Major, major chaos- especially for their business clients. Microsoft goes out of their way to make sure there is still support for business LOB apps running Delphi and MFC. Just look at their long term support. Windows XP had like 15 years of support. "From the ground up" might be a good idea, but tons of existing software is actually built around former bugs in the OS-- so writing a new OS "the right way" would actually break the apps of their target demographic (business clients.)
