? Find all about broken registry items
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.
One of the first steps in troubleshooting a registry problem is to find the affected key manually or touse a dedicated Registry key finderto locate it.
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 ofdedicated registry monitoring tools.
Alternatively, there are even ways through whichyou 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:
Even though in this case the exact registry cleaner tool you would use has 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.
Talking about improved performance, if you have made the big step to the new OS, we havea selection of the best registry cleaners for Windows 11that will help you with that.
Not all software presented in this list is equal when it comes to the improvement in your system’s booting times either.
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.
Fortect 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.
It’s important to note that all the software from this list or recommendations work on Windows 11 too so if you upgraded, you will still be able to use them.
If you didn’t do that yet,check our guide on how to download Windows 11 ISO or update from Windows 10and keep up with the trends.
Choosing the right software to optimize will depend very much on first identifying if you need a simple program that does only one job, or if you wouldn’t mind having some extra useful features.
Our recommendation is to go for software that offers a variety of capabilities.
If you’re still using the old Windows 7, we also havea list including the best registry cleaners for Windows 7that still work fine for that OS.
