很多人不知道的是，從Windows 10開始，直到現在Windows 11，Windows系統默認的看圖App都存在一個重大缺陷——色彩管理。從Windows 10開始，系統默認的看圖App使用UWP構建，色彩管理非常糟糕，在廣色域屏幕上，看一張SRGB色域的圖片，分分鐘出現飽和度爆表的情況，顏色過份鮮豔以至於辣眼。UWP發布這麼多年，色彩管理的問題依然懸而未決，實在很不應該。

Windows 10開始，包括照片App在內的UWP應用無法正確進行色彩管理，圖為Chrome和舊Edge的對比

在Windows 7中，就不存在這樣的問題。Windows 7系統的照片查看器使用Win32構建，對色彩管理有著比較好的支持。於是問題來了，在Windows 11中這個Windows 7版的照片查看器默認是找不到的，要如何重新將它找回來？可以試試下面的方法！

首先，我們打開記事本，將以下文本複制進去。

接著，點擊“文件”-“另存為”，將其另存為後綴名為“.reg”的註冊表文件。

然後，雙擊運行這個註冊表文件，向註冊表導入信息。

導入後，Windows 7版本的照片查看器其實就已經回來了。右鍵點擊圖片文件，選擇打開方式，就可以找到經典的“照片查看器”了！

最後想說的是，平心而論，Windows 11自帶的看圖App界面更好看，動畫更流暢，對觸控的支持也更好。但偏偏在色彩管理這樣的基本功上，卻完敗給了Windows 7的照片查看器，作為一款看圖工具，連顏色都無法正常顯示，顏面何存？UWP糟糕的色彩管理已經不是一兩天的事情了，微軟遲遲沒有解決這個問題，實在令人感到失望。
