Again, I offer my thanks for your help. I think I have solved the problem! I was reluctant to do all kinds of installs and uninstalls, without knowing what might be causing the problem. Your comment that the problem might be due to something I ran, made me start to look at some of the software I have that could be interfering with Windows 7, focusing on problems that run all the time in background. I did a Google search with just a few words, such as "PerfectDisk" and "Avast." Bingo! I found out from one post that there is a conflict between these two programs. There was a suggestion to put the Avast folders into an exclusion file in PerfectDisk. I did that and the icons have not disappeared for three days in a row, so I am convinced now that this was the problem. There was also an indication in the posts I read that the developers of both programs have been communicating to try to fix the conflicts.
For at få dine ikoner igen, skulle det ikke være nødvendigt at genstarte. Hvis du går i en kør kommando, så prøv at skrive explorer.exe
Så burde de komme tilbage
