Detailed description：
I can't turn on the Core Isolation - Memory Integrity.
I only saw this error after doing Windows update recently and using Mumu Player which is a PC Emulator by Netease.
I contacted Microsoft Support and there is still no update fix for it. I saw online that the usb2ser.sys by MediaTek is from Asus. Need help.

I found this about Mediatek usb2ser.sys @Falcon_ASUS @RAJU.MSC.MATHEMATICS


Also the usb2ser.sys still needs for communications and CDC control so shouldn't be removed.

You finally removed  Mediatek usb2ser.sys driver, now the memory integrity is turned on, right?
On 14th October 2022, in my reply, I said you should remove the Mediatek driver, But you said i never do that.
Microsoft's official page mentioned this Usbser.sys

@RAJU.MSC.MATHEMATICS Yes my Core Isolation is turned on now. I also forwarded the steps I did to Microsoft support engineers. The old driver that I removed from mine is the Mediatek usb2ser.sys which is different from the one mentioned above usbser.sys sorry for the confusion, thanks again for trying to solve my core isolation issue!

Thanks for your reply. If you get any other issues, I will try to give to steps without reinstalling windows.
