Now you might be thinking, “I have to grant every program full access to my computer for it to update itself? That seems silly”. And you’d be right. There’s no reason that every random program should be given full access to your machine. That would be like a bank giving keys to the vault to every customer that walked in.

If Microsoft ran a bank, the vault would be empty. Read more…
