installation as a user

[Konfekt]

Replacing HCLM by HKCU let this batch script associate gvim with text file types as a user (without admin rights). Could the same be offered for mpv?

I stand corrected. Every key but those of the file extensions must be put into HKLM. However, since a user can add a new file association in the explorer, isn't there a way to achieve this as a user as well?
