My computer wasn't having it yesterday morning, had been asking me to "update" to which I picked everything except update now for a couple of days. Then it decided to start me off with a black screen, wouldn't bring up desktop, so I had to. Not sure where all my information goes on those things but I'm sure the update wasn't totally necessary
As annoying as it may seem... most of those updates are fixes to not just the performance but identified security issues that hackers figure out. Good to keep your laptop up to date... phones as well.
Flip side is that as the OS and Apps advance, your old phone or computer will be made obsolete as they build toward the newer machines on the market. That's why I have stayed with factory refurbished. Save a few bucks and I know a technician has been through it.
