Windows 7 logs you into a temporary profile

I believe lots of people who use Windows 7 have seen the following message:

"You have been logged on with a temporary profile. You cannot access your files and files created in this profile will be deleted when you log off. To fix this, try logging off and logging on later. Please see the event log for details or contact your system administrator."

This happens when your profile is being operated by a process, and you log in using the profile.

To solve this issue, it is very simple, being patient, give the computer several seconds to run the starting up processes. For example, if you just log off the computer, wait for 10-20 seconds then log in, it should help you avoid the message mentioned above.
