Windows Defender Security Center Service Missing Windows 11/10

In today’s digital age, cyber attacks are becoming increasingly common and sophisticated. With the rise of malware and viruses, it’s more important than ever to have a strong and reliable antivirus program to safeguard your computer. However, after a malware attack, you may find that the Windows Defender Security Center Service is missing in Windows 11 or Windows 10, which can leave your computer vulnerable to further attacks.

In this article, we’ll delve into the causes of this problem and provide you with practical solutions to restore the missing Windows Security Center Service and get your computer protected again.

The problem arises when you try to enable Windows Defender after a malware attack, and you encounter an error message that says, “Security at a glance – Page not available” when you open the Windows Security settings. When you check the chúng tôi you find that the Windows Security Center Service is missing, which prevents you from enabling Windows Defender.

In some cases, you may see a pop-up that says “You’ll need a new app to open this windowsdefender link” when you try to open the Windows Security settings.

This issue can occur due to several reasons, including a virus or malware that targets the Security Center service or an update that interferes with the service. In some cases, it may be a simple glitch that can be fixed with a restart. However, if the service is missing from the chúng tôi you’ll need to take other steps to fix the issue.

Related issue: Windows 11 Security Tab Missing in Properties

Fortunately, there are several ways to fix the Windows Security Center Service missing issue. We’ll discuss some of the most effective methods below.

One way to fix the problem is to reinstall Windows Defender. Reinstalling Windows Defender can bring back all the necessary services for Windows Defender and Security Center. This can be done with several methods, including running a simple PowerShell command. We recommend trying this method first to see if it resolves the issue. If it doesn’t, try the next solution below.

If reinstalling Windows Defender didn’t resolve the issue, you can restore the Windows Defender Service in Windows 11 or Windows 10 using a registry file. However, before you can import the registry key, you need to start the chúng tôi as TrustedInstaller.

Download Advanced Run from Nirsoft and extract the contents to a folder on your computer.

Under the “Run As” section, select “TrustedInstaller” from the drop-down menu.

Now that you’ve started chúng tôi as TrustedInstaller, you can import the registry file to restore the Windows Defender Service.

Warning: Editing the registry can be risky, and if you’re not familiar with it, it’s best to seek professional help. Before making any changes to the registry, we recommend creating a system restore point or backing up the registry in case something goes wrong. It’s essential to take these precautions to avoid any potential damage to your system.

Download our restore Windows Defender service registry fix.

Extract the downloaded zip file (we recommend extracting it to C: drive).

Navigate to the registry file that corresponds to your Windows version. For example, if you are using Windows 11, select the chúng tôi file.

When prompted for confirmation, select Yes.

Close the Registry Editor and restart your computer.

After restarting your computer, check if the Security Center Service has been restored. If it’s functional again, we urge you to immediately run Windows Update to update Windows Defender to the latest version. Keeping Windows Defender up-to-date with the latest security definitions is crucial to ensure maximum protection against potential security threats.

If the Security Center Service is still not working, you may need to try resetting or clean reinstalling Windows 11/10.

If reinstalling Windows Defender or restoring the Windows Defender Service using the registry file didn’t work, you may need to consider resetting or clean reinstalling Windows 11 or 10 to fix the issue.

Resetting Windows enables you to keep your personal files and settings while removing any apps and drivers that were installed, while a clean reinstall erases everything on your hard drive and installs a fresh copy of Windows. Either of these processes may take some time, but they should fix any issues related to missing Windows Defender or Security Center services.

However, it’s important to note that a clean reinstall should be considered only as a last resort after exhausting all other options. Before proceeding, make sure to back up your files and create a system restore point to avoid losing any valuable data.

In addition to the solutions outlined in this article, we recommend running repair command tools such as SFC (System File Checker) and DISM (Deployment Image Servicing and Management) to ensure that your Windows operating system is functioning correctly. These tools can help fix corrupted or missing system files that may be causing the Windows Defender Security Center Service to disappear.

To run SFC, open the Command Prompt as an administrator and type in the command “sfc /scannow” (without the quotes) and press Enter. The scan may take some time, but once it’s complete, you should see a message indicating whether any issues were found and whether they were successfully repaired.

To run DISM, open the Command Prompt as an administrator and type in the command “dism /online /cleanup-image /restorehealth” (without the quotes) and press Enter. This scan may also take some time, but it can help repair any issues with your system image.

If the Windows Security Center service disappears again after restoring it, it may indicate that your computer is still infected with malware or a virus that is disabling the service. In this case, it’s important to act fast and take additional measures to protect your computer.

Instead of trying to restore Windows Defender, which may not be reliable if the service keeps disappearing, we recommend using a trusted third-party antivirus or anti-malware software to perform a full system scan. It’s essential to choose a reputable software that is known to be effective in detecting and removing malware and viruses.

