When you install Windows 11, Windows Security, also known as Windows Defender, becomes the default antivirus and security solution. It is one of the greatest remedies available, and it is effective in the vast majority of circumstances.

Nevertheless, one of the most frequently encountered concerns has been the fact that, after an upgrade or at random, Windows Defender does not open or function as expected.

Occasionally, when you attempt to activate Windows Security, you may see a slew of bizarre error messages. It may, for example, propose that you install a new app in order to access the Windows Defender link.

The window appears for a brief moment before disappearing without a trace. The troubleshooting techniques listed below should be used if restarting your computer does not resolve the issue. First, we will understand how Windows Defender works, then jump into the solutions.

How does Windows Defender work?

By providing excellent automatic protection against malware while also having a low impact on system performance and a surprising number of accompanying extra features, Microsoft’s Windows Defender has almost caught up with the best free antivirus programs.windows-security-home windows 11 security center not opening

For many users, scheduling scans is too time-consuming, and there is no security for web browsers other than Edge or Internet Explorer. Additionally, there is no standalone password manager or file shredder available.

With Windows Defender, what you see is exactly what you get. Amplification of protection or the addition of features is not accessible as upgrades. When the full Windows Security apparatus is taken into consideration, it includes a firewall, drive-level encryption, and even a game mode.

On the other hand, it still lacks features that third-party antivirus makers include as incentives, such as a file shredder and access to a virtual private network (VPN).

In addition, Windows Defender provides world-class malware protection, which gives a compelling case in favor of not replacing it with a third-party antivirus product.

Its only shortcomings are that some of its defensive activities, such as scheduling scans, are difficult to set up, and that some of the linked Windows defenses are limited to Microsoft’s own browsers only, which are both minor drawbacks.

What to do if Windows Security isn’t opening in Windows 11?

1. Repair the app

  1. Press the Windows key + I to open the Settings app, then go to Apps, followed by Apps & features from where you will be able to access the program.apps-apps-and-feature  windows 11 outlook crashing
  2. Once you are inside the Apps & features window, search for Windows Security in the search bar from the top, and click on the three dot menu next to it followed by Advanced options.windows-security-app windows 11 security center not opening
  3. Scroll down until you find the Reset section, then click on the Repair button to start the repairing process.

It may take some time for the process to finish, so you may need to restart your computer. SFC will automatically find and restore corrupted files and folders. In case that did not help, you can give it a try to Restoro which is much more advanced than Windows built-in tools.

4. Run DISM

  1. Press the Windows + S key to open the Search bar, then type cmd, and right-click on the most relevant result to run it as an Administrator.cmd-run-as-admin avast high cpu windows 11

Continue to be patient until the process is finished. Be advised that the process could take up to ten minutes to finish. Once you’ve completed this step, restart your computer to ensure the changes take effect.

5. Reinstall using PowerShell Command

  1. Right-click on the Start icon then click on the Windows Terminal (Admin) option to open the PowerShell interface.windows-terminal windows 11 security center not opening

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

Is Windows Defender good enough?

In terms of cybersecurity capabilities, Windows Defender has come a long way since its inception. It used to be extremely awful, but Microsoft has lately improved Defender to the point where it is a reasonably good free antivirus.turn-on-defender windows 11 security center not opening

Because Defender now integrates sandboxing and cloud-based malware detection, it provides better overall security while also detecting threats more quickly than ever before.

Detecting malware files, blocking exploits and network-based attacks, and flagging phishing websites are all things that Microsoft’s Defender is capable of doing.

Furthermore, it features straightforward PC performance and health monitoring, as well as parental controls that include content filtering, usage limitations, and location tracking.

Because Windows Defender now incorporates all of these beneficial capabilities, users are questioning if they can rely on it alone to secure their computers or whether they will need to use a third-party antivirus program in addition to it.

The truth is that Microsoft Defender is now more than ever on the verge of becoming competitive with third-party Internet security suites. However, it is still not satisfactory.

Certainly, Defender is a free download, but there is a reason why internet security suites are so expensive, not the least of which is the fact that Microsoft isn’t in the cybersecurity business.
