Windows 10: Windows 10 recovery machine previously upgraded from Win10 Home to Win10Pro

I have a laptop that was upgraded from Windows 10 Home to Windows 10 Pro using the Windows upgrade process in Settings. I paid $99 for the upgrade. I got a receipt in e-mail, and I can see the purchase in my Microsoft account.


However, I cannot see what my Product Key is in my Microsoft Services and Subscriptions. If I re-install Windows 10 after a catastrophic failure, what is the Product Key I need to use to activate/legitimize Windows?

Windows 10 Club

I am building a dual boot with win10pro and win10 home. one for work and one for games.
Step by step win10 RTM got worse, no idea why. Also my X99 board was not working well, too much warm reboot locks. Updating to November upgrade was a loop-hell, just like going from 8.1 to 10, i must be damned by nighly witches.... so I decided to reinstall from scratch.
Horrors:
1. The Media Creation Tool downloaded ... W10 pre-november, so again another step needed
2. During install NO USB keyboard or mice worked, be it usb2 or 3 ports. tested with all kb's inhouse. none worked. As this never happende before I tried removing bios battery, and adding a old usb2 port... it worked! (hopefully now my OC will also be much better, lol)
3. After win8 created 2 partitions on the left: Recover and Efi, win 10 created another on the right of the system partition.
Is there a way to know if anything at all is inside these recovery partitions? Recovery never worked for me... I'd like to erase, leave only EFI...

 

Clean install of Win10Pro on machine previously running Win10Home

Vijay,

Unfortunately, that doesn't answer my question. My situation is slightly different - I had a Win10Home installation and purchased a new Win10Pro OEM key (not an upgrade). I would like to use that key to install Windows 10 Pro on the same machine by doing
a fresh install - this is NOT an upgrade, and my understanding is that the key I purchased cannot be used for upgrading. So I need to know if I wipe out my current install of Win10Home and do a new, clean install with the Win10Pro key I purchased, will it
work correctly?

Thanks!

 

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
