Hello,
I tied my Desktop to a newly created OneDrive. Then I realized that some programs can't work with my files on Desktop, so I manually removed the Desktop form OneDrive folder by dragging it from there. The problem was still there and I realized that the Desktop folder got translated into OS default language, in this case Russian. Instead of "C:\Users\Username\Desktop" it is now "C:\Users\Username\Рабочий стол".
I can't fix the problem by simply renaming it in File Explorer, because it retains it Russian path name, instead of being named "Desktop". I tried to rename it through cmd, but "Desktop" just turns into a regular blanc file icon with no name that can't be opened and File Explorer can't open the files on Desktop, that is apparently still called "Рабочий стол", a folder that didn't exist. After I rename it back to Russian name, it fixes itself.
I want English "Desktop" back, because some of my progrmas can't read Cyrillic in file paths.
