Windows 10: Reset Dell XPS Laptop with Pre-Installed Windows 10 - steps?

I need to re-set my Dell XPS Laptop, which has a pre-installed Windows 10 on it I bought the laptop and the retailer put Windows 10 on it, so I don't have a Windows CD or a product key. My understanding is that with a pre-installed Windows 10 I don't need to worry about saving Windows on a USB stick to install it from after reset, and that I don't have or need to enter a product key to make Windows 10 run again after re-set.


Is that correct? I don't want to reset and then find out that I cannot use my computer due to Windows not being ready.


Once I saved all relevant files, can I simply start re-setting my laptop and the pre-installed Windows will be installed automatically?


Thanks!

You can try a manual upgraded as suggested in my previous reply using the ISO in addition to the 12 steps before upgrading.

 

Clean install of XP on Dell laptop?

My friend has an inspiron laptop from dell. He got it with Vista preinstalled on it, but wants to switch back to XP. He got an XP Pro CD, but when he inserted it, the "Install XP Now" option was greyed out. I thought it might be dell trying to make life difficult when reinstalling windows. *Confused Any advice??

If I formatted the hard drive for him, NTFS, would I be able to clean install XP or would the prob still be there?

Thanks in advance
