What is Windows Defender?
It is software whose mission is to detect viruses. This tool was previously known as Microsoft AntySpyware. This software has antivirus and antispyware capabilities. Plus, it installs natively with Windows 10 installation and is completely free.
Although it is known as a result of integrating into Windows 10, it is available from Windows Vista. The tool has been significantly updated since then, to be a quality and effective antivirus.
Microsoft describes Windows Defender as "the first line of protection." This software includes items such as Windows Passport, FIDO authentication and support, Device Guard, firewall, credential storage in a secure 'container', and other security features.
Solutions to "Windows Defender cannot be activated"
Remove third-party antivirus
Although we think that Windows Defender is not working, it is constantly operating in the background. Installing a third-party antivirus with Windows Defender running can generate several conflicts.
It could be that we no longer have a third-party antivirus, but in the past we did. To eliminate these conflicts Microsoft recommends a number of apps that erase everything, removing any trace.
Clean Windows startup
Many Windows functions and tools are hidden, but they offer us many possibilities. One of these tools is the 'system configuration' tool. We must carry out the following steps:
- Start it by opening the 'Start Menu', looking for the 'System Settings' and running it
- We go to the services tab
- Any of these services that are not from Microsoft, we can deactivate it without problems
- We recommend disabling them all
We can also choose to clean the start from the task manager. To do this we will follow the following steps:
- We right click on the 'Taskbar'
- Click on the 'Task Manager'
- Let's go to the 'Home' tab
- It shows us all the applications that run when we start the operating system. We can disable all that we consider.
Restart the Security Center service
If you have not been able to solve the problem, calm down, it may be that the Security Center service is failing. To activate it again we must follow the following steps:
- We put in the Windows 10 search engine: Services
- We click on this tool
- We are looking for the 'Security Center' service
- We right click and we give 'Restart'
