After some software in the computer is opened, some menu words become boxes. What should I do?

Take Windows 10 as an example:

1. Right-click the desktop.

2. Select a new text document.

3. Open the text and copy the following paragraph:

Windows registry editor version 5.00

[HKEY _ LOCAL _ MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ current version \ Fonts]

Microsoft yahei & Microsoft yahei UI (TrueType)"="simsun.ttc "

[HKEY _ LOCAL _ MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ current version \ font substitutes]

"Microsoft yahei" = "simsun"

"Microsoft yahei UI"="SimSun"

Rename the file, change the suffix to reg, and then open it.
