Microsoft needs to provide "Windows Update" for sounds (and visual themes) rather than just offering them as pay-for "Plus" packs. The reason? No matter how good your musician is, ANY sound that's deployed on virtually every PC in the world and played over, and over, and over, and over again for the next five years (at least) is going to get sickeningly annoying. There are few sounds more annoying to me than that sickeningly happy sound of Windows booting up. Makes me want to chunder all over Bill Gates every time I hear someone in the office reboot.
