As suggested in the title, I use a GUI version of Emacs (25.3) on Windows. To be precise : Emacs 25.3.1 X86_64-w64-mingw32
Things were working perfectly but for a few days, some actions related to Dired like
C-x d or
^ take literally ages (it's freezing like 15 seconds) which is a real pain. Emacs startup is fine.
I reinstalled Emacs totally but still get the issue. Any idea what is going wrong ? Thanks in advance.
