Instead of a upgrade or after a upgrade?

Then you've come to the right place, because here...

...I will show you step by step how to download and install or reinstall Windows 10 by creating and using an installation media such as a USB flash drive or DVD (ISO).

Good news! You don't need to upgrade first, because since November 2015 you can also use Windows 7, 8 and 8.1 product keys to activate Windows 10 on your PC.

But first:

Why a Clean Install of Windows 10?

There are people who encountered some problems after upgrading Windows 7, 8 or 8.1 to Windows 10.

Problems like:

And other problems.

The Windows 10 upgrade drags programs, settings, drivers, and files from your previous Windows system to Windows 10 and this might cause problems.

The best solution to solve many problems, is to download and reinstall Windows 10. This is called a "".

I think that it's always better to do a clean install of Windows even if you don't experience any problems.

Microsoft allows you to download Windows 10 from their website for free. And since November 2015 you can also activate Windows 10 with a Windows 7, 8 and 8.1 product key. This means that you don't have to upgrade first before doing a clean install.

You need to upgrade to Windows 10 first, because when you upgrade, the installer confirms that your Windows is genuine (legal), then it activates your PC for Windows 10 and registers your computer's hardware with Microsoft. This way you can always uninstall and reinstall Windows 10 on your PC (if necessary).

If you don't upgrade first, the registration of your PC's hardware will never happen.

You don't get a Windows 10 product key. Your PC's hardware is your (kind of) product key.

So it's important to upgrade to Windows 10 before you can perform a clean install.

How to Clean Install Windows 10

To download and do a clean install of Windows 10, you need a free tool called "Media Creation Tool". It's a tool created by Microsoft and can be downloaded at the official Microsoft website.

This tool allows you to download the correct version and edition of Windows 10 (home or pro and 32-bit or 64-bit) and create a installation disc or drive that you can use to install Windows 10 on your computer.

You can download the Windows 10 media creation tool . Just click on "Download tool now" (located at the bottom).

1 If you want to create a installation disc, then insert the disc into the CD/DVD drive of your computer and if you want to create a installation drive, then connect the USB drive to your computer (USB must have at least 3GB of memory).

2 Open "Media Creation Tool".

3 Select "Create installation media for another PC" and click on "Next".

4 Select from one of the available options. I recommend "Use recommended options for this PC".

Important! Like I said in the "Before you begin" chapter on this page, you should download the right version of Windows 10, otherwise it wont work and you can start all over again.

7 Click on "Next".

8 Select the disc or drive and click on "Next".

The "Media Creation Tool" will first download Windows 10 and then create the installation media.

This may take a while. It depends on your internet speed.

9 When the installation disc or drive is ready, you need to restart your computer with the installation USB drive connected or the DVD inside and boot from that device.

If the Bios of your system is set to boot from a CD/DVD or USB drive, then you will see "Press any key to boot from DVD (or USB)".

If you don't see this message, then you will need to press the correct key to open the boot options. On many computers it's the "F12" key, but it really depends on your computer.

Most common keys to open boot options are F9 on HP, F10 on Sony, F11 on MSI, F12 on Dell, Lenova and Acer, and Esc on ASUS.

10 Press within 5 seconds on any key to boot from a DVD or USB.

11 Click on "Install Now" when the Windows installer starts.

12 Windows will now ask for a product key:

If you didn't upgrade before, then you can enter your Windows 7, 8 or 8.1 product key and click on the "Next" button.


If you already upgraded before, then you can click on the "Skip" button, because your PC's hardware is already registered with Microsoft and it will activate by itself.


If you do have a Windows 10 product key, then you can enter it here and then click on the "Next" button.

13 Follow the setup process steps (easy) until you reach the "Which type of installation do you want?" screen.

14 Click on "Custom: Install Windows only (advanced)".

15 Select the hard drive you want to install Windows 10 on.

If you don't know which drive or partition to choose, then look for the largest one, or the one that says "Primary".

16 Click the "Format" button.

If the "Format" button is grayed out, click on "Delete", and then click on "New".

17 Click on "Next" to install Windows on that drive.

18 Allow the installation wizard to guide you through the rest of the process.

Once Windows 10 is installed, you can install your favorite programs and apps and enjoy a fresh and clean Windows 10.

Tip! Create a system image backup after installing Windows 10 and your programs. A system image is a backup of of Windows, programs, settings and files. You can use this system image to restore Windows and programs when there is something wrong like a virus or malware, system or software that stops working, or other problems.
