General and Security Updates are either GDR only or GDR+LDR you can easily install those normally (without LDR mode) to get GDR branch and you may include/count Platform & Platform Updates & IE11/10 into this Hotfixes however, some are LDR only, and the rest are GDR+LDR managing those will be tricky for you anyway, if you want to only have GDR updates, it's better you stick to what Windows Update offers or you may install "General, Security, Platform, Platform Updates, IE11 Cabs, IE11 Updates, WUClient" in normal mode, then go to Windows Update and see what else it offers and download them
