Hi @曦 刘,
Welcome to Microsoft Q&A!
It is noted that Internet Explorer 11 has been permanently disabled through a Microsoft Edge update on certain versions of Windows 10.
You can see the instruction and try the following steps to open Internet Explorer 11:
select Start , and enter Internet Explorer in Search . Select Internet Explorer (Desktop app) from the results.
If you can't find Internet Explorer on your device, you'll need to add it as a feature. Select Start > Search, and enter Windows features. Select Turn Windows features on or off from the results and make sure the box next to Internet Explorer 11 is selected. Select OK, and restart your device.
You can also refer to the similar issue.
Sincerely,
Anna
