Formatting the computer can be the solution to many problems. For example, if you have upgraded from Windows 10 to Windows 11, you may be experiencing performance issues or frequent errors. Something similar happens if you have the habit of installing and uninstalling many programs. In that case, the best way to clean your computer completely is to reset it. There are two procedures to do so that you should know and we will talk about them in this guide.

How to format a computer from the setup application

We start by talking about the simplest method of formatting your computer. This is located in the settings application, easily found in the Start menu. You can also use the combination Windows + I to access the options.

In the pop-up window, you will see two options. Although there is a way to restore the computer while keeping the existing files, the most recommended way is to Remove everything. By choosing it, you will be able to apply a deeper cleaning to the system.

In the next step, choose whether you want to reinstall Windows 11 from the cloud or locally. The first option lets you get the latest available version published by Microsoft, although with a slower process due to the implicit download. On the other hand, you have the Local reinstall option, which is faster because it does not require downloading the entire operating system again. The truth is that it will not matter too much which one you choose, as in both cases, the system will be completely reset and all files will be deleted.
