I have been manually dowloading updates since the incident of the bad updates some months ago. As a general rule, I download the important and skip the optional. But what am I to make of "Microsoft .NET Framework 4.5.2 for Windows 7 x64-based Systems (KB2901983)" I have tried to read the supplementary material but can't see why I need this. Is everyone getting it? Is it necessary for ordinary users who don't need languages other than English? TIA.
