What should I do if the Windows 10 official version of the font is garbled as a square?

Happy to upgrade Win10, but open a Korean song, the lyrics are full of screen squares, very unpleasant. This article brings you the right way to solve this problem. (This article is written in Korean, but this method is applicable to multiple languages.)
1. Open Windows 10's "Settings" panel

2. In the search box on the right side of "Settings" Search for <;optional features", then click “add optional features"

3, scroll down the list, find the "Korean supplementary font" in the middle. Click once, and there is an additional "install" button, and then click the "Install" button.

4. After clicking, you will find it disappears. At this time, click the back button in the upper left corner to see the progress prompt as shown below. (The screenshot is an example) You can see the progress bar.

5. When the progress bar is full, it indicates that the function is installed. At this time we can see the font just installed here.

6, after that, completely exit the software that just showed abnormality (some softwares need to right click in the lower right corner of the tray area to exit, as shown in Figure 1), and then re-open, you can see the full Korean support. .



Note: This method works for many languages, not only in Korean.
