I run in full screen, but also I have windowed mode setup to be nearly full screen. I usually switch to windowed mode - using the normal Windows type buttons in the upper right of the screen - to use the browser, etc., and then switch back to full screen (again using the buttons).
But, in any case, whether doing it that way, or using alt-tab, it doesn't take any significant time to switch between modes. There must be some other reason for it to take you 30 seconds to go back to full screen - driver issues, low RAM, etc. Make sure Windows and all your drivers are up to date.
What graphics do you have? What version of Windows? How much RAM? How much empty hard drive space?
