几年前旧版的Chrome可以通过修改Windows注册表禁用

但对于现在的版本那方法可能不好用了

 

Creating a DWord reigstry key called IncognitoModeAvailability, with a Value of 1 for Disabled in the registry folder HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome seems to disable incognito browsing.

or

you can create .reg file by opening up notepad, pasting the below in and saving it as eg incognito.reg. Once saved just double click the reg file to inport it.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome]
"IncognitoEnabled"=dword:00000000
