Hello Andre, Thanks for sharing this helpful guide and for you work! This method reduced of about 30 seconds my boot time, but it's still a bit high (more or less 2.30 minutes). I've completed a boot trace and I would be very grateful if you could have a look at it. http://www.mediafire.com/?sgt4pxuqce971gx (I run it twice, the first time with drivers and I get the bugcheck, the second time without drivers). Note: 1) I had to enable the auto logon creating the registry string, but even before it was pretty slow. 2) the entire HD is protected by TrueCrypt
