Windows 10: Change default app with regedit or bat

We have a gpo which sets the default app for pdf's, we do not want to change this, except for when a user runs a bat script without admin rights.

I have been trying to make a .bat file that would change the default pdf program to reader with;

ftype AcroExch.Document.DC="C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\AcroRd32.exe" "%1"

(Running this with either cmd (privileged) or .bat does not work)

Users can change default app within the settings of Windows without privileged rights, but they are required a elevated cmd to run the bat script (which does not work).

My last resort would be; to either set default app within regedit (which the gpo hopefully can't change back)

Would be grateful for any help!

How to change default app for file type

'Open With > Choose another app' has three step, in the first it only offers apps registered for that file type. If you click 'More apps' it lists all registered apps regardless of suitability. Both these steps have the tick-box for 'Always use...' in my 18363.752. The third step, if needed, is 'Look for another app on this PC'. The 'Always use...' must be ticked before taking this step if you want the change to stick. However, WMP appears at the second step.

For a quick look at a JPG almost anything (including WMP) is more practical than Photos which on my system takes more than ten seconds just to open a photo. The OP is probably not aware that the Windows Photo Viewer is still available in W10, but hidden away. That's my default viewer for JPG.

How to fix/restore regedit to default?

Hello. I need help how to restore regedit back to its default settings.

I didn't know registry editor is very sensitive that a small change can have huge impact on my computer's functionality.

So here's what happened, I was trying to fix a different issue (can't run a specific .exe file) when I bumped into one of the suggested fix (making some small change in regedit)

So I was trying to follow step from: https://support.microsoft.com/en-ph/help/2688326/can-t-open-exe-files-in-windows-7-or-windows-vista

[*]Click the Startbutton and type regedit in the Search box
[*]Right-click Regedit.exe in the returned list and click Run as administrator
[*]Browse to the following registry key:

HKEY_CLASSES_ROOT\.exe

[*]With .exe selected, right-click (Default) and click Modify…
[*]Change the Value data: to exefile
[*]Browse to and then click on the following registry key:

HKEY_CLASSES_ROOT\exefile

[*]With exefileselected, right-click (Default) and click Modify…
[*]Change the Value data: to "%1" %* (THIS IS WHERE I MADE A MISTAKE)
[*]Browse to and then click on the following registry key:

KEY_CLASSES_ROOT\exefile\shell\open

[*]With openselected, right-click (Default) and click Modify…
[*]Change the Value data: to "%1" %*
[*]Close the Registry Editor and restart your PC

Now, I can't open regedit.exe or any .exe files.

I'm getting the error: Windows can't opent this file

Your help would be greatly appreciated!
