In my opinion, this is mergeable. We can improve it on another PR |

Why don't use vector.GetAt(i) here? We are doing it above to extract the manufacturer data.

I think I was a bit confused, and didnt really get the difference. Hence my comment, I will update this with GetAt

The problem here is that this is a vector of GUID structs (not pointers). So you will need to convert the unsafe.Pointer to syscall.GUID (without the asterisk).
I found that this works:
for i := uint32(0); i < size; i++ {
element, _ := vector.GetAt(i)
// element is not a pointer, but a GUID struct. But we cannot convert
// unsafe.Pointer to a non-pointer type, so instead we are doing this:
serviceGUID := (*syscall.GUID)(unsafe.Pointer(&element))
uuid := GUIDToUUID(*serviceGUID)
serviceUUIDs = append(serviceUUIDs, uuid)

I have just applied your changes @jagobagascon
However I am currently unable to test the Windows version, so I will have to trust your suggestion :D

@jagobagascon can you check my code comment ?
I know that the current version work, but I think I can directly cast the element to a GUID pointer ?
I don't have a windows machine with me to test it right now.
