How to Make PDF default Adobe Acrobat X Pro instead of Adobe Reader DC

Question

Some stupid website I use regularly forced me to "update" my Reader to Adobe Reader DC, but I have a fully licensed full version of Adobe Acrobat X Pro. Unfortunately, I cannot seem to find any place to reset my default for opening PDF files back to Adobe Acrobat X Pro. When I go into Windows 10 settings and select Pro as the default instead of Reader DC, it does not change the icon, nor does it change the default action. I cannot uninstall Adobe Acrobat Reader DC because of websites I use that require it (unless you know of some way to trick them into beliving X Pro is OK), but I can't stand having PDF's opened with the Reader by default, and then I can't do anything with them, so need to manually open them from within X Pro. Any ideas or solutions would be a HUGE help. Thanks in advance for any help!!

Same the PDF Handler is grayed out when Reader DC is installed. After uninstalling DC it came back as an option. Without DC installed Acrobat X pro works fine and one can change via normal "open with" options to make PDF files default to different things and back. Once DC is installed, it somehow overrides and blocks all the older Adobe X pro software, though the X pro software still opens fine on its own via the now icon missing shortcut or exe open, with both installed. DC blocks it from becoming a default application.

In the previous version of windows I edited the registry myself. I was hoping for a simple windows driven method, but it appears Adobe made it worse by blocking all windows based options with DC and forcefully blocked backwards compatibility therein. I’m sure Adobe has a made up excuse as to why, which just per the other comment about new licenses means they just want more money of course.

I found a way that worked for me. Be very careful when modifying your registry. Like a dump truck on the interstate, I am not responsible for broken Windows.

Run regedit as an administrator.
Find the HKEY_CLASSES_ROOT\Acrobat.Document.DC\shell\Open\command key.
The value of the (Default) value you see on the right will be something along the lines of
"C:\Program Files\Adobe\Acrobat DC\Acrobat\Acrobat.exe" "%1"
which you will want to change to point to your Acrobat Pro X or XI install instead. It should look something like this:
"C:\Program Files (x86)\Adobe\Acrobat 10.0\Acrobat\Acrobat.exe" "%1"
Where the quotes are positioned and the "%1" are very important. Be very careful with your modification.
Close regedit and try double clicking a PDF now. It should open in Acrobat Pro.
