Cons
Con Most software is closed source, including the operating system itself
Con Weak default terminal
The standard terminal lacks basic features that Linux and OSX has. Alternatives to the default terminal for Window can be found here.
Con Lacks package management
It is not easy to install/keep current development packages that developers need and use.
Con There are some privacy issues
By definition, it's spyware. Pre-compromised OS.
Con Scanning for viruses makes builds slow
Compiling a project means reading and writing a lot of files. Even fast anti-virus software slows down the build time (which is almost always too long).
Con Maintenance is time-consuming
Previous versions needed to be formatted ever 6 months to maintain performance.
Con Embarrassing to give talks
On conferences or in user groups the audience laugh at speakers presenting their talk on a Windows machine.
