How to fix
Optimize your Windows Registry
on Windows

When I read online articles on how to boost my Windows performance, it always mentions taking care of Windows Registry. However, I'm not really sure what Windows Registry actually is and why it is so important to take care of it? Could someone please explain it to me?

Windows Registry is a database of all types of settings that are related to software and hardware present on any configuration of a personal computer. Without it, you would have to set up each individual program, as well as your icons, themes, and other settings manually each time you boot a computer. Evidently, the registry is an integral part of any Windows system.[ref en-2]

In the database, you can find all data related to hardware, OS software, and other programs as well as user settings (user accounts, installed software, documents on your computer and their types, etc.). Programs access the registry numerous times every second, and new entries are created when new software or hardware is installed on your computer.

As a general rule, users should not tamper with the registry for no good reason, as incorrect modifications might result in errors, crashes, or complete Windows OS collapse, resulting in a need to reinstall it all together. While this might seem like a minor inconvenience, this unfortunate event could result in personal file loss - something that nobody would like to deal with.

Unfortunately, each of Windows databases can sometimes encounter bugs[ref en-3] due to which users might start experiencing various issues, including errors like 0x80070002, 1073741819, 0xe06d7363, or many others. In the worst-case scenario, registry errors can cause a Blue Screen of Death,[ref en-1] which might also prompt users to reinstall the operating system.

These problems typically arise when applications are not removed correctly or when the code is buggy. The problem is that, once an app is removed from the system, Windows registry entries created by it previously remain intact. If enough apps are installed and uninstalled regularly, these bits of data can accumulate and hinder normal computer performance - this is one of the reasons to optimize Windows registry.

Another reason to intervene with the Windows registry is due to malware infections. Malicious software, identically to genuine program, would open the Windows registry in order to modify and create new registry keys.[ref en-2] The database is often used for persistence mechanisms, as it allows the malware to be booted each time when the computer is booted. For that reason, you should fix the Windows registry each time after a virus infection.

Clean Windows Registry manually

If you a do-it-yourself kind of user, you can clean Windows Registry by yourself. However, we would highly advise you to assess your competence because registry errors may result in serious problems that will crash your system or destroy your information. Therefore, make manual adjustments of Windows Registry at your own risk. 

The best way to ensure that your computer system would not collapse, it is best to prepare a backup of your registry first. Here's how to do it:

• Type in regedit in Windows search
• Right-click the Registry Editor result and select Run as administrator
• When User Account Control window shows up, click Yes
• Click File > Export
• Select the location where you would like to store the backup of your Registry
• Ensure Export range is set to All and then click Save

  

If you would like to eliminate registry entries related to a particular program, you should perform the following actions:

• Open Windows Registry once again as explained above
• Go to Edit > Find...
• Type in the name of the program you are looking for and press Find next
