Bought an pre-built but want to have a fresh copy of windows without all the bloatware.

I can use the windows key of the pre-built right? How do I find that?

The easiest thing to do is a system reset. Type "reset this pc" in the search box and follow the prompts. Your system will restart and install a clean, Microsoft only, bloat free version of Windows 10 with the license intact.

Thinking about doing this when my new Dell arrives in a couple of days.

I'm sure you can just download the windows 10 media creation tool and either burn an iso or create a bootable usb drive. When it asks for a key you just skip it since the key is embedded in the bios (or something like that). So when it's all installed and up and running, windows should activate automatically.

That is what i did when i updated my other computer from windows 7 to 10. All i had to do there was upgrade to 10 and make sure that windows 10 was activated. Once i verified that i just did a clean install of windows 10 with the method above. Worked perfect! I did that so I could dual boot my original windows 7 with windows 10 (i have windows 7 cloned on another drive so I just cloned 7 back to another partition and both windows 10 and windows 7 are activated and dual boot).

If win10 is already installed on the machine, all you should need to do is get clean install media (MS offers a downloadable USB option which works well) then boot from it just like you were installing it fresh. for shits and giggles when the installer boots, I'd delete any existing partitions and create new one(s). The install and activation should go smoothly, as the win10key is embedded.

I recently bought a Dell with a Win8 key and had to first upgrade to win10, then do the fresh install method I mentioned. MS has now eliminated the need for the upgrade step, thankfully.

Prebuilt from an OEM or prebuilt from custom parts are two different things. Who is the manufacturer of the PC?

Good to know because that's what I had to do as well. Upgrade first then clean install.

A bit off topic, but if you upgrade from 7 or 8 to 10 and try to go back to your previous version from 10 it will not let you if you have run the media creation tool. It replaces a folder that is needed to do so. Good thing I have my windows 7 cloned to another drive so I was able to clone it back to another partition and have both dual boot and activated.

You might void your warranty of your machine (if you still have) . So, Think before removing your OEM software.

What basis do you have for this? Can't say I have ever heard of this at all.

I just got done doing a clean install of windows 10 on the Dell i3847-10000bk that I bought for my daughter from staples. Using the media creation tool to create installation from usb went perfectly! It didn't even ask me to enter a key!

I'll be doing the same when mine arrives tomorrow.
