Where did the Russian language disappear in Windows 10 applications?

Question

Windows

Today, after turning on the computer, I discovered that many Windows 10 applications (from the store) were in English. Interface language is Russian, location is Russia. How can I return the Russian language to applications?

Answer 1

Managed to solve the problem myself. Control Panel -- Language, clock and region -- Language. In the list of languages, Russian has risen to the first place (The language at the top of the list will be considered the main one). All applications are back in Russian.
