The Microsoft deal will also allow NHS trusts to update systems with the latest Windows 10 security features.
How long will this take?
What about the x thousand of Windows XP or Vista machines that have to be upgraded and will they be able to support Windows 10?
Would it not be simpler (and cheaper) to standardise all IT equipment across all NHS trusts directly from Whitehall? Think how Maersk dealt with NotPetya, by replacing all servers and desktops/laptops.
