"Explorer.EXE" popup

[Huldrich]

Hello, I changed my HDD where I have the partitions D, E and F. On F I have the temp folder instead of c:\windows\temp, which I defined in "Environment Variables". After cloning the disk, I set it to c:\windows\temp but then I realized that an app didn't work anymore. So I reset the variables tmp and temp back to F:\temp, which helped. However, after that I get twice a void popup box entitled "Explorer.EXE" every time I start the PC and I have to click on OK otherwise the startup does not resume. I searched the registry but did not find anything that I could do. Any suggestions to get rid of this popup?
