Please increase thumbnails / previews in Windows Explorer from 256 to 512 or larger.
Not sure if Microsoft has completly missed the fact that display screen resolutions are increasing globally, yet even the "View > Extra Large Icons" in Windows Explorer with a resolution of 256px is not adequate and more like standard 20 years ago. Microsoft always fames itself for catering to people with disabilities, but these minute thumbnails in Windows Explorer are a real killer for anyone's eyes, with or without disabilities. Please make this change ASAP.
