Dawnguard, Hearthfire, Dragonborn is how LOOT would sort the dlc. Windows 10 is later than Vista so i would guess it is compatible, theres the zip file but i just used the installer when i download it (LOOT.Installer.exe) i think you would need 7-Zip to open up the 7z file (but i already have 7-Zip it so can't really test it).
