I have survived the Windows 8.1 installation/upgrade/service pack one, even the gaudy bit at the end where the screen goes from green to purple to Schiaparelli pink to orange to red and lands on the dreaded purple start up screen. It took two hours from start to finish but I could work on my desktop computer as it downloaded files so it was really only the last half hour where it reboots and reboots and sets things up that I had to wait and watch. It is actually a very straight forward and self sufficient installation and did, in the end, restore all my settings. It changed the start screen from purple back to the green I had chosen. There does not seem to be a lot of difference at the moment but what were they thinking with those ginormous orange arrows that pop up in big black squares to tell you how to use charms and toggle between start and desktop? Surely , if you are installing 8.1 , you have already installed Windows 8 and know how to navigate it? Maybe not. Microsoft is either being over obviously helpful or does not suffer fools gladly. Using the corners of the screen is important on Windows 8. They have changed bottom right to a Windows logo so you quickly navigate between screen and desktop. There is no start menu because this is Windows 8 and the layout has changed. To get to Run you use Windows key R. To search it is Windows key S or use the top left had corner and do it from Charms. To find a file you can click on the down arrow on the start menu bottom right or you can type Windows key F or use the Charms bar. I am desperately hoping I can get rid of those massive orange arrows. It has added Food and Drink, Health and Fitness , Help Tips and Reading List tiles to my start screen. Must have thought I am somehow inadequate but I’ll investigate them. The food and health ones scroll pictures so they add to the visual appeal of the Metro start screen which I really do appreciate. So, at this stage , it has all been easy and my only need is to make those arrows vanish. I have not had to change , alter or manage a thing. The installation took care of everything.
