Why not switch to Linux if updating Windows is such a pain in the ass? The reality is that these updates are there for your own benefit.
When you look at the Desktop/Laptop Operating system market share, MS Windows has close to a 90% market share. So if a vulnerability becomes available on say Windows 7 (which no longer receives updates) you're almost guaranteed that 4/10 machines in the wild will be vulnerable to attack. Now say you're running Windows 10 (25% of all PCs based on some reports run Windows 10) and a vulnerability is discovered, but it's patched within 2 weeks. We can assume that 75+ % of machines will automatically download, install and reboot to apply said update. This still leaves a significant chunk, hint : it's more that all Apple Mac OS machines, of potentially vulnerable systems.
If having your PC reboot is more annoying than ransomware or becoming a puppet in a botnet your priorities are a bit skewed. I can agree that updates to Windows have not always gone down as smoothly as we would have liked. But based on some of the stats I have updates to Windows 10 are less likely to break or affect you negatively than Windows 7.
With Windows 7 the likelihood of an update causing some disruption (e.g BSOD, driver or application failure) was around 1:40; Currently Windows 10 is in the 1:150 range. Microsoft has been getting better at this, keep your systems up to date.
