How do I completely format my Windows?

If your PC is feeling cluttered, you're having technical issues or you're preparing to sell your computer, it may be time to factory reset Windows 10 or 11. That way, you can bring your PC back to the way it came when you took it out of the box.

This is a bit less powerful than the nuclear option: deleting the Windows partitions entirely and reinstalling from scratch. Both Windows 10 and Windows 11 have easy, built-in reset utilities that make a change to factory settings quite simple.

Factory resetting Windows 10 and 11 PCs involves very similar steps. In fact, the biggest differences have to do with the operating systems' differences in the Start menu and settings app. We have instructions for both versions of Windows below. Here's how to factory reset a Windows 10 or Windows 11 PC:

How to Factory Reset Windows 11

1. Click Settings. If you have it pinned in the Start menu, find it there. If not, you can find it by searching in Windows.

2. Scroll down to "Recovery" in the System menu. Settings defaults to the System menu in Windows 11, so just scroll and click.

3. Click "Reset PC" next to the "Reset this PC option."

4. Choose whether to keep your files or remove everything. The former option will keep the files but remove programs and any changes to settings. The latter gets rid of everything, but note that a very determined person with file recovery software might be able to restore your files.

5. Pick how to reinstall Windows 11. You can choose to download Windows from the internet, or to use a recovery copy that's already on your device.

6. Approve the settings and click "Next."

7. Click "Reset" one last time to confirm.

The PC will begin to reset. It will go to a screen that reads "Preparing to reset" along with the progress. The PC will reset multiple times and show a screen that reads "Resetting this PC" along with its progress percentage.

When the process finishes, Windows 11 will reinstall and your PC will start from the setup screen. You will have to pick some preferences and then log in with your Microsoft account (or use our trick for installing Windows 11 without a Microsoft account). Once that's done, you'll be back on the desktop and ready to use your PC again.

How to Factory Reset Windows 10

1. Click Settings. There's a gear icon in the Start menu, or you can find it in Windows search.

2. Click "Update & Security."

3. Select "Recovery" from the left side panel.

4. Click "Get Started" under the "Reset this PC" heading.

5. Choose whether to keep your files or remove everything. The former option will keep the files but remove programs and any changes to settings.

6.  Pick how to reinstall Windows 11. You can choose to download Windows from the internet, or to use a recovery copy that's already on your device.

7. Approve the settings and click "Next."

8. Click "Reset" one last time to confirm.

The PC will begin to reset. It will go to a screen that reads "Preparing to reset" along with the progress. The PC will reset multiple times and show a screen that reads "Resetting this PC" along with its progress percentage.

When the process finishes, Windows 10 will reinstall and Cortana will greet you (you may want to turn the sound down). You will have to pick some preferences and then create a Windows 10 profile or log in with your Microsoft account. Once that's done, you'll be back on the desktop.
