I'm kinda understanding better now - but still not convinced that the Registry hack of which you mention doesn't also perhaps come with some disadvantages, security-wise. Still, I've no special interest in it because I've long since switched to the Apple platform instead. The only reason that I still keep my WinXP machine alive at all is to be able to still run an expensive photoeditor on it (without photoeditor updates) that happens to be a Windows-version only.
I was aware that many commercial organisations, both big and small around the world, who were still using Windows XP in the first part of this decade complained en mass when Microsoft first announced that it was going to terminate support for XP in 2013. As I recall, that then caused a rethink by Microsoft, and they extended support for about a further year. Thereafter, I vaguely recollect getting little or no response from the Windows Update website. From that point on I lost all interest in XP and Windows machines and decided to switch to Apple instead.
Are you sure this 'permanent' extension has perhaps applied only to the Professional version of XP? That's the version, I'd imagine, that most commercial organisations would have been using. Also, with generally use of working memory increasing these days beyond the 4GB limitation of 32-bit Microsoft machines, it possibly wouldn't have been worthwhile for some organisations with 32-bit-only machines to struggle on with XP, and my guess therefore is that a good many will have bought new hardware and upgraded to Windows 7, 8 and beyond.
