"Service 'Windows Defender' (WinDefend) failed to start. Verify you have
sufficient privileges to start system services."

What version of Windows?

What other security or antimalware software is in use?

I was never able to get it installed. I just live without it.

Hi All,

I had the same problem when trying to install. Getting error "Service
'Windows Defender' (WinDefend) failed to start. Verify you have sufficient
privileges to start system services."

Mine was due to Spyware or a virus. I got rid of the Spyware by using AVG
and MalWareBytes but was still not able to install Defender (also I had never
had Defender installed on the PC).

Here is how I fixed it:
Searched the Registry for any "Defender" entries. Found an entry under
"HKLM\Software\Microsoft\Windows Defender". When I tried to delete it
(Windows Defender folder) I found I could not due to not enough rights. So I
right-clicked the folder selected "Permissions" for this folder and gave the
Administrator FULL rights (it had only READ). I was then able to delete this
registry folder.

After this I was able to install Windows Defender without any problems. I
believe that the Spyware or virus I got added this entry to the registry to
prevent me from installing Windows Defender.

Hope this fix works for you guys
