Sorry, my fault. It should say how much disk space not memory.
Check the setting for "Temporary Internet files".

>>Fancy meeting you here... Look on Tools|Internet Options - right there in front on the General Tab, Click the "Settings" button in the "Temporary Internet files" box in the center of the form.

>OK, yes, I saw that. I guess I'm confused. Sergey mentioned memory, and it looks like the setting for "Temporary Internet files" is for disk space?

>My original question was that disk space on drive C: (yes, where the Temporary Internet files are stored), often increases dramatically after I reboot. I can check next time to see if the amount stored in that directory changes when I reboot, but I don't see anything that implies that that space is recovered upon rebooting.
