All Windows system files, folders and built-in applications and tools are always named in English and you as the user should not change them to your language.

To give me more localized experience, Windows uses links in Finnish to point to files, folders, apps and tools.

As I have relocated the main user profile folder to drive E:, when I open that drive it shows me folder Käyttäjät (Users). However, Ohjelmatiedostot and Käyttäjät are not real folders but instead localized links pointing the real folders which due system integrity must always have their original English names, Program Files and Users in this case. This can be clearly seen for instance when comparing the File Explorer view and Command Prompt view:

Check yourself: Using File Explorer, go to your Brugere (Users in Danish) folder. You can see the localized name and path shown in addressbar as here using my Finnish Windows as an example:
Now click within the addressbar to see the real, absolute folder name and path and you will notice that although I think I am in Käyttäjät folder, I am in fact in Users folder instead:
This applies to all system folders. Another example: I go to a user folder called Tiedostot (Finnish for Documents). Explorer shows the localized path and folder (link) name:
Clicking the addressbar I can see the absolute path and folder name instead:
One example using an app. In All Apps view I search for Laskin (Finnish for Calculator). I can search it using its localized Finnish name Laskin because Windows has created a localized link to Calculator, or using its real English name Calculator:
Checking the properties of Laskin clearly shows that it is just a link in Finnish pointing to an application with the original application name Calc.exe, the name this app de facto has in any language version of Windows:
The same with all built-in Windows apps, for instance my Finnish Windows shows an app called Muistio but searching the computer there is no such app; instead Muistio is a localized Finnish link referring to an app with English name Notepad. Again, in all apps view I can search this app using either its localized link name Muistio or original English name Notepad
Windows system files, folders, apps and tools are always named in English. If Windows is installed using any other language than English, the system creates localized links to all these files, folders, apps and tools so the user could see everything in his / her own language.
When using File Explorer you will by default see the folder, app and tool names in your language, in your case in Danish and in my case in Finnish. However these are only links to allow you to have a more completely localized Windows experience, the real folders and apps have English names.
As a user you should never change these system names. Your File Explorer will and should show Programme link which points to Program Files folder, as well as the Brugere link which points to Users folder and so on. This is how Windows functions by design, it is not an issue but instead a system created to give you more localized Windows experience.
