It's clear to me that many don't understand the real situation by just assuming that it can be forced by MS (they will NEVER do this to millions of big company customers, it is shooting your own foot) or that you can just update or throw away apps. It's not apps really. It is platforms. SharePoint and others. You can't simply replace a platform if all of your apps or business critical apps rely on it. It is not a case of getting rid of Flash player. Apples and oranges. Replacing such platform requires not just investment, it will break business operation, require new expertize and service providers. There are also platforms managed by governments. I know at least one which is made with EU funds to manage EU funds and it only works correctly with IE (it is actually made with Java on Tomcat, so not some legacy platform here) and nobody is going to change that. You can't say to them that you want to use Chrome and throw away IE.
