Windows 10: how to retrieve Win 10 product serial no. from free upgrade

Have a home HP PC that came with Windows 7 which I got free upgrade to Windows 10.


My hard disk crashed 9 months ago and tech person replaced hard disk & Win 10 charged a fee of course


PC now say my browser is "managed by your organization" and I can't find any stickers with s/n for Win7 on machine.

Can anyone help? Thanks.

Need to retrieve serial number from product key.

Hi

Purchased windows 7 some times back and later I upgraded it to Windows 10. Now some how the PC got corrupted and I want to re-install the windows.

I lost the serial number and unfortunately instead of serial number, I kept note of product ID which is not accepting as the serial number on new install.

Need some help - on whether we can retrieve serial number from product key?

Thanks

Fresh Install of Win 10 without Serial Key?

Looking to reformat a laptops HDD, and then reinstall Win 10 fresh. The problem is it came pre-installed with Win 8 and I did the free upgrade to Win 10. How exactly would I re-format the HDD, reinstall Win 10 and ensure it reactivates properly? I don't see a Win 8 serial key anywhere in the contents of the box.

 

Windows 10 serial on OEM


So I'll summarize steps made...

1. Saved serial number (taken with Belarc Advisory) from preinstalled (half chinese language) Windows 8.1 (don't know exactly the version, suspect Windows 8.1 with bing) on tablet
2. Formatted tablet
3. Tried to make a clean Windows 10 (HOME, HOME N and also PRO, everytime with the same result) install with ISO taken with MediaCreationTool, during install (and also after completing installation) it says that the saved serial is not valid
4. Tried to reinstall Windows 8.1 (ISO taken with MediaCreationTool again) HOME, it says that the serial is not valid

So i suspect that the saved serial, is from a WINDOWS 8.1 WITH BING OEM version and this kind of ISO is not accessible/downloadable anywhere (at least I can't find it, any suggestion?)

Still not tried SHOWKEY with that serial, I am in office now, and the serial is saved on a usb pen at home, will try this evening.

So I'm stucked but if everything is like I suspect, it's incredible. If I have a tablet/notebook/netbook with Windows 8 preinstalled, it seems that I can update to Windows 10 without problems, but if I want to make a clean Windows 10 install that serial is not valid...
