Best Registry Cleaner Software (Win XP,Vista,7 - 32 and 64)

Below are the key points that you should be looking when choosing a best registry cleaner software to clean windows registry.

Important registry entries that a registry cleaner must remove

Any Top registry cleaner software should have the ability to remove different types of invalid registry entries. Some registry cleaners clean only a few types of registry entries which are easier to detect and clean. This is a problem because the majority of registry errors and overall computer instability is actually caused by many other types of invalid registry entries. These registry entries are far more complex to track down and clean from registry and you can hardly get any optimization without cleaning them.

Registry entries contain the location of some important files on your PC. These files are used by OS and other programs in order to function properly. If your registry cleaner only removes the empty files or only few other types of invalid registry entries, your cleanings will no longer have an impact on your PC's performance.

Some of the important entries that a registry cleaner must clean are as follows:

• ActiveX Entries
• Windows Installer Entries
• Shared Dlls
• Application Path Entries in registry
• Help Files, Windows Fonts
• File Associations
• Windows Startup Programs
• Invalid File/Folder Paths in registry etc

Registry backup and restore

To stay safe you need to make sure that the registry cleaning tool that you choose provides a backup/restore feature. Nothing is perfect, and that includes registry cleaners as well. Even with the best registry cleaner software there are chances of having a problem when registry cleaner wrongly removes registry entry. It is not necessarily the fault of the registry cleaner and can be caused by a poorly-written program.

In such a situation, you need a way to restore your registry to it's prior state. Registry is the core database for windows playing with it can be tricky sometimes. Moreover the backup process should be automatic.

Registry Cleaner Compatibility with different versions of windows

One more important thing is the registry cleaner compatibility factor. There are different versions of Windows available e.g Windows XP, Windows Vista , Windows 7 and you also have 64 bit versions for XP, Vista and 7 as well. Registry entries are handled differently in different versions of windows. Serious problems can occur if you try to clean registry on certain windows version with a registry cleaner that is not truly compatible with that version. Any Top registry cleaner must clearly state the OS compatibility and it should cover a wider range on windows versions.
