Sorry for the delay in reply. I've been offline.
Thanks for the screenshots.

Don't worry about the language. I can translate screenshots. And I love seeing screenshots in other languages.

Your Windows 10 is on an old version (20H2). The latest version is 22H2.

I suggest you perform an In-place Upgrade to the latest version (22H2) using a Windows ISO file.
Don't worry. It's a simple procedure, and you have the option to keep files, settings, and apps. Therefore, all your data is kept.
(If you have a third-party antivirus installed, temporarily disable it during the entire procedure.)

Download the ISO file to perform the procedure:

1. Access the link below and click "Download tool now" to download the Media Creation Tool.
   https://www.microsoft.com/software-download/win...
2. Run the tool and click "Accept" to accept the terms;
3. Select "Create installation media (USB flash drive, DVD, or ISO file) for another PC" and click "Next";
4. In the "Select language, architecture, and edition" step, leave the "Use the recommended options for this PC" box checked and click "Next";
5. 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:

1. Double-click the ISO file to run it.
   (After running the ISO, you may need to double-click the "Setup" file to start the procedure.)
2. 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";
3. On the next screen, select "Not right now" and click "Next";
4. Accept the terms of use;
5. At the "Ready to install" screen, select "Choose what to keep" and select what you want to keep.
   (In this step, select "Keep personal files and apps" so that all your data is kept.)
6. Click "Install" and wait for the procedure to finish. Your computer may restart several times.

At the end of the procedure, your Windows 10 will be in the latest version (22H2), and some updates will already be installed. But check Windows Update to be sure.
