Windows 10: Can I re-use the key I bought on G2A after I re-install windows on the same PC?

My parents' windows are corrupted because the local technician installed a cracked version for them. Yesterday I reset the PC and changed the key to the genuine one but the windows are not working properly.- cannot download anything at all. eg., from store or Windows update- cannot repair using DSIM Thus, I decide to re-install the windows after I get the reply from this.Please Kindly advise if there are any better options.

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.
