There is nothing wrong with my Windows OS (7). There is no reason to upgrade... all an upgrade will do is disrupt my environment.
If I have to eventually pay for an upgrade due to end of life support, I will have saved a packet by not having my time wasted by an unnecessary upgrade now.
All it seems to be is a new DRM model, forced updates, no opt out, moving to a subscription model... it's a downgrade. Avoid it as long as you can.... don't be a sheep.
Until a DX12 only game comes out that you want to play .. then you will buggered ..
Whenever a new version of Windows appears the same thing happens .. There is always a percentage of people who say they can't see any reason to upgrade. Whilst it is right to be sceptical of any company, I don;t think there is currently enough evidence to suggest Windows is going subscription.
Even if it does, it wont be a massive amount of money, even Microsoft are not that stupid. Worst case is you might have to pay maybe £50 a year or something silly like that to keep it up to date (and thats a big maybe). Which in all honesty I would be perfectly fine with myself.
Whilst Windows 7 / 8 are fine OS's at some point you will have to upgrade ... its unavoidable
