令我煩惱的是,Windows 10 在許多圖片檔案(例如 .png 和 .jpg)的上下文選單中都有標題為「向右旋轉」和「向左旋轉」的項目。我希望擺脫所有圖像文件類型的這些,但我需要能夠以自動化的方式做到這一點。我知道我可以透過使用一些外部程式或可能更改註冊表編輯器中的某些權限來手動刪除這些鍵,但正如我所說,它需要自動化。此外,每當我重新啟動電腦時,這些上下文功能表條目都不應返回。
在登錄編輯器中,我發現:
Computer\HKEY_CLASSES_ROOT\CLSID\{FFE2A43C-56B9-4bf5-9A79-CC6D4285608A}
似乎是儲存這些上下文選單整體的位置。所以我嘗試創建一個 .reg 檔案來自動刪除此密鑰:
Windows Registry Editor Version 5.00
[-HKEY_CLASSES_ROOT\CLSID\{FFE2A43C-56B9-4bf5-9A79-CC6D4285608A}]
但無濟於事,因為運行 .reg 檔案絕對沒有任何作用。即使我嘗試手動刪除該金鑰,Windows 也會出現以下錯誤:
這顯然沒有幫助。然而,根據我所讀到的內容,即使人們確實設法刪除了這個密鑰,Windows 也可能會在電腦重新啟動後立即將其恢復,這絕對不是這裡的目標。
所以我想在這裡完成兩件事:
使用某種腳本(不一定是 .reg 檔案)來自動刪除這些「向右/向左旋轉」上下文功能表條目。
確保他們永遠不會回來。
這可以做到嗎?如果是這樣,怎麼辦?
答案1
首先,您無法在不更改所有權的情況下更改或刪除該密鑰,因為它使用可信任安裝程式證書。改變使用並不困難登錄編輯器:右鍵單擊該鍵,單擊權限...,然後按一下Advanced
按鈕。將自己設置為所有者,並且替換子容器和物件的擁有者。然後編輯權限,以便您可以刪除該金鑰。
期望在每次主要的 Windows 更新中,原始所有權和金鑰都將重新聲明。
如果你想腳本改變,你需要使用電源外殼這樣做。下面的程式碼來自上面的鏈接,我沒有測試過。

這是一個簡短的過程。從下面給出的鏈接下載 SetACL 工具。在記事本中複製以下命令並將其另存為批次檔(.bat 或 .cmd)。
@echo off
set X="HKCR\CLSID\{FFE2A43C-56B9-4bf5-9A79-CC6D4285608A}"
%~dp0\SetACL.exe -on %X% -ot reg -rec cont_obj -actn setowner -ownr "n:Everyone"
%~dp0\SetACL.exe -on %X% -ot reg -rec cont_obj -actn ace -ace "n:Everyone;p:full"
reg delete %X% /F
pause
將批次檔和 SetACL.exe 放入同一資料夾。運行批次文件作為管理員。註冊表將被刪除。

您可以刪除一些管理員應具有完全存取權限的註冊表項,這些註冊表項構成對您提到的註冊表項的引用(每種適用的映像檔類型都有一個):
