In the days of Windows XP I made a collection of classical soundbytes (with help of Nero Wave Editor) to change the standard sounds which come with Windows. So when I empty the dustbin, a lot of drums are heard. With the arrival of new mail another minute piece of instrumental music sounds. Etcetera. The soundbites are taken from Mussorgsky & Tchaikovsky operas. Each of them is small, but the total adds up to about 26 Mb. As 'showpiece' I add the soundbite with which my Windows starts (taken from Tchaikovsky's Pique Dame). If somebody's interested in converting Windows into classical, just let me know!
