New problems with opening files through the context menu in Windows 7.

1. Notepad++ is closed (portable)
   Select several files and open them through the context menu in Windows 7, as a result Notepad++ will open only one file.

2. Notepad++ is open (portable)
   Select several files and open them through the context menu in Windows 7, as a result Notepad++ will not open any file at all.

Checked on a virtual machine for Windows 10, there are no such problems with Notepad++ (portable)

For many years I have been adding Notepad++ to the context menu using this batch file, and it always worked very well until I upgraded to version 8.9.9-8.9.9.1 (portable)

For everyone who is not aware, I remind you that a portable version of the Notepad++ file NppShell.dll has never existed.
