Welcome screen hanging and bootvis

Hi, I'm trying to speed up my startup a little, and need some help understanding what bootvis is telling me.

My computer loads quickly once it gets to the wallpaper. It takes about a minute on the loading screen and welcome screen, though. Since it was at those that it hung and not the loading of programs at the taskbar, I decided to try using bootvis to see what was causing the hangup. Now, though, I'm not making much sense of what it tells me.

I ran bootvis, then told it to optimize startup. The odd part is, before optimizing, it booted in 60.83 seconds according to bootvis. The second trace scan, after optimizing, said it boots in 66.33. The main culprit is the 'shell' bar in the boot graph, which means nothing to me and I cannot seem to get bootvis to elaborate.

Before optimizing, driver and prefetch took about 25 seconds each (overlapping), and the shell took about 23. After optimizing, driver and prefetch each took about 17, but 'shell' took 38.10.

I tried to search the drivers to see if it was one of them causing the slow boot at the welcome screen. One, shockprf.sys, took longer before optimization, but took much less at the second boot. The InCDfs.SYS driver has constant 2.0 increments along the startup, both boot times. Would that mean it could be having problems and slowing the boot time?

Can anyone tell me what is loading during the 'shell' loading time, how I could possibly make it faster, or how to understand what bootvis is telling me, so that I can improve boot time?

The computer is running Windows XP Pro SP 3, and I swear I know more about running it than I seem to with this question. If I have been unclear or left anything out please let me know.

PS: This is not a new thing, so it's not virus or spyware - I just haven't had time until now to try and speed up the boot.

About Bootvis.exe
Bootvis.exe is a performance tracing and visualization tool that Microsoft designed to help PC system designers and software developers identify performance issues for boot/resume timing while developing new PC products or supporting software.

Contrary to some published reports, Bootvis.exe cannot reduce or alter a system's boot or resume performance. The boot optimization routines invoked by Bootvis.exe are built into Windows XP. These routines run automatically at pre-determined times as part of the normal operation of the operating system.
If you are an end-user seeking to resolve issues for boot/resume performance on your PC, we recommend that you contact the vendor from whom you purchased the PC. For information from Microsoft on specific issues, you can search Knowledge Base for Windows XP product issues related to "resume time."