If the third-party software detects any threats, it’s important to take immediate action and follow the software’s instructions to remove the malware or virus. Once the threat has been removed, you can try restoring the Windows Security Center service again.

We hope this article has been helpful in resolving your Windows Defender Security Center Service missing issue, and we encourage you to take the necessary steps to protect your computer from future threats.

How To Repair An Outlook Pst File That’s Damaged Or Corrupt

Issues with Microsoft Outlook’s Personal Folders File format—commonly referred to as PST—have been a huge problem for years. Microsoft knows that, which is why Outlook comes with a built-in tool called Inbox Repair to help you fix corrupted PST files.

In most cases, simply running a damaged PST file through the Inbox Repair tool should be enough to patch it up. But sometimes, you must take extra action to recover lost items.

Table of Contents

How Outlook PST File Repair Works

Outlook’s Inbox Repair tool is buried deep within the Microsoft Office installation folder on your computer, so you need to do a bit of digging to get to it. Once you’ve located and launched Inbox Repair, all you need to do is select the damaged PST file to repair it. 

Important: Inbox Repair provides an option to create a backup of the damaged PST file. Make sure to select it since you may need a copy to retrieve missing data later on.

1. Completely exit Microsoft Outlook.

Note: The folder paths above apply to Outlook 2024, Outlook 2023, and Outlook 365. If you use an older version of Outlook, you must select the Office15 (Outlook 2013), Office14 (Outlook 2010), or Office12 (Outlook 2007) folder instead.

3. Locate the file labeled SCANPST and run it as an administrator.

4. Use the Browse button to select the Outlook PST file that you want to repair.

If you don’t know the location of the PST file, press Windows+S to open Windows Search. Then, search for it by name and include the .PST file extension. You will see the file location within the search results.

5. Select Start. The Inbox Repair tool will check the PST file for issues. That should take some time.

6. Check the radio button next to Make backup of scanned file before repairing and select Repair.

7. Select OK to finish repairing the PST file.

Open Microsoft Outlook and it should automatically start using the PST file without issues. You will find a copy of the corrupted PST file (with the .BAK extension) in the same location as the repaired original.

Recover Lost and Found Files

Sometimes, Microsoft Outlook’s Inbox Repair tool may end up repairing a severely damaged PST file. Suppose the tool fails to place any repaired items in their original folders or locations. In that case, it will lump them into a Lost and Found folder or a set of folders under the Recovered Personal Folders label. 

You can recover these items by creating a new PST data file in Outlook and moving the contents from Lost and Found or Recovered Personal Folders into it.

1. Open the Home tab in Outlook. Then, open the menu next to New Email, point to More Items, and select Outlook Data File. 

2. Pick the Outlook Data File option and select OK.

3. Specify a location on your computer, enter a name for the new PST file, and select OK.

4. Select the More icon (three dots) to the Outlook window’s lower-left corner and select Folders to switch the Outlook sidebar to Folder List view.

5. Drag the contents within Lost and Found or Recovered Personal Folders into the new data file.

Once you’ve done that, you can choose to remove the Lost and Found folder or the Recovered Personal Folders data file from Outlook.

Recover Additional Items from PST

Suppose you notice any missing items within the repaired data file. if you also can’t find them inside the Lost and Found folder or under Recovered Personal Folders, you can try retrieving them using the backup copy of the original. Basically, you try to import the contents within the file without duplicating any items that the Inbox Recovery tool has already recovered.

1. Copy the corrupted PST file backup to your desktop. 

2. Change the .BAK extension at the end of the file name to .PST.

Note: If you can’t see the file extension, open the File menu in a File Explorer window and select Change folder and search options. Then, switch to the View tab and uncheck the box next to Hide extensions for known file types.

4. Select Import from another program or file and select Next.

5. Select Outlook Data File (.pst) and select Next.

6. Select Browse and select the backup copy of the corrupted PST file (the one that you just renamed). 

7. Select Do not import duplicates and select Next.

8. Check the box next to Include subfolders. Then, select Import folders into the same folder and pick the account or data file that you want to import the items into.

9. Select Finish.

Once Outlook finishes importing any items, you must manually confirm if the previously missing items are now present. If not, try running the Inbox Repair tool another time.

Third-Party Outlook PST Repair and Recovery Tools

A cursory search online will reveal lots of paid third-party tools that claim to repair damaged or corrupted Outlook PST files. In almost all cases, though, the Inbox Repair tool should be more than good enough for the job. 

Only use a third-party recovery program if Inbox Repair fails to retrieve your data, and do your due diligence by checking online reviews thoroughly before spending any money on them.
