How to fix empty window in Windows Security?

Issue: Hello. I tried to access Windows Security but when it opens, the window is empty. What should I do?

Solved Answer

The issue of the Windows Security window being empty can occur when users go to the “Security at a glance” page and find that it shows up empty. This problem may prevent users from accessing critical security settings and features such as Windows Defender Firewall, Device security, App and browser control, and others.

Users may be unable to check their security status or manage security settings, exposing their devices to malware and other security threats. The empty window in Windows Security may also display error messages such as:

Page not available

Your IT administrator has limited access to some areas of this app, and the item you tried to access is not available. Contact IT helpdesk for more information.

or:

Threat protection has stopped. Restart it now.

Depending on the cause of the problem, there may be several possible solutions. To resolve the issue, some users may need to restart their devices or update Windows. Others may need to restart the Security Center service or reset the Windows Security app. Third-party antivirus software or other security programs may conflict with Windows Security in some cases, requiring users to uninstall or disable these programs to resolve the issue.
