Microsoft simply doesn't have luck with user interfaces in the last years. They tried with big change in Windows 8 and users reject it. Then they take a step back and prepare Windows 8.1 with some important changes, but the majority of users are still against them.
We expect Windows 10 to launch in late 2015.
Windows 10 will be a free upgrade for Windows 7 and Windows 8/8.1 users during the first year. If you do not upgrade in the first year, you will be charged. All details are still unknown.
I tried Windows 10 (preview) now and it looks encouraging. But everything isn't just gold. For example - during the Windows 10 installation, you will be asked to sign in to your Microsoft account. What if you don't have one? What if you don't want to use it? What if you are just installing system for someone else? You have to know, that many things are connected to Microsoft account. A downside is that, whenever you log on to
your Windows computer, you sign in to Microsoft’s cloud. Many things are synchronized from there - in my case, I installed a Windows 10 preview for my colleague and when I use my Microsoft account, Windows starts to synchronize my OneDrive files with a new Windows installation.
In a corporate environment, it is recommended to use local account and corporate domain, not Microsoft's cloud. If you use local accounts, you can create user accounts in Local Users and Groups.
So, let' look how to skip this annoying signing. I formatted the disk and tried again with bellow described steps to skip using Microsoft account in installation.
Here is simple advice how to install Windows 10 without Microsoft account.
Start installation, follow first steps and stop when setup asks you for your Microsoft account username and password.
You need to click Create a new account.
On the next page, you will find the option to sign in using a local account at the bottom of the page. Click Sign in without a Microsoft account.
You will be able to create a classic Windows local user accounts WITHOUT Microsoft account.
Later I heard that installation without a Microsoft account is also possible if you aren't connected to the internet between setup.
