Hi Ziggy, I use this batch to remove it from the context menu (simply create a .bat file, paste these lines in and run it):

@echo off
cls
echo Creating the REG file on your Desktop…
timeout /T 2
@echo Windows Registry Editor Version 5.00>> “%UserProfile%Desktopremove_3dprint_context.reg”
@echo >> “%UserProfile%Desktopremove_3dprint_context.reg”
@echo [-HKEY_CLASSES_ROOTSystemFileAssociations.bmpShellT3D Print]>> “%UserProfile%Desktopremove_3dprint_context.reg”
@echo >> “%UserProfile%Desktopremove_3dprint_context.reg”
@echo [-HKEY_CLASSES_ROOTSystemFileAssociations.jpgShellT3D Print]>> “%UserProfile%Desktopremove_3dprint_context.reg”
@echo >> “%UserProfile%Desktopremove_3dprint_context.reg”
@echo [-HKEY_CLASSES_ROOTSystemFileAssociations.pngShellT3D Print]>> “%UserProfile%Desktopremove_3dprint_context.reg”
echo Running the REG file and removing “3D Print” from the context menu…
timeout /T 2
regedit /s “%USERPROFILE%Desktopremove_3dprint_context.reg”
echo Removing the created REG file…
timeout /T 2
pause
del /f /q “%USERPROFILE%Desktopremove_3dprint_context.reg”
EXIT

And you can use this to add it back:

@echo off
cls
echo Creating the REG file on your Desktop…
timeout /T 2
@echo Windows Registry Editor Version 5.00>> “%UserProfile%Desktopadd_3dprint_context.reg”
@echo >> “%UserProfile%Desktopadd_3dprint_context.reg”
@echo [HKEY_CLASSES_ROOTSystemFileAssociations.bmpShellT3D Print]>> “%UserProfile%Desktopadd_3dprint_context.reg”
@echo @=”@%SystemRoot%\\system32\\PrintDialogs3D.dll,-5039″>> “%UserProfile%Desktopadd_3dprint_context.reg”
@echo >> “%UserProfile%Desktopadd_3dprint_context.reg”
@echo [HKEY_CLASSES_ROOTSystemFileAssociations.jpgShellT3D Print]>> “%UserProfile%Desktopadd_3dprint_context.reg”
@echo @=”@%SystemRoot%\\system32\\PrintDialogs3D.dll,-5039″>> “%UserProfile%Desktopadd_3dprint_context.reg”
@echo >> “%UserProfile%Desktopadd_3dprint_context.reg”
@echo [HKEY_CLASSES_ROOTSystemFileAssociations.pngShellT3D Print]>> “%UserProfile%Desktopadd_3dprint_context.reg”
@echo @=”@%SystemRoot%\\system32\\PrintDialogs3D.dll,-5039″>> “%UserProfile%Desktopadd_3dprint_context.reg”
echo Running the REG file and adding “3D Print” to the context menu…
timeout /T 2
regedit /s “%USERPROFILE%Desktopadd_3dprint_context.reg”
echo Removing the created REG file…
timeout /T 2
pause
del /f /q “%USERPROFILE%Desktopadd_3dprint_context.reg”
EXIT

Hope it will help and won’t come back, let me know if you need more help. :)
