Error Mounting disk image

When I use the “mount-diskimage” to mount a disk image (.ISO) return an error :

Mount-DiskImage : The parameter is incorrect.

+ CategoryInfo          : InvalidArgument: [MSFT_DiskImage:ROOT/Microsoft/.../MSFT_DiskImage] [Mount-DiskImage], CimException
+ FullyQualifiedErrorId : HRESULT 0x80070057,Mount-DiskImage

Get-diskimage and Unmount-diskimage also return the same error
In windows 8.1 ,I don’t have this problem, I’m getting This error is only in windows 10 build 10074.

It’s a Beta version of the OS, report it to MS

OK, tha’s what I’m going to do.
