If you change the default web browser to something other than Edge, you can change the default PDF viewer to something else and it'll stick. Windows 10 looks all new and has some new interfaces, but when you get down to it, most of the Windows 7 interfaces are still there, untouched, and they actually work better. I didn't realize the old one still existed. You're right, I am using the new default programs UI in 10. See my thread below - hopefully the best answer for me will solve your issue, too. Don't use the new "Default Programs" crap that 10 defaults to. otherwise I'll be rolling back to Windows 7. If anyone has any ideas on a fix for this, let me know. Today alone I've had 5 different staff members asking me to assist patrons with printing their documents, and it's the same thing every time - they are using Edge, open a PDF, it opens in Edge, doesn't print properly, and I get called in to fix it.This seems trivial, but it's sucking up so much of my time and making me incredibly angry at Microsoft. until Windows 10 Anniversary update came out and made that not work too. There WAS a registry hack that worked for this. Not to mention that it ran faster on our public computers. Or I could just go back to Windows 7, which, you know, worked exactly how I wanted it to and I never had to make any tweaks to. Since I update these computers weekly, I would need to reset the default program to Adobe Reader every single week on every computer.Every time I run Windows update, it restores the default program for PDF files to Microsoft Edge. Except that the program defaults don't stick.I also made sure that Adobe Reader was up to date on all computers. Simple enough, now all PDFs will open with Adobe Reader instead. OK, so we set the default program for PDF files to Adobe Reader.In addition, I just don't care for it when viewing PDF documents.

It simply does not work for our printer - if you open a PDF with MS Edge and try to print, your printed page is usually blank. Microsoft Edge sucks as a PDF document viewer / printer.

I'm very close to just re-imaging my entire fleet of public computers with Windows 7 over this.
