How to Update to the Latest Windows 10 (20H1) Version via the Windows 10 Update Assistant

We show you how to update to the latest version of Windows 10 with the Windows 10 Upgrade Assistant, cutting out individual cumulative update downloads.


For the most part, an update to the latest version build is a simple process via the OS' built-in features. However, this path quickly becomes a nuisance if you're on an earlier build, forcing you to apply numerous patches individually. In such cases, it's best to utilize the Windows 10 Update/Upgrade Assistant to get the latest version (Windows 10 20H1).

First, though, you may want to check what version your OS is currently running. It could be that automatically upgraded you to without you noticing. To do so, open System Information from the Start Menu. Under the “Version” tab, check your build. If you're on the Windows 10 May 2020 update, it will read Windows 10 2004, Windows 10 20H1, or Build 19041.

If you're still on an older version, that's quite normal. The Windows 10 May 2020 update is a staggered one, meaning Microsoft is rolling it in increments. We're going to show you how to bypass this with the Windows 10 Upgrade Assistant and skip smaller time-consuming updates in the meantime.
