Windows is a complex operating system and this is what gives users the capability to customize it almost endlessly.
You can change almost any element in Windows, and for this reason, it is one of the most used operating systems on the planet.
Windows was designed to store all the important information and settings inside registry files, contained in the registry.
Let’s explore each of these elements so we can better understand how they function and why they exist in the first place.
What are registry keys used for?
As mentioned above, keys are ways through which your registries are organized based on their functions, and there are 5 in total:
Each of these keys holds specific information, so those that have a certain experience with such things can easily modify their PC’s settings en-masse just by changing a few digits in the right registry.
However, keys aren’t the only thing that makes up the Windows registry, as it is also composed of different value types:
- String value
- A multi-line string value
- Unlike the previous value type, this is an expanded string value
- As the name says, this is a binary value
- This is similar to a binary value, but also supports 32-bit decimal and hex values
- This is similar to DWORD but it’s stored as a 64-bit value

What is a broken registry item?
In simple terms, broken registry items are corrupted or deleted registries that affect the way your PC works. This situation usually occurs when the values are not set properly or have been changed because of some third-party or manual incurrence.
Their existence can lead to a variety of problems, including frequent errors, the inability to open apps, driver issues and hardware unresponsiveness, BSoD errors, and more.
Broken registry items can be caused by frequent installs and uninstall of software on your PC, or even tampering with those while not knowing exactly what you’re doing.
Fortunately enough, there are ways of tracking any changes that occur with your registries, and this can be done with the help of dedicated registry monitoring tools.
Alternatively, there are even ways through which you can undo registry changes altogether, and while these usually involve a certain degree of skill and experience, following the steps described in the guide linked above will surely be of help.
But when you have so many things to keep track of, the registry can get pretty messy after a while and you’ll end up having to clean up your registry.
How can a registry editor improve your PC’s performance?
Besides solving any sort of issues that might be caused by a faulty registry value, there are many other benefits to using a good registry cleaner tool on your PC.
Here are some of the most common related improvements:
➡ Boosting your PC performance
Even though in this case the exact registry cleaner tool you would use has a great significance, the optimization of all the values in the registry of your PC could improve the processing speeds of your system considerably.
In the same way that a cluttered hard drive (even without errors) affects the speed at which the data from the HDD is being read, the clutter of registry items causes the same slow-down effect.
Having any registry items that are not of use removed will enable your system to process the remaining ones even faster than before, as your system will not waste any more time processing useless data.
Beyond this, the optimization of the remaining registry files will involve setting the correct values and even modifying their location inside the hives and keys.
➡ Enabling a faster booting process
Not all software presented in this list is equal when it comes to the improvement in your system’s booting times either.
As you can see from the graph above, while not having your PC’s booting time optimized takes a lot longer, using a registry editor with this capability can greatly improve the scores.
Restoro comes at the top with the best results and is closely followed by Iolo System Mechanic and IObit SystemCare.
Even though the others improve the booting times as well, the chart shows the difference between them.
Choosing the right software to optimize will depend very much on firstly identifying if you need a simple program that does only one job, or you wouldn’t mind having some extra useful features.
Our recommendation is to go for the software that offers a variety of capabilities, as even if at this point in time it might seem that they’re not useful, in the long run, you won’t regret it.
It’s always good to have software that can optimize your registry values. Added to that, using only one software to also improve booting times and speed is the most efficient.
