Please correct the below text:
I have installed a pirated copy of Windows on my computer. Now I'm continuously getting that message which says something like you don't have original copy of Windows so cannot get some of the important updates. I have a original key for Windows. Therefore, is there any way that I can use this new original key to validate my copy of Windows without reinstalling the Windows? Do you know of any forum where I can post this query? Thank you for the help in advance.
