Vista hangs while switching to/from Secure Desktop after Windows Update installed a new sound driver. Please help me fix it.

HP Pavillion dv6449 laptop with pre-installed Vista Home Premium.
Recent Windows Update attempted to update Conexant sound driver. Install failed. Upon reboot, no sound. Went into device manager, removed driver, Window reloaded it, sound fixed.
Ever since then, the PC hangs 5-20 seconds coming back from secure desktop. I've disabled UAC eliminate some of the lags. I have the system configured to require a password on wake-up from standby. Laptop wakes up instantly, login screen appears instantly. Type in password, screen goes blank, hear the "da-dink" sound effect, then screen stays blank for 20 seconds or more before desktop appears.
Actions that would invoke the secure desktop (UAC, ctrl-alt-del) act the same way, but delay is only 5 to 10 seconds of blank screen.
This definitely did not do this before the borked driver update. Secure Desktop activations/UAC prompts flickered and appeared instantly. Now these delays are driving my nuts. I hope the pending release of SP1 on Windows Update might fix this, but if there's anything I can do in the meantime to troubleshoot and fix this please let me know.
I'm quite technically experienced on older versions of Windows, but my technical knowledge and troubleshooting skills are limited on Vista.
