USB reinstall using tool

[Zalgo]

So, tomorrow im planning to try a clean reinstall of windows 10 using the official official tool using a USB. He's currently on windows 10 home 64bit.

My question is, if I do this, will I need to put in a new serial and all that? Or will it just cleanly install.

Hi,

Did your computer originally came with Windows 10? If it's a fresh install of Windows 10 in a PC that previously has a different version of Windows installed then yes you'll need to enter the product key for it.

Here's more information about Windows 10 activation.
