Every time I use Microsoft Windows, I manage to find another way it simply doesn't make sense to me.
In this example, I have instructed Microsoft Outlook to “Save All Attachments” from a particular e-mail message. Instead of saving all of the attachments, it pops up a modal window asking which attachments Iʼd like to save. Well, Iʼd like to save them all. Which is why I clicked on “Save All Attachments” and not “Save some, but I'm not sure which ones I might want, so why don't you stop me in the middle of my work instead of doing what I've instructed you to do.”
There would be no shame in Microsoft adding a “Save Some Attachments…” item to its already ample menu structure.
