One of the things I love to criticize MS for is their "user account control" : gee, looks like you're actually trying to....USE.... your computer for something.

One of the things I love to criticize MS for is their "user account control" : gee, looks like you're actually trying to....USE.... your computer for something. You know, actually ...USING...your computer might damage it. Since making a secure platform isn't profitable, we'll just make the screen darker, cause you know, darkness kills the spyware. See, the signing system doesn't have to be mandated. It could pop up a UAC-like screen but with an actually useful message: this code is known to have malware, we recommend you dont run it. If you absolutely want to, press OK at your own risk. Another message could say it's completely unsigned, so devs could still write and distribute their own code. But make it free to submit to the "app store" and get reviewed by MS. That would work wonders to improve security across their whole ecosystem, and not force anything down the users' throats.
