Windows 10: Windows Defender crashes on startup after uninstalling McAfee?

When I bought my new PC, MacAfee was preinstalled. Seeing that Windows Defender was good enough, I uninstalled McAfee. I still can't open Windows Defender, but still receive notifications about automatic scans. sorry about the GIF quality, I couldn't attach a video

McAfee and Windows Defender

When a different antimalware protection product is installed, Windows Defender is disabled to make sure the two products do not interfere. In other words, McAfee tells Windows that McAfee is now protecting the system, and Windows therefore turns off Windows
Defender.

There should be an uninstall entry for McAfee if you'd like to remove the trial. Go to Start | Settings | System | Apps & features to find McAfee's entry. Once you click on it, there should be an Uninstall button that'll kick off the uninstall steps.

how do I get Windows Defender working after I uninstall McAfee?


What would suggest I do, McAfee came pre installed on my HP Laptop. My "free" subscription ends in a few days and I noticed that my Windows Defender does NOT work. It is grayed out because of McAfee as I have learned reading other posts on this board.
Other AV programs have this effect on Windows Defender in many cases.
I guess my question is how do I get Windows Defender working after I uninstall McAfee?
Thanks

Soon as you remove McAfee, Windows Defender should come back on ....they won't run at same time.
