>Consider why we care about security in the first place: >- We don't want our private data stolen >- We don't want a malicious program stealing our electricity and computing resources >- We don't want adware injecting advertising into our browser toolbar, homepage, email client, etc >- We want our family to be able to safely use our computers without having to worry about them falling for scams >- We want peace of mind Almost all those points are basically the same thing repeated differently: We don't want somebody else mess with our computer, but that "somebody else" almost always is 3rd party - so not you (user) and not Microsoft (vendor). Ads from vendor aren't considered as a security issue (unless very edge cases). They are annoying, but in the principle they aren't security defect (unless badly implemented)
