I have installed the new version of Windows 8.1. The upgrade process was smooth and easy. I have an enterprise edition and updated from an ISO file. The ISO loaded from an internal hard drive so no optical drive involved. I preserved all my settings and apps; so far so good.
I did have an issue with one piece of software Pinnacle Studio 16. Being a long time user I have had previous disappointments with OS updates. However much to my delight the Pinnacle forums had a link to a solution provided by Corel the new owners of the product. That’s the only hiccup so far.
The start menu update is welcome, clearly a response to user feedback. I do like the new arrangement whereby you have to put things on the start menu rather than everything cluttering it up.. However I still use the task bar for frequently used applications. Then there is the return or the start menu. It is underwhelming reminding me of redundant air scoops on faux sports car. It is really not necessary.
Overall it is a good and welcome update. Windows 8 was OK not quite another Vista moment. I suppose the interwebs are already abuzz with Win 8.2 rumours.
