I think this should work:
- right click on any DXF file
- go to open with... in context menu
- there should be something like select default application
- this will open a new window with some default applications
- if LibreCAD isn't listed, you have to search for it, I think there should be a search or browse button
- when you have found LibreCAD.exe, usually in C:\Program files\LibreCAD, click on it and then the open button
- now select LibreCAD from default applications and check the option always use this application before you click ok

I have no English Vista available, so the buttons and options may not exactly match with my naming, but I think you can handle this.
