I remember the first time working with a Windows 2012 R2 server.
Of some reason I couldn't open Windows Powershell as admin and asked another Dev what to do. His response? Try restarting the server.
Can you imagine the look on my face if I told you I only worked on Linux until that point. How can you seriously make a server OS that needs restarting at all? Is it just me or is that just fucking stupid?
