Windows 10: Why do Windows 10 clean install starts from 30%, instead of 0%?

When i try to make a clean install of my Windows 10 Pro, the clean install starts with 30% already achieved. Why is this happening? Why is the Cloud download starting from 30%, instead of 0%? Is it because the clean install option downloads 70% of files from Microsoft's server, while the rest 30% of the files are used from the already installed Windows 10 on my computer? When i start clean install and click on Cloud download, this is how it starts:Instead of starting from 0%, it directly starts from 30%, as if 30% of the files are already downloaded. I think that clean install downloads 70% of

Clean Install Workaround for Vista

You may remember this news story on techPowerUp! a couple of days ago relating to the lack of clean installs when using the Upgrade Editions of Vista, which required an old OS to be installed. However, Paul Thurrott has managed to find a workaround for this issue, which ironically lets users do a clean install Vista without any previous version of Windows, albeit a little tedious. Here are the steps:

• Boot from the Windows Vista Upgrade DVD as normal
• When prompted for a product code, leave this blank
• Select the version of Vista you have purchased and let Vista install
• When you boot to your desktop for the first time, run the Vista setup from Windows
• This time enter your product key
• When asked whether you want to do an Upgrade of Custom install, select custom and choose a clean install
• Windows will now install for a second time and you should be able to activate it

Remember, these steps are only advised for use in order to achieve a clean install of Vista, it is only legal to use the upgrade editions if you have previously purchased the appropriate version of Windows.

Clean Windows 10 (?PRO?) install

I have bought a legit "Windows 10 Pro" key of a key website. It is legit since i'm currently using it for over a year now. I currently have Windows 10 Pro installed on my PC and I want to do a clean install. I just can't find the windows 10 Pro download in the tool. But if i could use a windows 10 pro key with a normal windows 10 install, I'll be good to go.
