Do we have to sell the computer? Or do we just want to restore Windows 10 to a clean and efficient state by erasing everything? Here’s how to perform a clean installation of the operating system.
The premise: It is recommended, if you have not already done so, to save your data to an external disk before performing a clean installation.
Situations where it is useful to do a clean installation
The situations and circumstances in which it is useful to perform a clean installation are:
- selling the computer to third parties
- malware infection rooted in the system
- generalized operating system issues that cannot be fixed with a re-installation
First method: we use operating system tools
Obviously the first method is to use what Windows 10 provides us as recovery tools, in fact from Settings > Update and Security > Recovery > we choose Reset

Now choose Remove All and then open Settings to turn on Data Deletion.

Second method: We use a tool provided by Microsoft
Another method, in case there are problems with the first, is to use a reset tool provided by Microsoft.
This tool (downloadable from the end of the article) allows you to re-initialize the system by deleting the data, just select Nothing under the “Choose what you want to keep” item
