Yes, it does work. Just last year my shutdown took a crazy 3 mins to complete. Searched for a soultion on MSKB and it led me to this programme. I installed it and used it to create system log files that show which are the programmes that cause this shutdown problem rather than get it to shutdown the programme itself. Shutdown the computer with one more 3 min shutdown, restarted, looked at the event log files and found it was Creative Control Panel! Then I used MSConfig to shutdown this programme, and problem solved and uninstalled UPHC as it had warned it might cause confilct.

I recommend using it to pinpoint the programmes that cause trouble then take steps to remedy it yourself. It requires full admininstrator power to install so unless you have such power over your office computer then you'll have to talk to the IT admin.
