alternative to adobe illustrator for windows

Is Adobe ignoring the issue in order to push Adobe Bridge as an alternative to Windows Explorer? If Sage can do it, then surely Adobe can do it as well. Blaming it on Microsoft is really laughable, considering Adobe's power and say in the industry. I can only speculate that this has nothing to do with Adobe not being able to change it. This works on Apple systems, why not on Windows? Is the Windows community being discriminated against? Adobe needs to be fair and warrant that their apps work properly under Windows 10, just as they do on Apple ecosystems. This has been the cause of so much frustration, as Windows users are basically navigating their file system blind.

I don't buy the argument, that this is a Microsoft issue! If little companies, like the Sage app developer or other 3rd party apps can do it (without the help of Microsoft), then why on earth can Adobe with 144.000 employees not manage to finally display thumbnails of all its app files natively in Windows 10? It works for PDFs, why not for PSD, AI aso?

Not sure I understand why Adobe PDF files WILL magically show up as thumbnails under Windows 10 / Windows Explorer, but for any other Adobe app, thumbnails will not show up natively! Is PDF not a proprietary format as well?
