Transferring iCloud photos mixes up dates

I've been trying for years now to transfer my iPhone/iCloud photos to my PC.

The problem is, whenever I try to do so, the real dates of the photos weren't transferred properly.

There is a significant difficulty with photos saved from WhatsApp, and other untraceable date-mismatching.

I thought I found a solution now, by approving this:

Letting iCloud place its photos in this folder:

After a few minutes, the folder was filled with all the photos:

As seen, the photos aren't downloaded on the computer, but rather still stored on the cloud.

The problem now is, some photos have different values for: 'Date', 'Date created', and 'Date taken', as follows:

The values for 'Date' and 'Date taken' are the real dates, as opposed to 'Date created'. The thing is that once I download some of these out-of-sync photos, the 'Date created' value replaces 'Date', and 'Date taken' is completely erased.

Is there any solution to this problem, and in general, any simple way to transfer the photos to my PC while keeping the proper dates?
