Hi all, since this is my first post.

In these systems if you assign an application to the extensions are in the key "HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ FileExts \. Xxx \" creates a subkey "UserChoice" with "ProgId" eg for. txt after WordPad will assign a textfile.

Liberkey with "Replace the current actions for These type of files" is checked or not, only modifies the entries in "HKEY_CURRENT_USER \ Software \ Classes \. Xxx", eg for. txt modify the key "textfile" or "textfile_nomade".

You could modify the "KEY Assoc Files" that for Vista, win7 first remove (backup) "UserChoice" or do all the assignments to "UserChoice".
