Well, I'm expecting a lot from any new Windows version, not because I use it but because it could prevent people from my family to ask for help when everything got broken.
So, I have one question : does it enforce more control on installed software or is it still the jungle of spyware, adwares and viruses ?
When I saw they did a windows store, I thought that finally, I'd have a good way to tell people how to get their machine fast and virus-less : only install software from the store where software is controlled and coming from the original provider (like we do in linux : install everything from controlled repositories).
Unfortunately, the windows store is just a huge mess for metro apps, not a way to install software in a more secure way.
Windows will be a good OS the day it won't auto-destruct over time, won't require an antivirus to suck all performance out of your CPU and kill you hard drive within a month.
