My PC with Windows 10 Enterprise 2016 LTSB v.1607 installed, automatically restarted for an error (I don't remember the error, I just remember a blue page in Windows style with a sad emoticon face). When the PC restarted, Windows defender was disabled and I'm not able to turn it on. The error is:
Windows Defender is Turned off by Group Policy. To protect your computer against harmful or potentially unwanted software, contact your system administrator to enable Windows Defender via group policy.
I've tried all the following things:
- Delete the value in the
HKey_Local_Machine\Software\Policies\Microsoft\Windows Defender(I've not this key because my version is older than v.1703).
Local Computer Policy > Administrative Templates > Windows Components > Windows Defenderthe option

Control Panel > Action Centerunder the voice
Windows FirewallI can read:
For your security, some settings are managed by your system administrator, but I'm the administrator.
How can I turn on Windows Defender?
