6 Best Free Portable Registry Cleaner Software For Windows

Here is a list of best free portable registry cleaner software for Windows. These portable registry cleaners work similar to standard registry cleaner software that let you clean various types of registry data. Although, you can use these cleaners without installation as they are portable. Plus, you can also directly use them from a portable storage device to clean system registry.

Through most of these software, you can easily find and clean registry data of various types, such as MUI Cache, ActiveX, Class, Applications, and more. The good thing about these cleaners is that they let you manually select the registry files before cleaning them. However, if you want to clean all the registry data at once, then you can also do that.

The advantage of registry defrag is its ability to improve the system performance without cleaning the registry. Additionally, the process to clean registry is not that difficult in these software. To further help you out, I have included the steps to clean registry in each software.

Through some portable registry cleaners, you can also clean web browsers data such as History, Sessions, Cookies, etc. Plus, some also offer multiple additional features like System Tuneup, Startup Manager, Program Uninstaller, and more. Go through the list to know more about these software.
