Windows 10 free upgrade is still available using Windows 7 and 8 product keys | ZDNet

Since the above link shows that people are still able to get free upgrades, it would be good to give time for Microsoft updates to clear everything out for sure.

I suspect there's a difference between someone actively seeking an upgrade to Win10 as mentioned in your link, and someone trying to prevent an unwanted upgrade. From an article in PCWorld, I understood Win10 will not self install after 7/29 and the nag screen will disappear. But I agree there is certainly no harm in keeping that program active for a while just to make sure.
