On windows 10, clang-format.el is not obeying .clang-format but it follows _clang-format file from the project Repository.

So I have this is my init.el

    (use-package clang-format
      :init
      (global-set-key (kbd "C-c r") 'clang-format-region)
      (global-set-key (kbd "C-c u") 'clang-format-buffer)
      :config
      (setq clang-format-style-option "file")
      )

And this in my .clang-format

    BasedOnStyle: Google
    Language: Cpp
    Standard: Cpp11
    Cpp11BracedListStyle: true
    IndentWidth: 4
    ColumnLimit: 100
    BreakBeforeBraces: Linux
    AlignAfterOpenBracket: Align
    AlignConsecutiveAssignments: true
    AlignOperands: true
    AllowShortFunctionsOnASingleLine: Empty
    DerivePointerAlignment: false
    PointerAlignment: Left

If I make a _clang-format in any Repository or project directory, then clang-format obeys that file, but It never follows .clang-format file from my home directory , any reason why ?

Just so you know, this repository is the wrong place to report errors as it contains a copy of the official elisp integration code. Furthermore, the problem is within the tool, not the elisp code. The right place to submit bugs to is https://bugs.llvm.org/.
