Windows 7 to windows 10 upgrade query

Click "I don't have a key" and continue on. It should activate with a digital license key after upgrade and going online.

"windows 7 pre media" no such version.

windows 7 home premium can only upgrade to 10 if you have WINDOWS 7 home premium COA sticker. 

If you had RETAIL windows 7 there is no upgrade.

You can use OEM DVD to install with the I do not have a key option and choose HOME or PRO depending on the COA key.

If this system has XP or VISTA COA you MUST BUY A NEW COPY of windows.

there is tool to run to scan BIOS for COA'

sure is.

saves lots of time wondering (for  sure failed)

here is that great tool and I have tested it .

IF YOU SEE MSDM there, bingo COA, there. all in 15 seconds work.

LINK TO TOOL (nirSoft is great maker used by me for years, all their tools)

no PC stated at all (it has number) and has MT ,DT ,SF,F  USFF, Micro or AIO case CLASS TOO.

therefore the  class of BIOS iis unknown.

if PC is w8 era it has a license now stored in BIOS, (UEFI same) w8 most times upgrades for free.

home to home , pro to pro, etc.

so if you click activate it works,  if not you buy a w10 COA key , MS (not dell) real OEM keys are very cheap. $5.

but have zero MS support, they are builders keys.

that is all the hints  .

Next time please tell what PC you have,  here is the huge  list. back to 2003

no way can anyone guess, or answers 10 ways from Sunday. even wrong. (anyone)

"buy a w10 COA key , MS (not dell) real OEM keys are very cheap. $5."

Where do you buy these licence keys for $5 ??

On every system I own that was running Windows 7 or 8 I've simply created an install USB stick by going to the Microsoft Create Windows 10 installation media website and then installed it to a blank hard disk or SSD.

When asked for a serial number I simply choose 'skip' and it's always activated without an issue. It's sort of an unofficial "free upgrade to Windows 10" that still works.

You will obviously have to back up all your files and be prepared to reinstall all your apps. Windows 10 is pretty good at installing all the right device drivers There might be easier ways to transfer files and settings, etc.. but I just start from scratch and it makes for a very clean install without any old stuff that might get in the way of things working properly.

If you first back up your whole system with something like Paragon's free backup utility you can always restore your old system:

Easier still is buy a new hard disk or SSD to install it on so you can just pop in the old drive if things don't work out.

Probably eBay.

Cool. Wonder if they are genuine, and why so cheap? I thought windows costs well over $100.

I bought a Win10 DVD off of eBay for $20.  I used it for a clean install on an SSD.  It worked perfect.  It's not a copy somebody made.  I thought that was a good deal, but lately speedstep has been linking $9.99 DVD's.
