How to download and clean Install Windows 10 20H2

Windows 10 20H2 is the next semi-annual update and is expected to come by the mid of November 2020. As of now, this features Chromium Edge (pre-installed), Eye-control and Narrator improvements, Calculator Graphing mode, and several fixes. The version 20H2 also includes features like – new icons, Family group setup, Optional Drivers, etc. Besides, the developers are constantly working to fix the bugs and issues that came along with version 20H1 like storage and other compatibility issues. 

Since Windows 10 20H2 is a minor update, there’s no need to download its ISO file separately. The company will simply push a cumulative update featuring all the recent updates, fixes, and improvements inside. However, in case you want to clean install Windows 10 version 2009, you may do so using the four methods elaborated in this guide. Let’s explore 4 different ways to clean install version 20H2 in detail –

Ways to Clean Install Windows 10 20H2 [2009]

To clean install Windows 10 version 20H2 on your PC, use any of the following methods – 

1. Windows Update 

In general, Microsoft pushes a notification regarding any new in-place upgrade via the Windows Update section. So, keep on checking if there’s any message or not. To do so, use the below steps – 

  • Jointly press Win+I to invoke the Windows Settings page.
  • Click Update & Security category. 
  • By default, this will take you to the Windows Update page.
  • Jump to the right pane and hit Check for Updates.  

Check For Updates

  • If there is any such update with name matching to Windows 10 version 20H2, hit Download.
  • This will then automatically download and install the cumulative update to your PC.
  • Finally, it prompts to Reboot Windows to make the changes effective from the next login. 

Note: Since the next upgrade is due in Nov 2020, you won’t receive any message until then. However, if you choose to become an insider, you may receive a cumulative patch that upgrades the OS to version 2009. 

2. Windows Update assistant

This is another great tool by Microsoft that lets upgrading a single operating system to the next major/minor update. We personally don’t recommend going for this unless you have top-notch net speed connectivity. Although the process seems to be a bit easier with fewer clicks, this often requires more than one download. In case, you are on a metered connection, this is definitely not a good choice for you. However, if you do have a sound internet connection, use the below steps-

  • Go to the Microsoft official website and hit Update now
  • The browser then prompts to save a setup file, hit “Save files”.
  • Now, go to the folder where you have downloaded the file and double-click on the same.
  • When the Assistant tool starts, hit Update now again.
  • Follow the on-screen instructions as the Windows assistant moves forward downloading the file.
  • When this completes installing Windows 10 version 20H2, this will prompt to “Restart Windows”.
  • Sign back into your computer and the Build OS info changes to Windows 10 version 2009.

Quick Note: Since the next semi-annual upgrade is due in Nov 2020, running this tool will not download version 20H2. Rather this will display a message – “Thank You for updating to the latest version of Windows 10”. Click Exit to come out of the current window.
