Windows 10: Do I need to buy another Windows 10 usb drive if I forgot original key?

About a year ago I needed to make a fresh install of windows.

So i purchased a Windows 10 USB stick and everything worked. No problems at all.

However while I still have the USB stick, I have lost the product key I used to activate it.

If this current hard drive someday fails, will I have to purchase another Windows 10 USB?



Thank you all in advance.

windows 10 key

Google and download the "Windows 10 media creation tool"

Create a USB flash drive ISO and that's all you need...it will work without needing a key..
Just skip past entering a key during full install and delete all partitions, format, create new drive and install...

As long as you have upgraded from Windows 8 first...you need to do that prior to using your Windows 8 key for 10.

 

Is it time for Windows 10 already?

Here's a good step by step guide on doing a fresh install.

Windows 10 USB boot

Hi there, am not a windows 10 expert. I have a pc in the bedroom on windows 10, I messed up the bootloader trying to fix the xp on that system.

System wont boot, trying to repair via win 10 usb installer.

Downloaded the media creation tool to install windows 10 installer on usb stick. Not compatible with a host of usb sticks I have. Tried the usb sticks that others use, but I think they use rufus; as the media creation tool by win 10 does not detect the usb stick.

So quick question, the win10 machine i am trying to repair the bootloader is a win7 upgraded to win10.
If i were to use the usb win10 installer to "repair installation" does the version of the iso downloaded via the media creation tool matter?

There is three options:
Windows 10
Windows 10 Home
Windows 10 N

Also is there a step by step instead of using rufus as I want to try an alternative method of creating a usb win 10 installer. Preferably with more compatibility.

System is a asus sabertooth 990 (r2?) with AMD phenom X 6.

Also is there any other software I can load onto the usb that can repair the bootloader easily?
That would be the ideal alternative. Thanks
