Thank you for the post , the product keys are for 2019 version
There is Keymaker too
No, they are actually for 2020 versions. Its just typo error. You can simply use the "Find and replace" tool in Notepad and change all of them at once. But even if you leave them as they are, the Product Keys are for 2020 versions. Guys you could have looked at the 2019 versions to confirm that they are different before coming in here sounding like alarmists.
