Windows 7 Extended Security Updates will double in price each year

For organizations already subscribing to Windows Enterprise, the first year of updates will cost an additional $25 per device. This doubles to $50 for the second year and $100 for the third year.

For companies sticking with Windows 7 Pro instead of subscribing to Windows Enterprise, the first year will cost $50 per device and will double each subsequent year to $100 and then $200.
