Windows Security, commonly known as Windows Defender, becomes the default antivirus and security solution when you install Windows 11. It is one of the most powerful medicines available, and it works in the overwhelming majority of cases.

Nonetheless, one of the most commonly reported issues is that Windows Defender does not launch or perform as intended after an update or at random.

When you try to enable Windows Security, you could get a slew of strange error warnings. It could suggest that you install a new program in order to access the Windows Defender link, for example.

The window appears for a split second before vanishes completely. If restarting your computer does not cure the problem, use the troubleshooting options suggested below. We’ll start by learning how Windows Defender works, then move on to the remedies.

What is the purpose of Windows Defender?

Microsoft’s Windows Defender has nearly caught up with the top free antivirus products by delivering great automated malware protection while also having a minimal effect on system performance and a surprising amount of associated bonus features.1640783741_381_Windows-11s-Security-center-not-opening-Try-these-fixes

Scheduled scans are inconvenient for many users, and there is no protection for web browsers other than Edge or Internet Explorer. A separate password manager and file shredder are also unavailable.

What you see is precisely what you get with Windows Defender. Upgrades do not allow for the enhancement of protection or the inclusion of functionality. When considering the whole Windows Security suite, it includes a firewall, drive-level encryption, and even a gaming mode.

However, it still lacks capabilities such as a file shredder and access to a virtual private network that third-party antivirus companies provide as incentives (VPN).

Furthermore, Windows Defender delivers world-class malware protection, making it a convincing argument for not using a third-party antivirus program to replace it.

Its primary flaws are that some of its defensive actions, such as scheduling scans, are difficult to set up and that some of the associated Windows defenses are only available for Microsoft’s own browsers, both of which are minor negatives.

What should you do if Windows Security in Windows 11 won’t open?

1. Fix the app.

  1. To enter the Settings app, press Windows key + I, then choose Apps, then Apps & features.1640783741_63_Windows-11s-Security-center-not-opening-Try-these-fixes

  3. Scroll down to the Reset section, and then select the Repair button. 1640783742_820_Windows-11s-Security-center-not-opening-Try-these-fixes

Allow the Repair procedure to finish before rebooting your computer to guarantee that the changes you made are implemented. By restarting Windows Security, you may see whether its functionality has been restored.

2. Restart the application

Below are two links to antivirus options that are compatible with Windows 11 and will cause little to no issues.

Is Windows Defender up to the task?

Windows Defender has gone a long way in terms of cybersecurity features since its beginnings. Defender used to be terrible, but Microsoft has recently improved it to the point where it is now a decent free antivirus.1640783747_994_Windows-11s-Security-center-not-opening-Try-these-fixes

Defender now incorporates sandboxing and cloud-based malware detection, resulting in improved overall protection and faster detection of threats than ever before.

Microsoft’s Defender is capable of detecting malware files, preventing exploits and network-based assaults, and warning phishing websites, among other things.

It also includes parental controls such as content filtering, use restrictions, and location tracking, as well as simple PC performance and health monitoring.

Users are wondering whether they can depend on Windows Defender alone to protect their PCs now that it has all of these useful features, or if they will need to use a third-party antivirus product in addition.

The reality is that Microsoft Defender is on the brink of competing with third-party Internet security suites more than ever before. However, it is still insufficient.

Defender is certainly a free download, but there’s a reason why internet security packages are so pricey, not least because Microsoft isn’t in the cybersecurity business.
