Stupid situation with .lnk on Windows?

Question

Windows

.lnk is a shortcut file in Windows 7. In some veiled way, I managed to get Windows to open files with this extension with Total Commander. The question is how to nullify labels for their true purpose? What should I change the association of these files to?
PS. One of the dumbest reasons to reinstall the system

Answer 1

KEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.lnk

Answer 5

Also look in HKCU, it should be like this:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.lnk]
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.lnk\OpenWithList]
[HKEY_CURRENT_USER\ Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.lnk\OpenWithProgids]
