User issue-- "itunes has stopped working"

Question

This week I have been unable to access iTunes, instead receiving the following error message: "iTunes has stopped working."
I have reviewed earlier discussions, especially this recent one:
http://discussions.apple.com/thread.jspa?threadID=1464059&tstart=15
I have tried most of the suggestions, but I have run into a few roadblocks that I wanted to see if I could get some help with. But before all of that, I wanted to note that I created a new user account and was able to access iTunes that way. Unfortunately, however, this is not a good long term solution. I would like to try to resolve whatever issue exists with my user account.
With respect to the potential solutions identified in the earlier post:
*“Completely Remove iTunes and Quicktime”*
#17—no such files existed in my windows\\system32 folder.
*“Empty your Temp directory and restart”*
I got the following error message :The action cannot be completed because the folder is open in another program. Close the folder and try again. I thought that I had closed all of the applications.
*“Clean Up iTunes installer files on the computer”*
When you click on the link under this suggestion, you get a warning from Windows not to use this utility with 2007 Office system products, which are what I have.
*“Download Quicktime Standalone Installer”*
I have no interest in Quicktime and only have it because it is apparently bundled with iTunes. Still, I tried this and it did not fix the problem. (BTW, Quicktime still works fine.)
*“Disable other conflicting software”*
I used MSCONFIG to try to troubleshoot conflicts. First, the instructions in article 305415 indicate that the following two items will be under the "startup" tab: "iTunesHelper" and "qttask." These were not listed. Second, when I clicked the "services" tab and selected "hide all microsoft services," there were 25 items still listed, which seems not right to me. I did not proceed here because I was concerned about causing some disaster.
If anyone has any insight here and would be willing to share it, I would greatly appreciate it!
PS--is there a way to copy and paste the list of startup programs so that I can print them and review them one by one? Thanks!

+But before all of that, I wanted to note that I created a new user account and was able to access iTunes that way.+
Up until now you've been working through techniques for troubleshooting System-wide problems. But that fact you relate about the user accounts indicates that you've got a user-account-specific problem, and the troubleshooting techniques are different for those.
In your normal user account, try the techniques listed under "User-specific Troubleshooting" in the following document:
