I wonder if pre-acquisition Skype was one of the hardest software the Windows team had to deal with. For example, at one point they used SYSENTER directly to make system calls!


Do you have a source for this? I enjoy reading about horrible software.


For SYSENTER: https://www.virtualbox.org/ticket/1710

Another example: https://www.pagetable.com/?p=27

This is just what is public.


Source? Skype was always quite cross platform imho.
