Seemingly day-by-day, vendors are withdrawing support for XP. Want to run the latest version of Microsoft Office on it? You can't. Want to install Apple iCloud to sync your contacts and calendar? Sorry. Want to use Google Chrome, so you can access today's websites? Nope. Even Dropbox, who have an exemplary record in supporting old platforms, plugged the plug on the XP version in the Summer. Windows XP really is dead in the water.
Yet, some organisations continue to use it. For instance, a recent report states that 90% of England's NHS Trusts continue to use Windows XP (see www.theregister.co.uk/2016/12/08/windows_xp_nhs_still/ ). On the face of, that sounds bad, but it is worth noting that although Microsoft does not support XP for Joe Public, enterprises and public service bodies are able to negotiate (relatively expensive) extended support contracts. This continues to make it viable for some applications, although not necessarily for general purpose computing.
Windows XP - the operating system that refuses to die!
