A really easy procedure. Download the media creation tool for Windows 10 here. That tool will create a bootable Windows 10 installation flash drive and you can clean install from the drive. And Windows 10 will auto activate since you already have an activated copy of Windows 10 on your system. In addition this YouTube video is a step by step tutorial explaining how to clean install Windows 10. EDIT: [NAME] instructions are spot on as well and more detailed. And possibly the only person that I type faster than.
Hi, I want to carry out a clean install of my XPS 8940.  I get that I can reinstall from the Dell image partition, but I'd prefer not to have the bloatware.  Thing is, I don't have a Windows 10 disk.  Is there any way I can legitimately get around this?  Maybe as I am licensed for Win10 I could download this from somewhere? Any advice appreciated - Thanks
