, you can understand how many there are.

While registry keys take up very little space on hard drives, they make up for it in huge numbers.

After a period of time using Windows 10 and downloading and removing programs and apps, hundreds or thousands of registry entries are created that are entirely meaningless.

Even if they aren’t utilized anymore, the operating system still filters through them all, and this process slows things down, as I’m sure you’ve noticed when opening a folder with hundreds of files or copying many files.

Even with all of the changes and improvements, it’s evident that Windows 10 can’t handle file systems with a large number of entries.

This is most likely due to hardware restrictions rather than software, but we can still improve it.

Before you start cleaning your Windows 10 registry, make sure you have a backup

Make sure your PC doesn’t have any running programs. Before you begin, make sure everything is turned off except the registry cleaning utility.

Active programs add and modify registry entries, which may cause the scan to fail or potentially damage the registry.

Also, do not interfere with the computer in any way while the scan or repair procedure is running. Even renaming a folder or moving a shortcut creates a registry record, jeopardizing the entire operation.

Some registry cleaning programs evaluate each register’s danger and determine which ones are safe to change or clean.

Remember to choose just the registry items that the application suggests and not any of the registry entries that are flagged as dangerous to change.

Also, if your registry software has an auto-delete feature, make sure to turn it off. It’s preferable to have complete control over which entries should be erased.

Everything should operate smoothly after the scan, but if it doesn’t, and particular software stops working, you should immediately restore the registry to the state it was before you changed it.
