windows update is a well known malware vector, how does this warrant any news? if you absolutely have to use windows, you either go through the effort of stripping the particular version you chose from all the spyware and malware it comes packaged with and gut the malware loader paths out of it, or you accept that you're running a botnet node you have little to no control over.

this is the only valid, reasonably sound and grounded comment in this entire discussion, bravo.

p.s. not being sarcastic
