Windows 10: How to remove MS Defender devices?

I did a factory reset of my phone several times. Apparently, after the reset and adding MS Defender app, each time added another instance of my phone to the list of devices and I have hit the limit of devices for Defender. Now I can't get into Defender on the phone to get to the Dashboard to remove the extra devices.How can I remove them? Can I do this from the web? I tried on the PC, but the MS Defender was replaced with Windows Security and I don't see any place to manage the devices.Now what?

:)

 

Remove Devices

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you are facing issues while removing the device from your Microsoft account as it keeps popping back after removing.



It could be possible that the device was using OneDrive with the same Microsoft account and that might be the reason you are able to see the device listed under your profile. I would suggest you to remove the device from OneDrive
and see if that helps.



You can follow the steps to remove the device from OneDrive.

1. Login to
   https://onedrive.live.com.
2. Now on the left hand pane click on PC’s.
3. Now click on the devices that are listed under PC’s and on the right hand side click on
   Remove PC.

If the issue persists, please get back to us with the results of the troubleshooting steps to assist you further.

MS Defender Won't Load After Upgrade to Windows 10 Ver 1511

Attempted every step in document provided by Microsoft

Redirecting

Nothing worked, HOWEVER, the last step is to Delete Conflicting Registry Entries. My registry contains one of the entries listed (MsMpEng.exe) however, REGEDIT could not delete this entry as I was directed.

Problem still exists; as soon as I start MS Defender, it stops.

Any further suggestions?

 

Unable to Remove Exclusions from Windows Defender

Thank you for posting back. If you trust a file, file type, folder, or a process that Windows Defender Antivirus has detected as malicious, you can stop Windows Defender Antivirus from alerting you or blocking the program by adding the file to
the exclusion list. It seems that it was added automatically. We suggest that you follow these steps:

• Go to Settings and select Update & security.
• Click Windows Defender.
• Look for Exclusions and select Add an exclusion.
• Navigate to the file, folder, or process, and select Exclude this file.

If the steps provided did not work, we recommend that you boot your device to
Safe Mode and redo the process.
