Windows 10: How to remove windows 10 Product key without losing data?

I didn't know where else to ask this but here,so basically i brought a windows 10 key from kinguin(a key selling website)and i realize now it is no longer legit despite it working many years as i went to connect my pc with my phone it then asked me to sign into my windows account,which was not mine and just a outlook email with a bunch on random numbers and letters.I didn't realize this was not legit until now so i would like to buy a legit version of windows 10 with my actual microsoft account(which works fine on the windows store) so i can access admin settings.Can i do this by removing the product key then buying a new windows? will it let me log into my actual account with the new version on automatically log into the current account(which i have no idea what the password to is or whose account it is im guessing its a cracked one.)

Can someone PLEASE help me with this,Thanks.

windows 10 key

Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?

 

Removing windows without losing my WIN key

I guess i wrote it wrong... i have the key but i wanna know even if its removed from the computer, will it be deactivated from MS data base so it can be activated again *Big Grin

 

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.
