Slow boot time, long wat before logon screen appears

I've had my HP EliteBook for 9 days only and it's boot time is getting progressively slower!  I run Windows 7 Professional 64-bit and the notebook has an Intel i5 core 2.4Ghz CPU with 4GB RAM.  The boot portion with the Windows logo screen is fast, but getting from there to the actual logon screen takes another 300+ seconds!  I have checked the Event Viewer and no applications are noted with long start times.  I do however see a very longUserLogonWaitDuration in the details section of the Boot event.  Here is the data from the event viewer:

Session1InitDuration 1332
SessionInitOtherDuration 5127
WinLogonStartTimeMS 29982
OtherLogonInitActivityDuration 4697
UserLogonWaitDuration 1638501

The UserLogonWaitDuration took a long time!  The notebook is not configured to use a Domain Controller, hence I do not think the delay is due to the laptop trying to contact the Domain Controller.  There are also no policies applied on the notebook.  I am running McAfee Anti-Virus.

Any suggestions to troubleshoot or solve the issue will be appreciated.

    I suggest you download Process Explorer. This freeware utility performs a similar function to the Windows Task Manager but it goes much further.

    For further information about Process Explorer see here:

    http://www.microsoft.com/technet/sysinternals/SystemInformation/ProcessExplorer.mspx

    In Process Explorer please add a Column. Select View, Select, Columns, Process, Performance and check the box before Start Time. Next select "Show Processes from all Users" and click on the column header "Start Time". This will sort so that you can see start with the earliest first. You may need to click twice or three times.

    On my Windows 7 box the first item I see is smss.exe =Session Manager. You should then see a long list of items loading over a brief period of time. The boot process ceases on my computer with the loading of two AVG files (my anti-virus is AVG 2011). Before these two files is a uns.exe file which loaded this morning 2 minutes 20 seconds after smss.exe. Usn.exe is an Intel file so it may not be on your computer.

    How long does it take from smss.exe loading for the main files to load? What are the files arriving at and towards the end? How long does it take for them to appear after smss.exe?

    Hope this helps, Gerry Cornell
