Registry repair and Cleaning

What Is a Registry Cleaner?

If you own a Windows PC, you’ll be used to performing some basic maintenance tasks to keep it running smoothly and prevent problems with applications or files. Most of us regularly update our virus definitions, empty the Recycle Bin and so on.

When it comes to PC maintenance, a Registry Cleaner should also be part of your toolkit. Its purpose is to keep your Windows Registry tidy, efficient and help applications to run without a hitch.

But What’s the Registry?

Think of the Registry as a database. On every Windows PC, the Registry stores preferences and settings for applications and the Windows operating system itself.

Windows does a good job of keeping the registry up-to-date, but doesn’t tidy up after itself very well. Over time, as you install and uninstall applications, the registry can become littered with old entries. These can cause error messages and slow the computer down. If you want to ensure that your PC functions correctly, and remains fast, you’ll need to clean it up.

Malware

Malicious applications (malware) can also cause Registry problems. Even when the software has been removed, the remnants of that application may remain — causing error messages and slowdowns. Cleaning the Registry can help to remove all this left over data.

Identity Theft

Many applications save data in the Registry, this may include personal information, such as your email address or passwords. After removing the application, some of this data may remain — creating a security risk! Cleaning the Registry will remove this left over personal data and help prevent data theft should someone get access to your computer.

Can I edit the Registry myself?

Technically, you can edit the Windows Registry ‘by hand’. But there are two key reasons not to:

— It’s really easy to change the wrong setting

— If you make a mistake, the consequences might be quite severe. (For example, your PC might refuse to start)

That’s why Registry Cleaners exist — To do the job for you!

Benefits of Registry Cleaner Software

Once your Registry has been cleaned up, you will likely notice a performance boost and any error messages you saw whilst using your computer previously will be gone.

Registry Cleaner will remove entries for non-existent applications, and it’ll also fix invalid or corrupted entries i.e. it will repair your registry. You’ll probably find your computer starts much more quickly too!

How do I fix registry errors?

The great news is that CCleaner contains one of the most used and respected Registry Cleaners on the market today. We encourage you to download and try it out, we know you’ll like the results!

CCleaner Updates All Your Software NEW

Outdated apps are a security risk. Old software can have vulnerabilities, which are quickly discovered and shared amongst cyber criminals. CCleaner updates your software automatically to close security holes before they can be found.

Faster Computer

Is your computer running slow? As it gets older it collects unused files and settings which take up hard drive space making it slower and slower. CCleaner cleans up these files and makes it faster instantly.

Safer Browsing

Advertisers and websites track your behavior online with cookies that stay on your computer. CCleaner erases your browser search history and cookies so any internet browsing you do stays confidential and your identity remains anonymous.

Fewer Errors & Crashes

Quicker Startup

Many programs run silently in the background when you start up your computer. CCleaner helps you get to work, or play faster by letting you disable unneeded programs.

How to clean the Windows 10 Registry

• In order to keep Windows 10 PCs running smooth, you have to do regular maintenance.
• One of the ways you can do this is to clean the Windows 10 registry with a third-party tool.
• If you want to learn how to clean registry Windows 10 manually use the regedit command.
• You should also create a restore point before starting to revert to the original state of the registry.

We all know that in order to keep our Windows 10 computers running smooth and fast, we have to do regular maintenance and clean the files that are left from old software installations.

Today we’re looking at cleaning the Windows 10 registry of these leftovers. We highly recommend you use a third-party tool if you want to clean the Windows 10 registry.

These tools have been created with this purpose in mind, and they evaluate the registry keys and only delete the ones which are no longer in use.

Also, keep in mind that some registry entries that are still in use can get damaged, and a third-party software can sometimes fix them, so there is one advantage of using this method.

There are two ways in which you can do this: with the default Windows 10 tools or with third-party software that is dedicated to cleaning the registry of your computer.

Before we begin explaining how to clean your Windows 10 registry, a word of advice: be very careful if you delete anything.

If you don’t know what you are doing, then there is a big possibility that your programs and the operating system will no longer work properly. Follow these guidelines at your own risk.

We recommend creating a Restore Point before beginning and also, create a backup of your registry as it is before you start deleting entries.

How do I clean the Windows 10 Registry?

1. Use a third-party registry cleaner

2. Cleaning the Windows 10 registry with Registry Editor

1. Press Windows Key + R and enter regedit.
   
2. Now press Enter or click OK.
   

Alternatively, you can just use the Search bar by doing the following:

1. Click the Search bar and enter regedit. You can also open the Search bar by using the Windows Key + S shortcut.
   
2. Select regedit from the list of results.
   

Before you clean your registry, it’s advised to back it up. Removing certain entries from the registry can cause various problems to appear, therefore be sure to back up your registry beforehand. To do that, you need to follow these steps:

1. Go to File > Export.
   
2. Now select All as Export range. Enter the desired file name, choose a safe location and click on Save.
   

If any issues occur after you modify your registry, you can simply run the file you just created in order to restore the registry to its original state.

The best way to do this is to search for registry entries of software that you have uninstalled. Using the left side navigation panel, go to HKEY_CURRENT_USER and then to Software.

Here, you will find a list of everything that is installed on your PC. Look for programs that you’ve uninstalled.

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.

Most registry cleaners are not a good thing to run on your PC, they can break your system just as easy as they can fix them.

Unless you know how the registry works & what the entries mean, using registry cleaner is of no use, if you want ‘clean up your registry’ (I am not sure why you would), if you have a problem post the problem and community members maybe able to assist you.

Use of registry cleaners is generally not supported, as they can cause more problems than a average user can deal with, they have been known to brick PC,s., worthless, kaput.

Registry cleaning programs are *all* snake oil. Cleaning of the registry isn’t needed and is dangerous. Leave the registry alone and don’t use any registry cleaner. Despite what many people think, and what vendors of registry cleaning software try to convince you of, having unused registry entries doesn’t really hurt you.

The risk of a serious problem caused by a registry cleaner erroneously removing an entry you need is far greater than any potential benefit it may have.

Let me point out that neither I nor anyone else who warns against the use of registry cleaners has ever said that they always cause problems. If they always caused problems, they would disappear from the market almost immediately. Many people have used a registry cleaner and never had a problem with it.

Rather, the problem with a registry cleaner is that it carries with it the substantial *risk* of having a problem. And since there is no benefit to using a registry cleaner, running that risk is a very bad bargain.

Using a registry cleaner is like, well, allowing a stranger onto your PC thru Remote Assistance (I know I would not), because you do not know what they are likely to do.

Registry Cleaners and System Optimizers are just not recommended as they tend to cause
more issues than they fix. And many of those are Snake-Oil. CCleaner is a fine program
for removing temp files which I use however I do not use the Registry Cleaner section.
Similarly I would not use the Registry Cleaner part of System Mechanic.

Hope this helps.

Don’t use it. I haven’t being using a very popular cleaning-program for some years now, just for testing, how this will go, because of the advices in here, and the computer runs like a charm. This very popular cleaner-program, only free up a few MB space on your harddisk, so it’s not worth to waste time with!

The only cleaner-program, I use, is Windows own Diskcleanup and Cleanup systemfiles, or in a command Prompt, runned like administrator, I just write cleanmgr, and mark everything except the Recycle Bin, which I want to run by my self.

But is there anything, we should’nt cleanup in Windows 10’s Cleanup systemfiles? Something, we should leave alone? (I only runs Windows 8.1 and 7, that’s why I ask. )
