Microsoft has actually had a pretty good security record for the past decade now... Most of the truly stupid decisions regarding security were prior to Windows XP.  Since Melissa&#x2F;ILoveYou and several other worms that wreaked havoc on data centers i the late 90&#x27;s and early 00&#x27;s there was a massive shift in terms of security conscience at MS.<p>There have been attack vectors since, but that is true of every platform, and since Windows 7 in particular, most of them have been from third party software.
