Windows 10 says Acrobat 9 Standard is my default but continues to open PDFs in Reader DC

[Guest]

I just got a new work computer (Windows 10).  I use both Adobe Acrobat 9 Standard and Acrobat Reader DC.  I've set Adobe Acrobat 9 Standard as my default for PDFs.  It shows as my default on my computer; however, any time I open a PDF it opens in DC.  This is causing me lots of problems as DC isn't compatible with the website I frequently use for my job.  I'm having to uninstall DC just to get my computer to use Standard; however, then I have to reinstall it to get other documents that clients send to me that require Reader.  Also, I've tried right clicking on a PDF doc, clicking Properties, Open With and changing to Adobe Acrobat 9 (which it says it's already using but it isn't) and it STILL opens with DC.  Please help!

Your set-up is problematic. For starters, Acrobat 9 is not compatible with Windows 10. Also, having both Acrobat and Reader of different versions (especially such as old one as 9 and such a new one as DC) is a recipe for problems, especially when it comes to things like integration with the OS. In short, you need to upgrade your version of Acrobat, or remove Reader DC.
