Refresh Windows

Refresh Windows is a straightforward and useful, Microsoft-vetted piece of software that makes it possible to upgrade to the latest Windows version.
As an added bonus, it provides you with the possibility of either erasing all the apps and files installed or that came pre-installed on your computer or of only keeping your personal files untouched, as is the case with a typical Windows update

A few details that you should know before you get started

Before you get too excited, you should be aware of the fact that, at least for now, this tool only works with the latest Windows 10 Insider Preview (release build 14342) or later.
Furthermore, this app will remove all applications that are not installed by default on Windows and other Microsoft programs such as Office, all OEM apps and even some drivers. This said, after the clean installation is completed, you might want to head over to the Control Panel, System and Security and perform a basic Windows Update to get the latest drivers.
Therefore, it is almost needless to say that backing up any data you want to keep is always a good idea, even more so in this case.

Perform a clean installation of Windows with just a few mouse clicks

With these worthwhile details on the table, you can start performing a clean install of your Windows. The tool basically guides you through the whole process with the help of a streamlined wizard.
Simply launch it via its executable, review and accept the license terms, choose one of the two offered options, namely the self-explanatory 'Keep personal files only' or 'Nothing' - in which case your settings, apps and all files will be deleted. Subsequently, you are required to click the 'Install' button to begin the actual process.
From this point forward, the app takes care of everything in a very convenient manner: the latest version of Windows 10 Insider Preview will be downloaded and then installed automatically, followed by a system restart.

Give your Windows 10 PC a clean start with the help of this lightweight and efficient tool

All in all, Refresh Windows is a uber-useful application that enables you to quickly clean-install the latest version of Windows 10 Insider Preview on your computer and get rid of some pre-installed apps you do not need, with the least amount of effort on your behalf.
