Windows 10 Pro: How to download, install and activate

Option 1: Performing a clean installation

Please proceed with this when you are currently using an older Windows version than Windows 10 or a PC without an operating system

• Installation type: Custom: Install Windows only (advanced)
• Remove all partitions and create a new one to install Windows

Option 2: Upgrading from Windows 10 Home to Pro

Please proceed with this when you are currently using Windows 10 Home and want to upgrade to Pro

1. Press the “Windows key” + “R”, type “slui.exe” and hit “Enter”

2. Enter your Windows 10 Pro product key. If it’s not accepted, apply the default product key: “VK7JG-NPHTM-C97JM-9MPGT-3V66T”

If error code “0x800f0805” appears after applying the default product key, please make sure that you have at least 20 GB of free disc space and that Windows is updated to it’s latest version. If those two points apply to you, it is obvious that some important system files are missing. In that case it is necessary to perform a clean installation (see Option 1).

3. Go to “System” – “About” and “Change product key” (Click “Yes”, if User Account Control comes up)

4. Enter your Windows 10 Pro product key and make sure all open applications are closed and your work is saved, then start the upgrade.

Wait while the upgrade process kicks off – your computer will be restarted several times throughout this process. The amount of time the upgrade takes will vary between systems. But in our experience, it only takes 5 to 10 minutes.
