content: 85% of desktops and laptops are Microsoft and a good percentage of those are using out of date and unsupported versions. Not to mention half of the retards I know who consider themselves system builders use sketchy pirated versions of windows from sketchy torrent sites with 0 updates.  My company for example runs XP on all it's desktops and windows 8(not 8.1 with the service packs) on citrix clients. Seriously I got a brand new 6 core xeon and they wiped windows 8 to install XP and rebated the fucking os, I'm not shitting you. And no one's allowed to use anything other than internet explorer, so even connecting to our own companies website causes it to hang up. And I got written up for running a laptop with Slackware on it to use an SAP client that wasn't compatible with windows IE. So it's no wonder Microsoft would have the most vulnerabilities no one bothers updating it to begin with. Even it's corporate customers are complete fucking retards.
