Yes, that is true, but I exported the original code from XP registry, and it works there just fine. I am surprised it works without Expand_SZ (EDIT: I looked at the original registry, and it was Expand_SZ. It appears that the program I am using called Mitec Registry Viewer has a flaw, or rather, only exports REGEDIT4 format. Next time I will mount the hive in Regedit!) From what I read, I concluded they were an annoyance as well. Your custom keys didn't work either. Absolutely nothing happens. I am using Windows Embedded Standard 7, but I think it should be the same as Win7. Below are the default registry settings (no modification), in WES7. Please verify if your mod works in Win7!
