Windows 10: How to clean re-install Windows 10 Single Language on my Lenovo Laptop

I would like to clean re-install Windows 10 Single Language on my Lenovo G50 70 20351 laptop. My laptop is having licensed copy of Windows 10 SL , upgraded from Windows 8.1. My laptop is running very slow. Hence I would like to format my C drive and clean re-install Windows 10 SL. I have with me bootable DVD/ USB (of Creators update) which were created from the Original ISO downloaded from Microsoft Website. My Windows 10 SL version is 1709- 16299.192 at present. Please advice me how to go about it, so that no Licensing issue and installation issue I face.
Thanks in advance,
aria

ACTIVATION PROBLEM WITH WINDOWS 10

I have Lenovo laptop with pre installed windows 8 single language edition, which was subsequently upgraded to 8.1. I had to re-install windows due to unstable performance. Windows 8.1 could not be refreshed as "Drive on which windows is installed is locked"
error came in. Then I downloaded the win 10 "Media creation tool" and performed clean install.

Now windows 10 is not getting registered. Please suggest what can I do. I know the win key from BIOS/UEFI but win 10 is not accepting it.

 

Windows 8.1 Core Single language to Win 10 Home different language installation

Hello,

I upgraded my Lenovo with 8.1 Core Single language /english/ to Win 10, activation was OK. After that I made a clean install of Win 10 Home /slovak language/. Now I cannot activate Windows 10 for almost 3 days. Is it due to the change of language, the fact
that slovak language is not available as "single language version" or are the servers busy? Should I reinstall an english single language version of Win 10 Home or just wait some time for the activation?
