PDF opened in EDGE

[mLipok]

By default Windows 10 opens PDF files in EDGE

Question 1:
How do you check which default viewer for PDF is set in Windows?

Question 2:
How do you check where Acrobat Reader is located?

Question 3:
Do you have any working solution to change the default PDF Viewer to Acrobat Reader?

 

EDIT:
I usually find that kind of thing in Registry so ....
According to 
https://social.msdn.microsoft.com/Forums/vstudio/en-US/630ed1d9-73f1-4cc0-bc84-04f29cffc13b/what-registry-keys-are-responsible-for-file-extension-association?forum=netfxbcl
 

The key should be located somewhere here:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.pdf
HKEY_CURRENT_USER\Software\Classes\.pdf
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.pdf
HKEY_CLASSES_ROOT\.pdf
 

But I can not find a way to check if EDGE is still default viewer.

Hello

1:

With this you can get the program Id based in an extension

Local Const $sCLSID_ApplicationAssociationRegistration = "{591209c7-767b-42b2-9fba-44ee4615f2c7}"
Local Const $sIID_IApplicationAssociationRegistration = "{4e530b0a-e611-4c77-a3ac-9031d022281b}"
Local Const $sTagIApplicationAssociationRegistration = "QueryCurrentDefault hresult(wstr;int;int;wstr*);"
Local $oApplicationAssociationRegistration = ObjCreateInterface($sCLSID_ApplicationAssociationRegistration, $sIID_IApplicationAssociationRegistration, $sTagIApplicationAssociationRegistration)
ConsoleWrite("IsObj($oApplicationAssociationRegistration): " & IsObj($oApplicationAssociationRegistration) & @CRLF)


Local $sDefaultPDF=""
$oApplicationAssociationRegistration.QueryCurrentDefault(".pdf", 0, 1, $sDefaultPDF)
ConsoleWrite("$sDefaultPDF: " & $sDefaultPDF & @CRLF)

2:

I can see Install path here

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Adobe\Acrobat Reader\DC\InstallPath

 3:

In windows 7 It's very easy to change default App but Windows 10 It's complex. I wrote a tool (not in AutoIt) to set an App as Default You can use it as base. You can check here.

In Windows 10 you can use:

#include <StringConstants.au3>
Opt("ExpandEnvStrings", 1)
Local $iPDFDefault, $sPDFDefaultExt = RegRead("HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.pdf\UserChoice", "ProgId")
Local $sPDFDefaultExe = RegRead("HKCR\" & $sPDFDefaultExt & "\shell\open\command", "")
    $sPDFDefaultExe = StringRegExp($sPDFDefaultExe, '^"(.+?)"', $STR_REGEXPARRAYMATCH)[0]
ConsoleWrite("Prog ID: " & $sPDFDefaultExt & @CRLF & "Command: " & $sPDFDefaultExe & @CRLF)

Normally I use PowerShell to export file associations from a configured machine.  During image build we import them using PowerShell.  Initially we used Group Policy to import the file associations xml file, however staff weren't able to change the associations, example if they were using Adobe Acrobat rather than Adobe Reader.  If I do need to modify an extension I just export the "UserChoice" key above and use either Group Policy preferences or script to add the key to clients.  We also use the following to stop Edge from hijacking file extensions, using NoOpenWith and NoStaticDefaultVerb (see : https://www.winhelponline.com/blog/edge-hijack-pdf-htm-associations/).

also try to have a look to the Assoc and Ftype console commands as explained here: https://superuser.com/questions/406985/programatically-associate-file-extensions-with-application-on-windows

Thanks to all.

Are there any ways to do this without admin permissions? Writing to that portion of the registry is blocked and Ftype requires admin. I can set the default using the "Open With..." dialog, but I can't do it programmatically?

@seadoggie01 You can check the way to do it in my blog (it's not programmed in AutoIt)

@Danyfirex Oh! Thank you for re-pointing me there, I saw that you found a way, but jumped right over the link that explained how
