agree. actually this issue also happend on Emacs 29.2

I tested this version of Emacs 29:
http://mirrors.syringanetworks.net/gnu/emacs/windows/emacs-29/emacs-29.1_2.zip

Yes, I can confirm that the .emacs.d folder exist.

When I try `M-: (w32-shell-execute nil "~/.emacs.d/")`, it works as
expected. the .emacs.d folder will shows in the Windows Explorer.

I also try `M-: (w32-shell-execute "open" "~/.emacs.d/init.el")`,
it aslo works as expected, the init.el will be open with the default
notepad editor.


Another infomation about this issue, may be it is related:

I also tried to reproduce the issue on my other Windows machine with
Windows 10 and Emacs 30.

At the fist time I tried it, every things is working as expected. I also
can not reproduce the issue on that machine.

But after I installed the PowerToys  by
`winget installMicrosoft.PowerToys`, and luanch the powertoys then I can
reprodue the issue. Maybe the issue is related to PowerToys?

About the PowerToys: https://github.com/microsoft/PowerToys

But I uninstall the PowerToys, then restart that machine, the issue
still existed.


Best regard,
