I don't think it's a bad thing. MS is being forced to support a bunch of old OS's. W7 ended mainstream support in January 13, 2015. W8 will end in January 9, 2018. Yes they have extended support until early 2020, but it costs a ridiculous amount, and for what reason? Because people only have 3gb of space on their computer? I mean really...
My advice is to go to an electronic shop, buy a cheap flash drive ($5 for a 64gb, I think you can afford it), dump as much of your files onto it as you can to free up space, then run the update.
You maybe should see a doctor if you think that whoever came up with the idea of updates needs to kill themselves. Practically every modern piece of software has forced updates. Welcome to the 21st century.
