The trust are talking crap
None of this adds up to a problem with Microsoft. It all adds up to a problem with management not having a clue what they are doing. For a start, despite comments from the usual Mac and Linux retards above, Operating Theatre PC's running windows are not running anything important. They don't run life support systems or any of that crap so the PC's rebooting would have been a minor inconvenience, not life threatening.
Secondly, why were the PC's all left to update themselves? There is no good reason for 90% of these PCs to be on the Internet in the first place and, in any case, it's appalling bad management to let them update themselves. Updates should be being pushed out from a central location in a controlled manner and at a specified time. Even then, it can be configured so that the user is ASKED if they want to reboot now or later.
And lastly, as pointed out above, the patches were released in October but update wasn't turned off until December. So, someone, somewhere, is telling big fat lies to cover their arse..
So this is a case of management not knowing Jack Shit and making crap up to cover themselves. The Linux and Mac retards who clearly didn't bother reading the article before hitting the button they have set up to post "Ha ha, Windows failed, Linux/Mac rules" can all crawl back under their rocks now.
NHS in huge management fuck-up is hardly a news story is it?
