I even got a MS UPDATE on my older XP-PRO computer not too long ago. Don't know where that came from... Also don't know if that was a SYSTEM update or maybe one of the MS Programs I have on that machine - MS OFFICE 2007 maybe...
They keep coming on my WIN 7 setup... I have auto updates set with it...
I am running FIREFOX here with three or so "FREE" anti-virus and anti-malware programs I usually run about every two-three days... WIN 7 runs fast all the time doing this... Even my older M90 XP-PRO purks right along on my COMMs HAM/EMERGENCY RADIO setups.
