Microsoft is an American multinational corporation that develops, manufactures, licenses and supports a wide range of products and services related to computing.
Microsoft has a large FTP server at ftp.microsoft.com which contains a large amount of old files (quite a few are from the 90's) and hasn't been updated in a while. It has gone down a few times and might be worth archiving.
