Bug: Mixed/wrong language translations in context menu

[SirePi]

Description

Opening the context menu on a system with multiple languages installed causes some of the commands to appear in a different language. See attached image for example

My case could be even more specific as I am currently an English system and UI language, Italian locale for dates and numbers, and English and Traditional Chinese keyboards layouts installed. The "Notepad", "File Locksmith" and "PowerRenamer" entries are localized in Traditional Chinese instead of the expected English. Default context menu to show that they are actually properly shown in Windows

Steps To Reproduce

1. Have a system with multiple languages installed and possibly PowerToys or Notepad++ installed
2. Open the context menu for any file

Requirements

Show the correct language for all menu entries

Well, I can work on this issue maybe

I think this is an issue with Windows.

[Sanidhyafeaturist]

@Lamparter I think that there should be modification on code like system is using multiple languages, the app should fetch the display language from the user's settings and apply it consistently

The extension label is pulled from Windows but in theory, it should match File Explorer. It's worth looking into this to see if we can pull a different value.

I wonder what the result of GetThreadUILanguage.
Looks like SetThreadUILanguage changes .rc file's resource system switch.

@SirePi Is this still an issue on v4.0.11 https://files.community/download

Btw, just casually: how can this bug's presence be tested in a practical way?

Is the specific locale / language pack necessary? If someone's got a link to step-by-step, testing, please -
just refer me to the test docs :)
