Windows Photo Viewer in Windows 10

[handrawn]

windows photo viewer is a dll not an app, and in current clean install windows 10 it is only associated with TIFF files

being a dll file you cannot just [re]associate file types to it in the windows 10 UI, it needs a registry patch to do this; once done you get back the wpv

why would I do this? - because the windows 10 photo app:

does not show alpha
does not loop through the files repeatedly
does not [necessarily] sort in the order the files are in [and the patch restores this in wpv]

but that aside it just does not handle some files well - here is an example of pencil sketch PNG:



I have more pencil sketch references like this than you could shake a forest full of sticks at

cool... not
