[Chrome] disable "停用開發人員模式擴充功能" warning

因為裝了 UpNext extension ( from github) , 所以出現了這個提示。

實在很惱人，在看了低調一點的辦法後，發現我根本沒有 gpedit.msc 啊~

(因為我是 notebook windows 10 , 好像要 windows 專業版才有這個功能)

但，深深被 geek 精神影響的我，內心其實也微微的排斥這種方法的，太 win 的方式不適合我 (被踢

既然插件是從很 geek 的 github 載下來的，解決方法也要很 geek 的從 stackoverflow 找啊 (其實是 google 找到的

不過試著用英文搜尋看看真的很重要，不要被中文思維所局限了，所謂視野開闊，就從英文搜尋開始～

so 上的 hacker 果然厲害，直接從 dll 下手，而且還是用 bat 檔改，恩，更新日期還很新(Jan 14, 2017)，太棒了。(傳送門戳我)

沒有摸過 bat , 只有摸過 linux 的 script , bat 也是看懂了一些，這位仁兄似乎是直接開檔改一些值，太狂啦~

講一下步驟

Save the code below to DevWarningPatch.bat somewhere

(on the Desktop, for example or in the folder with chrome.dll)

將下列 code 存成 DevWarningPatch.bat (注意副檔名)。

不會改副檔名自己找辦法(有些人可以直接用重新命名改)，或用記事本存 .txt 再右鍵進內容改。

儲存的位置不限，可以是桌面，或是 chrome 的系統夾。

我才不會說 geeker 都是用 vim 呢 ( 謎 : geeker 才不用 windows )

註:其實檔名沒那麼重要，但，尊重作者。

Exit Chrome.

Or let the script close it including its hidden background processes.

關閉 chrome , (可以直接關閉他，或讓 script 關閉他) ，包含 chrome 在背景運作的程序都要關閉。

( 這，我就直接右上角按 x 而已)

Rightclick the batch file and run it as administrator: it will find & patch all applicable chrome.dll

Alternatively you can drag'n'drop chrome.dll onto the batch file

右鍵點擊 bat 檔，並以系統管理員身分執行，他就會為 dll 上 patch ,

或者你可以將 chrome.dll 拖曳到這個 bat 檔上。

完成提示圖

以下 bat 僅為參考，最新更新以 so 為主。( the bat file here )
