Key notes

  • Proper computer maintenance is something that is often overlooked by the majority of people.
  • It’s important to keep your Windows 11 computer registry clear of junk in order to maintain high performance.
  • This guide lists the best eight registry cleaner apps on Windows 11.

Computer maintenance is incredibly important in making sure everything on the system runs smoothly; however, most people just aren’t well-versed in taking care of their computers.

At some point, most will notice their computer’s performance degrading, but are unable to understand why.

A likely reason because every time you do something on your computer, it leaves behind a trail. Whether you’re installing an app or even changing something slightly, junk files can begin to clutter up your device. Uninstalling apps can also bloat the registry.

That’s why it’s important to utilize a registry cleaner app to sweep out all the junk in a computer. Windows 11 already has its registry in the form of the Windows Repair app.

But like with a lot of the native apps on Windows 11, there’s is a third-party app that does it much better. While registry cleaning apps aren’t something that a lot of people pay attention to, they can be game-changing.

Does Windows 11 have a built-in registry cleaner?

Windows 11 doesn’t come with a built-in registry cleaner, leaving users to handle registry edits manually. This manual process can be quite tedious and time-consuming. For a more efficient approach, consider using one of the specialized registry cleaner tools highlighted in our list below.

Is a registry cleaner that important?

Registry cleaners are more than just a convenience: they’re essential for maintaining your computer’s performance. Over time, junk files accumulate and can slow down your system, making these tools as crucial as antivirus programs. They’re safe to use and highly recommended for regular computer maintenance. Most of these apps offer both free trials and premium versions with additional features, so you can choose the one that best suits your needs.

What are the best registry cleaner options for Windows 11?

Fortect – Straightforward application

Wise Registry Cleaner – Most intuitive interface

Wise Registry Cleaner is one of the better-looking cleaner apps with an easy-to-understand user interface; something not many other tools have.

Sometimes a registry cleaner can be not user-friendly and look intimidating. But Wise’s clean and simple layout earns it big points.

The tool creatively uses its layout. When done scanning, Wise presents its findings in a sheet, similar to how Microsoft Excel displays its information.

It has fast registry scans that can be scheduled for any time, which come in two separate modes: Fast Scan and Deep Scan. Fast Scan is the quicker option while Deep Scan takes its time as it scours through the machine, looking through the nooks and crannies of a PC.

Wise Registry Cleaner is a little light on advanced features, even for its pro versions. But it can be run from the Windows 11 command line, something that most registry cleaners are unable to do. And once you buy it, you don’t have to keep the subscription going.

Most other cleaner apps only allow you to own the tool for a set amount of time before you have to renew your license. Wise Cleaner does not do this and is unique in this regard. Once you buy it, it’s yours to keep forever.

It also offers a registry defrag option. Defragmentation, or defragging, organizes the contents on the Windows 11 registry into regions as a way to optimize the system and improve performance.

Auslogics Registry Cleaner – Most advanced registry cleaner

Auslogics Registry Cleaner is another easy-to-use app. The tool has the distinct feature of the Rescue Center in its settings menu which is a list of registry backups made before each cleaning.

You can edit these settings to backups of the Windows 11 registry if you never want to lose them. As stated previously, registry cleaner apps can overdo it and get rid of things you didn’t mean to delete.

Rescue Center saves those settings in case you want to go back to them.

The user interface is simple and clean, and scanning can be activated at the press of a button. It can be paused at any time and continues later. And one of the nicer things about this app is how it categorizes its findings in a list form.

Auslogics has the unique feature of creating a portable version. Auslogics Portable is a defragging that you can upload to a portable device like a USB drive and take to another computer, be it a Windows 11 machine or not.

The portable version doesn’t have all the features the desktop version has, but it has most of them.

Like Wise Cleaner, everything is situated in a simple format. However, there is an issue with Auslogics that must be mentioned. Upon installation, Auslogics will try to install additional apps during the setup.

While these programs aren’t bad, they can be annoying, but it’s easy to deselect them.

Argente Registry Cleaner – Simple and fast registry cleaner

Argente Registry Cleaner looks a little intimidating at first with its dense-looking user interface, but it uses a wizard to help guide you.

A software wizard, for those who don’t know, is a piece of software that can either simplify a complicated task or serve as a tutorial.

For Argente, its wizard functions as more of a tutorial, guiding you through the process of setting it up so that suits your needs. You won’t have to try and somehow figure out how the registry cleaner works.

With this wizard, Argente scans and repairs the registry on its own. It’s pretty adept at finding out what to get rid of without needing you to configure it. And before deleting corrupt files, the tool lays them all out in an easy-to-understand list.

You won’t have to worry about backing up your data either as Argente has an Undo changes feature that can restore the Windows 11 registry.

Sometimes a registry cleaner can be overzealous and delete things it shouldn’t be deleted, but Argente gives you that extra form of control, so you can undo mistakes.

What are some other ways to better take care of a Windows 11 computer?

As stated earlier, many of the Windows 11 native apps do an alright job at what they do but aren’t the greatest. They lack many of the amazing features third-party apps have.

For example, Microsoft Edge is a decent web browser, but horrible if you are someone who plays a lot of video games.

If you or someone you know plays a lot of video games, you’ll need a web browser that doesn’t take up a lot of computer resources. You’ll need something that eats less RAM like Opera or Firefox if you want the ability to customize with browser extensions.

You may encounter some issues like getting stuck on the Preparing Windows screen. One minute you’re updating the computer and the next it’s stuck on a neverending loop.

How do I clean up a broken registry in Windows 11?

You can delete a broken registry manually (if you know the parameters of the registry file) by opening the Registry Editor, searching for the file, and removing it. Alternatively, you can use one of the tools from the list above. We’ve already written an extensive guide about this.

We recommend Fortect as it’s the easiest to use and can remove any broken registry files in just a couple of clicks.

How do I fix a corrupt registry in Windows 11?

While it is possible to do it manually, in the Registry Editor app, it’s extremely complicated and time-consuming. It requires technical knowledge and it’s risky, as deleting/modifying the wrong registry file can lead to fatal system errors.

The simplest way to fix a corrupt registry is with an automated solution like Fortect, CCleaner, or Wise Registry Cleaner.

It’s important to learn about solutions when even the most basic of Windows 11 functions fail. Sometimes it’s as simple as restarting the computer, but other times it may require a finer touch.
