Windows *IS* and infestation.

It would reduce security?
I just placed a one dollar bill on my desk, and next to it I placed a
hundred dollar bill. What’s the difference between the two bills? Both
bills are composed of the same thing – linen and cotton. So what’s the
difference. The difference is the writing on the two bills. Both say
they are legal tender ‘ for the payment of all debt, public and
private.’ The only real difference between the two items is that the
Treasury states that one will pay off a dollar of debt while the other
will pay off a hundred dollars of debt. Thus, this nation’s money has
been degraded to the point where the writing on a piece of paper tells
you what the thing is worth. This is money by government edict or by
fiat. Intrinsically, neither bill is worth a damn thing. And ultimately,
they’ll both end up as bookmarks or museum pieces.
