Windows Security Center Stops Working - Windows 11

I have run into a problem repeatedly recently. On a client computer running Windows 11, if I go to open the Windows Security Center, it won't open and I will get the following message/error:

Some websites will recommend the following:

"Go to the Settings. Select App > Apps & features and type in ‘security’ in search menu box. An icon for Windows Security will pop open. From there, click on the options (three dots) and select Advanced options. Now scroll down to Reset section and click on Reset.

You’ll get a confirmation asking if you really want to reset the app, along with your whole app data. Click on Reset to go with it."

However, so far what I have found is that "Windows Security" is not in the application list at all! 

So how can I reset the app?

Well, what I have found was a simple command you can run from the Windows PowerShell (with administrative privileges) that ultimately solved the problem for me, as well as for some of my clients who have run into this same issue as well.

  • Using Windows' search, just type in "PowerShell"



  • Right-click on its icon, and select "Run as Administrator"
  • Next, copy and paste (or type in) the following script:

Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage

  • Hit Enter, and you should get a screen like this:


That should do the trick!
Your Windows Security Center should now be working again!

Ransomware Infection? This could help!!


Ransomware infections are a very real and very serious problem that general computer users, and businesses alike, should be prepared for!

  • First off, the best prevention to start with is to have good security software installed that can protect you from Ransomware infections (such as Malwarebytes Anti-malware, Kaspersky Antivirus, etc).
  • Secondly, have a good data backup system in place that follows the 3-2-1 backup rule to keep your data safe! 
    • The 3-2-1 backup rule simply states that you should have:
      • 3 copies of your data (your main data and 2 backup copies)
      • On two different media types (NAS drive and a thumb drive)
      • With one copy off-site for disaster recovery (cloud backup, etc).

If you do get hit with a ransomware infection, the website below can help you identify which ransomware you were infected with and if there is a de-encryption tool available to help get your data/files back: https://id-ransomware.malwarehunterteam.com/
