Sorry I support this 110%
Because it cuts down on the stupid people installing bugs which is better for all of us. If you want an example the only time I have ever had to throw someone out my PC shop was during the Win 7 days, he bought a new PC and wanted me to install Limewire on it. I told him "The FBI shut down Limewire years ago, I will be happy to show you how bittorrent works but Limewire is long dead" so what did he do?
You guessed it, promptly went home, installed a malware program someone had stuck the Limewire icon on, when the AV told him plainly it was a virus he UNINSTALLED THE AV and then when he had his PC completely pwned and was so infested it couldn't even load a webpage he tried bringing it back and demanding I fix it for free. When I threw him out the shop he was screaming "It says right there that it is Limewire YOU MAKE IT WORK!" like a fucking baboon.
So yes people with a BRAIN can get around this, those like Limewire boy? Cannot which is the entire point! Microsoft has realized that there ware waaaay too many computer users that are "sniff your own farts" level of dumb and there is nothing they can do to raise their IQ so making a bar that the truly moronic cannot overcome? I support 110% if for no other reason so we don't get millions of PCs in botnets thanks to these geniuses.
