Hello,
Sorry for my late answer, this is not a bug ...

"Drivers - Hyper-V - Controller" is needed for "Accessories - Disk Image Burning Tool" : in other words, if you don't remove "Accessories - Disk Image Burning Tool", WinReducer will automatically protect "Drivers - Hyper-V - Controller", otherwise "Accessories - Disk Image Burning Tool" won't work !
Have a good day !
