Desktop Operating System

So, what do you folks run as your main desktop O/S? We're Windows 7 Pro across the 5000 PC's but have to seriously consider what the plans are in 4 yrs when it goes out of extended support. At present just doing ball park figures, a shift to Win X, Office 2xxx, Exchange, AD/Server etc would be over £1m in enterprise agreements annually........

Anyone done a mass migration to Linux?

Should have said, 5k PC's/laptops with 8k users. O365 isn't currently suitable for application in public sector at present, or suitable for the current way we work.
