Question how do i upgrade to Windows 10? (read description)

[using google in BSOD]

yesterday, i bought a laptop.
and when i checked the laptop, everything seems normal like a common genuine windows 7.
i decided to upgrade it to windows 10 pro since i have the retail license key i can use for more than 1 PC. (not an installation CD/USB)
when i tried running media creation tool, it says:
"this tool can't update your windows. the language or the edition of the version of windows currently installed on your PC isn't supported by this tool"
so then i tried finding out what's wrong with this PC.
so, i typed this code in my cmd:
slmgr.vbs /xpr
from there, the notification box tell me the expiration time of my windows 7.
which means the windows 7 is activated by a kms.
i forgot to check the windows 7 license from the CMD before buying.
so the problem is:
how can i update from pirated windows 7 to windows 10 without buying more expensive stuffs in a legal way and also without any KMS?

thank you for your willing to help!

you can´t "downgrade" from enterprise to ultimate, you will need the licence key for the ultimate edition to do so. Best thing to do is buy a key for win10 (about $20) and install win10 freshly.
