Windows Update

The best and safest way to get this update is to update your existing Windows 10 from the settings panel. If you already have updated the previous version 20H2 or 20H1, the update would be small in size. While the users having Windows 10 v1909, 1903, and earlier versions should not prefer this method.

Official Tools

You can always download the latest Windows 10 ISO using WMC (Windows Media Creation Tool) or Windows Update Assistant tool. Microsoft itself officially releases both.

No doubt this is the most secure method to download and automatically install the latest version of Windows 10, but it has disadvantages, such as:

  • If power fails or the computer crashes, and you downloaded 99%, you will lose all progress and start from zero.
  • It is a background download, and you can not have the ISO file for future use.
  • The download speed might be slower as the program uses its own background downloader.

Third-Party Websites

Windows OS is the soul of your computer. Suppose someone has modified and uploaded it on their own website or third-party server. In that case, none of your antivirus or security suite has to save you from unrestricted and unauthorized access. Beware of such downloads.

Web browser tricks

You can trick Microsoft servers into showing you the Windows 10 ISO download links. You may use Chrome, Firefox or any web browser. This is a kind of valid method but not easy for everyone.

Windows 10 ISO download tools

Though a third-party tool, if any tool takes you to official Microsoft servers and then helps you download the original Windows 10 ISO from original Microsoft servers, this is also a safe and valid method to get the latest full ISO of Windows 10 from Microsoft.
