If it's not worth bothering to upgrade, then why are you bothering to use it in the first place?
That question only suffers from logic and you cannot actually be that dumb.
Windows 7 does what I need. There may be some technical benefits to "upgrading" (specifically written in quotes) to Windows 10 but there also seem to be more privacy concerns and intrusions with Windows 10 and I don't need/want that. The business model MS is employing seems to be changing, like with Solitaire as a subscription service to avoid ads, and I'm not a fan.
Is MS still going to charge people for Solitaire that actually *buy* a copy of Windows 10? I imagine so and that's wrong, or at least undesirable.
This type of thing isn't unique to Windows, I object to the Unity Shopping Lens and Amazon tie-in with the latest versions of Ubuntu, but I know I can uninstall those and other things and be fairly confident that Canonical won't be tracking my every IM, email, browser visit and keystroke. Microsoft has made tracking tie-in a requirement to use just about every new feature in Windows 10 -- according to the Privacy agreement, which I just actually read. For example, Cortana doesn't require your location for everything it can do, but MS makes it so. Auto-sharing WiFi passwords is supremely stupid, especially for such dubious benefits.
The whole point of Windows 10 is to suck you into the new Windows everywhere ecosystem. You are not their customer anymore, advertisers and business partners are. You are the product.
