ok sorry, you don't have the option to fix using windows update
so, you need to do an inplace upgrade
Download the ISO file to perform the procedure:
Access the link below and click "Download tool now" to download the Media Creation Tool.
https://www.microsoft.com/pl-pl/software-download/windows10
Run the tool and click "Accept" to accept the terms;
Select "Create installation media for another PC" and click "Next";
In the "Select language, architecture, and edition" step, leave the "Use the recommended options for this PC" box checked and click "Next";
In the "Choose which media to use" step, select "ISO file", click "Next", select where to save, and click "Save".
After downloading the ISO, do the following:
(If you have a third-party antivirus installed, temporarily disable it during the entire procedure.)
- Double-click the ISO file to run it.
- On the "Install Windows 10" screen, uncheck "I want to help make the installation of Windows better" and select "Change how Windows Setup download updates";
- On the next screen, select "Not right now" and click "Next";
- Accept the terms of use;
- At the "Ready to install" screen, select "Choose what to keep" and select what you want to keep.
- Click "Install" and wait for the procedure to finish. Your computer may restart several times.
