Couldn't wait any longer for the upgrade to begin so I used Microsofts own tool that worked flawless:
http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install
I only had to uninstall one software before it started. The first thing I noted was that Edge couldn't always play flash videos but it still worked perfect in the latest versions of Firefox, Opera and IE. After a little search I was able to fix the issue by simply enable software rendering but I still miss all the nice addons like ad-blocker, Ghostery etc that makes the strolling on the net smoother. If I understood it correct addons option in Edge will be added later so until then I will be using other browsers.
The second thing was non 100% working codecs. My previous version Windows 7 Pro didn't have those kind of issues but I do remember it was very similar when Vista came out. After tested all versions of K-Lite and even Shark007 back and forward as sometimes it played my videos and sometimes not and never .mts I started to think I might had to revert the upgrade but after another search I found codecs called " Media Player Codec Pack v4.3.8 " that finaly worked on every single video file but only with the MPC-HC ( Media Player Classic Home Cinema ). Why that's the case I have no clue but I don't care as long atleast one media player works but...I wasen't to happy to find out that this codec suite is infested with PUP and adwares. For some unknown reson the codec pack thought it installed itself on Windows 8 and I was able to decline the extra included crapware so I guess that saved me from anything unwanted as after alot of scanning in safemode ( McAfee, Sophos, Msert and Emsisoft ) I couldn't find anything malicious but it's still a risk so either I keep it or use a system recovery point or reinstall the whole enchilada.
Access safemode wasen't just as in the good old day simply press F8 after BIOS start. Was forced to use a much more complicated path that involved holding down the shift key and at the same time do a restart etc.
I'm not the greatest fan of the extrem integration of my live or hotmail account as I see it as a direct automatic higher security risk if someone is able to access my pc and especially if I connect my creditcards. It's ofcourse possible to disable the mail option and just use local accounts instead and it wasen't atleast for me set as on by default and that's good. A small recommendation would be when installing apps to only use the mail access for the specific wanted app.
Nevertheless for now I will stick with Windows 10 and keep learning...
