Below the normal view of PPT, the left thumbnail does not display the serial number, and the menu options in PPT do not display the text completely. What happened? Solve!
After repeated attempts, we finally found the cause of the problem and the solution.
The reason is that the operating system with this problem lacks the font file "Microsoft Yahe General" MSYH. TTC
Solution: copy this file MSYH. TTC is on other computers. Putting it in the C:\windows\Fonts file can solve this problem.
