If you need to reinstall your system, activate Windows, or simply keep a backup of your license, knowing how to retrieve your Windows 11 Home product key is essential. Fortunately, there’s a simple way to do it using PowerShell.
​

Why Your Product Key Matters
Your Windows product key is a unique code that verifies your operating system is genuine. You might need it when:

• Reinstalling Windows
• Transferring your license to another device
• Troubleshooting activation issues
  
  

Method: Using PowerShell
Follow these steps to quickly retrieve your product key:

1. Open PowerShell
   • Press the Start button
   • Type PowerShell
   • Right-click on Windows PowerShell and select Run as administrator
     
     
2. Enter the Command
   Copy and paste the following command into the PowerShell window:
   (Get-WmiObject -query 'select * from SoftwareLicensingService').OA3xOriginalProductKey
   
   
3. View Your Product Key
   • Press Enter
   • If your system has an embedded key, it will appear instantly on the screen

Important Notes

• This method works best for systems that came with Windows pre-installed, where the key is stored in the BIOS or firmware.
• If nothing appears, your system may be using a digital license linked to your Microsoft account instead of a traditional product key.
  
  

Alternative Tip

If your key doesn’t show up, your Windows activation is likely tied to your hardware or Microsoft account. You can check activation status by going to:
Settings → System → Activation


Final Thoughts

This is one of the fastest and most reliable ways to retrieve a Windows 11 Home product key without using third-party tools. It’s always a good idea to store your key securely once you find it, just in case you need it later.

Πρώτη φορά που μου χρησίμευσε το κουτί σκληρού δίσκου που είχα κερδίσει από το cpusers.gr. 

Μέχρι τώρα δεν το είχα χρειαστεί γιατί δεν χρησιμοποιούσα τότε (πριν το 2010) sata σκληρούς δίσκους. Τώρα που τα έπαιξε το laptop μου, το άνοιξα, αφαίρεσα τον δίσκο και τον σύνδεσα στο κουτί όπως βλέπετε παρακάτω στις εικόνες.

Και δούλεψε... έτσι έσωσα και όλα τα αρχειάκια μου... Μετά σύνδεσα πάλι τον δίσκο στο laptop και το άφησα εκεί για να υπάρχει ίσως για μελλοντική χρήση.
