Windows 10 was released yesterday, and it may have already be downloading on your computer.

As we have told you before, Microsoft will allow unlimited clean installs of Windows 10. But there is one requirement you must fulfill. You must upgrade your existing genuine Windows 7 or 8 or 8.1 to Windows 10. Once you have done that, you will be able to clean install Windows 10, any number of times.

The reason is this, Windows 10 takes a hardware fingerprint pf your device, and stores it in your Microsoft Account. By doing so, you will not have to enter a product key when you clean install Windows 10 later, and you will continue to get Windows Updates for free for the lifetime of the device.

Now that we have got the issue out of the way, let us see how you can clean install Windows 10.

Important: Backup all of your data to an external drive or a spare HDD before proceeding. Your Windows 7 or 8 key will not be accepted by Windows 10, the only way to validate it the first time, is by directly upgrading from your current operating system.

Disclaimer: This guide assumes you have upgraded from a genuine Windows (7 or 8) to Windows 10 before you try either of the following methods.

There are two methods to clean install Windows 10.

Method 1 – Reset Windows

1. Click on Start and select “Settings”.

2. Now click and “Update and Security”

3. Select “Recovery”.

The second option “Remove Everything”  deletes everything on the PC, including apps, folders, etc. Choose this option, if you wish to reset your PC.

Method 2 – Normal Clean Install

1. Download the Media Creation Tool from Microsoft, to create a bootable USB or DVD to upgrade.

2. Run the app, and select the second option, which says “Create installation media for another PC”. (This will help you  install Windows 10 on all of your PCs)

4. Choose the media you wish to use. Either a USB Flash Drive (pen drive) or a DVD.

5. Windows 10 will be downloaded to your external media.

6. Once it has finished downloading, you can shut down the computer. Start up the PC and immediately go to the BIOS settings and enable your external media as the first boot device. Save the changes, and your PC should restart, and boot to the external media.

7. Select the second option, Custom: Install Windows Only, and format your C: drive and then follow the on-screen instructions, install a fresh copy of Windows 10.

Once the installation is complete, and the PC has booted into Windows, you will find that it is already activated.

You can also use the Media Creation Tool to directly upgrade your Windows 7, 8 or 8.1 PC to Windows 10.
