Being an employee who relies on computers, this kind of practice is not economical and practical. They kept on pressuring businesses and institutions to comply to their standards. Why put 6 year old computers to halt if they still could function for my daily needs? Why fix if it ain't broken, right?

I've ditched Windows for 4 years already, and use Windows 10 only in office, due to task requirements. And all I can say is, [strawberry] WINDOWS 10. (Windows 7 still rocks)
EDIT: For those who want to explore GNU/Linux, try Zorin OS or Linux Mint.
