Yes, well in Linux, if you screw up you're covered by your EULA's. People just don't download your distro until you fix it.
Microsoft is a multinational corporation with their OS installed on billions of machines around the world. If they screw up one of their 'distros', then it can cost them tens of millions of US Dollars. DAILY. Until they fix it. Granted, this is mostly on the stock market, but even so. They have pretty good motivation to not screw up like this.
Not to mention that someone could very likely sue Microsoft for losses caused by the OS arbitrarily deleting sensitive data.
