I know that in XP you could go into msconfig and under startup items turn setrefresh.exe off. See if that is available under Windows 7. I can't verify myself yet due to my work pc being XP. I also found this to try:
To enter clean boot mode on a computer, follow these steps.
1. Click Start, type msconfig in the Start Search box, and then press ENTER.
If you are prompted for an administrator password or for a confirmation, type the password, or click Continue.
2. On the General tab, click Selective Startup.
3. Under Selective Startup, click to clear the Load Startup Items check box.
4. Click the Services tab, click to select the Hide All Microsoft Services check box, and then click Disable All.
5. Click OK.
6. When you are prompted, click Restart.
7. After the computer starts, check whether the problem is resolved.
You'll need to return to normal boot once done and find the item that is causing the problem. Could take a bit so be patient.
