How to disable blur in Windows 10's Photo Viewer when zooming (or alternative programs)?

I work on pixel art stuff so this always bothers me. Windows 10's default imageviewer does this to the images:

and while it's great for some types of images it doesn't work with what I usually have to look at. Something that bothers me is that when I close the program it shows the image without blurriness for a split second, so I wonder if I there's a way to completely disable the feature. Good program alternatives are also appreciated.

Solution 1:

The default Windows 10 app for viewing pictures is Photos. On the other hand Windows Photo Viewer is an older app, which I - and many others - preferred. You can still enable this program on Windows 10 to get the old behaviour back. Here's A tutorial on how to do it, although it requires some registry edits, which always seem a bit scary. It worked perfectly for me though. See comparison below:

Blurry - Photos

Not blurry - Windows Photo Viewer

It also offeres greater maginification and seems more responsive / is quicker to open

Solution 2:

You could give 'Emulsion' a try: https://arturkovacs.github.io/emulsion-website/

It's fast and minimalist with entirely optional anti-aliasing.

Edit: Now I'd recommend ImageGlass instead. A more fully featured and customizable image viewer that also do not apply any anti-aliasing: https://imageglass.org/
