The computer also comes set up with the latest VMware Fusion 8 installed, with full support for the very latest version of OS X (10.11 El Capitan), so you can have both OS X and Windows on screen at one time. See the video above - you will need a desktop browser, it will not play on a phone or tablet, or see it here:

You can have Windows installed natively as well as through VMware for an additional fee of £75 so you can boot directly into Windows, and run only Windows. This is useful for guaranteed compatibility with programs like Sage or Quickbooks, Windows gaming and the easy installation and upkeep of older Windows software. You still get the ease of use of VMware on top of the native install. All softwares come with their license keys and discs where appropriate. You can choose to have Windows on disc or ISO (digital format). Please note that the native Windows 7 installation is no longer available - if you want a native install it has to be Windows 8.1 or Windows 10. You can still have Windows 7 or XP virtually (as in the video). Windows 10 is now available as an upgrade for £60, and anyone who purchases Windows 7 or Windows 8.1 can upgrade to Windows 10 at any time until August 2016. All upgrades after Windows 10 will be delivered as updates to the current version, so you won't have to worry about upgrading ever again.
