"Refresh Windows" tool is a new official program released by Microsoft to help users in performing clean installation of Windows 10 operating system. This tool will reset Windows 10 and will remove any extra app installed by the user or came pre-installed by the manufacturer in the PC. After resetting, it'll install a clean copy of Windows 10. So you'll get a fresh clean installation of Windows 10 in your computer.
If you remember when Microsoft released Windows 8 and Windows 8.1 operating systems, both the OS came with 2 new and very useful features: Reset PC and Refresh PC.
"Reset PC" feature in Windows 8/8.1 works like "Reset to default" or "Restore factory settings" options present in mobiles, tablets, etc. It formats the drive and clean installs Windows OS. It doesn't keep any personalized setting, documents, installed apps, etc.
"Refresh PC" feature in Windows 8/8.1 repairs Windows OS. It doesn't remove everything from the PC. It reinstalls Windows but keeps your personal files, settings and apps.
With the release of Windows 10, Microsoft removed "Refresh PC" feature from the OS. Windows 10 comes with "Reset this PC" feature only which can be considered as a combination of previous "Refresh PC" and "Reset PC" features.
Now to bring the standalone "Refresh PC" feature back to Windows 10, Microsoft has released this new "Refresh Windows" tool which performs clean installation of Windows 10 in your computer and helps you in keeping your personal files in your computer.
At the moment this tool has been released for testing purposes and works on Windows 10 Insider Preview builds only. You must be using Windows 10 Insider Preview build 14342 or later to be able to use this tool. It happens because Microsoft has released this tool in preparation for the upcoming Windows 10 Anniversary Update build which will be released next month if everything goes per Microsoft's plan.
This tool downloads the latest available build of Windows 10 from Microsoft servers, so you'll need a working Internet connection to download Windows 10 setup ISO file of about 3GB in size.
This tool will allow you to keep personal documents but it'll remove all 3rd party software and store apps (modern or metro apps) which do not come bundled with Windows by default. It'll remove all apps installed by the user or installed by the computer manufacturer (OEM) company.
After performing clean install of Windows 10 using this tool, you'll need to install all 3rd party software, apps and drivers manually.
At the moment only 3 languages are supported by this tool: English (EN-US), Chinese (ZH-CN) and Japanese (JA-JP).
