Clean Install Windows 10 Directly without having to Upgrade First

 

Thank you, I have read the whole tutorial. Let me bring up some context. We have about 300 identical workstations running Windows 7, 8 or 8.1 in our Microsoft Active Directory Domain. License is OEM, not Volume. We keep our machines up to date with WSUS and definitions are set by GPO. Users are not able to change it. There is an authenticated proxy, integrated to AD, which let users access external world only on 80 and 443 TCP ports. The problems here are:


1) Easiest way to distribute installation. As you can imagine, we can't just let users go ahead and download Windows 10 from Microsoft, as it would put down our internet connection. So is there a simple way to provide it in our LAN? Is this already possible to make it available throught WSUS?


2) How to activate Windows 10 installation. We know that the new installation will somehow 'trust' the existing activation. Someone in this topic said how this works, but it is still cloudy for me. How can I know if the upload to Microsoft Servers was successful? How does it work in details? Is this an upload to a specific domain on a port different from 80 and 443? Is this TCP or UDP (if it is udp I won't see it using netstat)? And what happens if it fails on installation? The information is gone forever or is there a way to tell Windows to upload my machine informations again to Microsoft servers? What about using Windows 8.1 key on Windows 10. Does it really works, even with OEM installations?
