解決方法如下：
如上圖，電腦用著用著，左下角的Cortana小娜搜索欄無端端變成了白色，看著忒難受，找了很多地方都說解決方案是改語言，然后重啟之后改回來。
方法確實(shí)是有效，可是過了一小陣子，重新用搜索功能的時(shí)候又變成了白色。
1. 將[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Search\Flighting\0\WhiteSearchBox]的Value字段從1改成0 ；
（搜索欄主體已經(jīng)不是白色，但搜索欄上端邊緣還有一小圈白色。）winwin7.com
2. 將[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Search\Flighting\0\SearchBoxBorderThickness]的Value字段從1改成0。
之后重新啟動(dòng)Windows資源管理器或電腦即可恢復(fù)小娜搜索框顏色
還有一個(gè)方法：應(yīng)對(duì)注冊(cè)表丟失的問題
1、復(fù)制以下藍(lán)色代碼到記事本中，然后另存為reg文件；

2、雙擊導(dǎo)入注冊(cè)表，之后重啟Windows資源管理器即可解決。
Win10小娜搜索框的顏色變成白色怎么辦?不要著急，按上面小編分享的兩個(gè)方法操作就可以解決了。
