Unable to change Default Apps by File Type

Unfortunately, I already have it disabled and have had it that way for a long time.

Disabled in 'Run without permission'? Well, it worked when I tested it with Reader XI which I got direct from Adobe here...
https://get.adobe.com/uk/reader/otherversions/

In my installation show up and run without permission, it just shows up in the all add-ons section.
It may work for you but it obviously doesn't work for me.
See screenshots below:

It may work for you if you uninstall Reader DC and install Reader XI, that's what I used in my tests. I got it from Adobe here...

Guess what? After I uninstalled the Reader DC and installed Reader 11 everything is exactly the same as it was previously! Nothing at all changed and I still have the original problem. I still don't have Adobe showing up in the run without permission section and everything else looks exactly the same. The only difference is that when I do open a PDF file from my computer it opens up and Reader 11.

That's a pain! Well, if you'd like to try Reader X (the one in my first screenshot with the 'display in browser' tick-box) I've found it for you on Adobe's ftp server.

ftp://ftp.adobe.com/pub/adobe/reader.../10.1.4/en_US/

I certainly agree with the problem being a pain! Guess what, same thing after uninstalling Reader 11 and installing Reader 10!
The only thing different making this change was it Adobe showed up in the add-on section as being new and I had to disable it.
I'm getting lots of good opportunities to measure my boot speed however, fortunately I have an SSD, i7 processor and 32 GB of RAM so boots are quite quick.

I'm about ready to accept it as something I'm stuck with even though I don't like it.

Butr doesn't your Reader 10 now have the 'display PDF in browser' tick-box? The one I used in post #15 to change the behaviour in IE?

You'll also have to edit the Preferences > Updater to 'do not download or install updates automatically' else you may soon be back to the latest version.

No it has the same screen as I posted earlier, it does not have "display in browser" checkbox. I'm using iObit on installer and using the power clean function to ensure everything is removed from each installation before install the next one. I'm also rebooting between the uninstall and the next installation. I'm thinking that somehow Microsoft has taken over some of the Adobe functionality with 1 of their recent updates.

That is really odd. Something on your machine is remembering the newer version of Reader. Do you have any other Adobe products installed that may include another copy of the Reader? The full version of Acrobat, perhaps?

On my test machine installing Reader XI let me change the IE behaviour in...



...and installing Reader X 10.1.4 from the ftp link I gave you has the tick-box in...

I don't have any other Adobe products and as I said I ensure that I had complete removal of one version, then rebooted and then installed the next one in every case. I'm sure nothing is left over.

I'm running Windows 10 Prox64 and up on version 1709 OS build 1629.64.
