Upgrading to a newer windows version can sometimes be a big challenge. Especially when more people are involved, like in a company.
You want everybody to feel comfortable in your way of deploying, but also in the way the users will use their new windows version every day.
I thought it can come handy to deliver a brochure / how to for your users. I feel that lot of people are scared of the windows 8 version. And the lack of the start button is not gonna arrange that.
So, to make your users feel a bit more comfy, you are looking for a clean example of what is new and what people would like to learn.
After looking a couple of times over the internet, I have found this nice brochure of Microsoft which you can download freely.
This can be a good base for your own how-to manual, that you can customize for your own company ofcourse.
