Yes, you can also save the icon positions without Admin rights. Please use the DesktopOK version 1.75 and higher.
If there are problems with the storage (save) of the icon layout in the "DesktopOK.ini", you can optionally rename the DesktopOK.exe in DesktopOK_reg.exe.
In this case, the Iconlayout and the settings will be saved in the registry. Under: "HKCU/Software/SoftwareOK.de/DesktopOK"
