Lets say, I belong to Administrators in Windows 10 and I want:
- I.
- All other existed users.
- Users not created yet.
When anyone from the above list press “enter” on a PDF file, then PDF opened with SumatraPDF.
Until now:
I create a key HKCR/.pdf with default value SumatraPDF.
Then I create a key HKCR/SumatraPDF/Shell/open/command with default value "C:Program FilesSumatraPDFSumatraPDF.exe" "%1"
But it is not so easy.
There is some an annoying key in HKCR/SOFTWARE/Microsoft/Windows/CurrentVersion/Explorer/FileExt which makes things difficult.
Can anyone explain the logic of registering file extensions on Windows 10?
PS: Edge usually capture PDF file extension but not if you deny write for everyone.
