How to Manually Install Windows 10 20H2 Update from Microsoft Update Catalog

How To Manually Install Windows 10 20H2 Update From Microsoft Update Catalog

As I said in my introduction, follow the steps in this first section if you want to install Windows 10 20H2. However, if you want to manually install the latest Windows 10 update, use the steps in the section instead.

To manually install Windows 10 20H2, you need to download the update from the Microsoft Update Catalog site. However, you need to download the update for your PC’s processor architecture.

 

So, in the first sub-section of this section, I have detailed the steps to find the processor architecture of your Windows 10 PC. Once you have determined your PC’s processor architecture, use the steps in the second sub-section to download and install Windows 10 20H2 update.

Check Your Windows 10 PC’s Processor Architecture

  1. Search cmd using your Windows 10 search. Then, from the search results, open Command Prompt.

  1. When Command Prompt opens, type the command below and press enter key on your keyboard.

The above command displays your PC’s architecture. From the result of the command (see the screenshot below), that PC’s architecture is x64 bits (x64-based PC).

Note this information as you’ll need it in the next sub-section of this section.

  1. When you start installing the update, the installer will check for existing updates on the computer. If you have not installed the update previously, the installer will install Windows 10 20H2 Update.

If you receive an error message, it may be that you downloaded the incorrect update for your PC’s architecture. On the other hand, the installer may also display a message that the update has already been installed on your PC. See the second screenshot below. If you receive this message, your only option is to install the latest Windows 10 update. See the second section of this guide for the steps to do this.
