As I mentioned in my introduction, only use this method if you’re installing Windows 10 update 21H2 before Microsoft releases the next update (around November 2022).

If Microsoft has released another update, when you use the steps below, you’ll be installing the latest Windows 10 update. To install Windows 10 21H2 (after November 2022), use the second method in this guide. Follow the steps below to install the latest Windows 10 update. Before you install the latest Windows 10 update, you need to check that you have enough space in your Windows 10 install drive. Use the first sub-section below to check the space on your PC’s OS drive.
