Window's RAM usage shows significant evidence contrary to the idea that Microsoft carries even slightly about quality. I don't understand how they can't fit the basic OS in under 1GB at the desktop. And the idle CPU usage is all over the place.
And when it comes down to it, they still haven't implemented per app sandboxing as standard or dumped old insecure APIs. Windows is a very dated OS at this point and they're not doing much to fight tech debt.
