Before the most recent MS security updates my Windows 7 seemed ok.
After the security updates the image previewer freezes a lot when I'm clicking the arrows to go between images. It'll work fine for a few images and then freeze. Sometimes it'll recover and work after a few moments and other times it says "Loading" forever.
Studying this problem more I see that Windows is creating 50MB temp files on the hard disk when I preview images even when the images that I'm previewing are less than 1MB. Why is Windows hogging the hard disk bandwidth like this and how can I make it stop?
