I don't think importing would solve my problem. because of all the metadata (album's year, lyrics, etc...) I would have to add manually myself. I believe there's an easy way to do all this maybe I'm not explaining myself correctly. I believe I'l try this:
1) I'll copy the MusicBeeLibrary.mbl file to an empty usb drive
2) I'll fomat my hard drive deleting everything that's on it
3) I'll install Windows 10
4) I'll install MusicBee
5) I'll copy the MusicBeeLibrary.mbl file from the usbdrive and paste on the new MusicBee directory just created
6) I'll open MusicBee and hope for the best
