Shut the PC down last night, 2 small windows updates were installed.
Today I boot my PC to the following messgae.
An important choice to make: your browser--------------------------------------------------------------------------------
Your browser is an important piece of software on your computer. It is what you use to surf the internet: it’s the window around the web sites you visit.
There are many browsers available, each with a variety of features. On the next screen, you can select and install any additional browser(s) you want.? and MS.
So it's now obvious it's not an MS thing as they would be 1st inline.
Why are they allowed to do these things to our PC's, Yes I know I could have cancelled it, but it shouldny have been there at boot up in the 1st place.

Please Note: The Browser Choice update unpinned your browser, Microsoft Windows Internet Explorer, from your taskbar, but you can pin it back if you want. Click here to learn more.
Internet Explorer is still available from the Start/All Programs menu.
Before proceeding, please confirm that you are connected to the internet.Just for the hell of itI clicked ok and now have a new icon on the desktop.
5 browsers to choose from, Safari, Firefox, Opera,
