Hi, 
  
We're trying to install IE9 as part of our OSD. This is software deployment step within the OSD TS as the original Windows 7 capture has IE8. 
When deploying a customised MSI (using the IEAK9) the installation completes fine however when the first user for the new machine comes to try logging on the following error is displayed: 
  
The User Profile Service service failed to start. 
  
The error is due to the following file located within the default user profile either being unreadable not accessable - 
  
C:\Users\Default\AppData\Local\Microsoft\Windows\Temporary Internet Files\SQM\iesqmdata_setup0.aqm  
  
Deleting the above file resolves the problem, similary changing the permissions the file also fixes the problem. 
  
Can anyone explain why this is happening and what resolution i can try? (I want to try to resolve the issue rather than adding a step to delete the file) This occurs on both x32 and x64 environments. I've also experienced the issue when deploying the same package to an existing Windows 7 machine that's already in use by a user. After the installation and reboot, the existing user can log on however no new users would be able to. 
  
Deploying an uncustomised IE does not cause this problem. 
  
Thanks, 
Doug
