To be sure that is the situation here. Where is breaks down is when the machines need different drivers for best operation.

Then there is the new security policy/software update of the day, which is always pushed out in mass, without notice. It's supposed to only happen on Thursday. But there always seems to be some threat so despicable that it must be patched now.

The week after patch Tues. is alway hell. A system that had been running smoothly will just get squirrelly. It usually takes 2-3 restarts to get sorted.

Mind you, I'm all in favor of AV software as a necessary evil. But it's kind of hard to swallow the hit when I routinely open 2000+ files during a day. (Cad software does that these days)
