Dell Laptop Bill

If you're referring to the Windows product code, no - that will not be on the invoice.

Only the system service tag will be there.

Hi

IF you mean the embedded 'LICENCE KEY' for the operating system, then I suggest Belarc Adviser to list those details.

Of course you can extract it yourself....

1. Command Prompt Method

1. Open Command Prompt as administrator.

2. Enter the following command:

• text

  wmic path softwareLicensingService get OA3xOriginalProductKey

• Your 25-character product key will be displayed if it is stored in your system firmware.

2. PowerShell Method

1. Open PowerShell as administrator.

2. Enter this command:

• text

  (Get-WmiObject -query 'select * from SoftwareLicensingService').OA3xOriginalProductKey

• The product key will appear in the window.

3. Registry Method

1. Press Windows + R, type regedit, and press Enter.

2. Navigate to:

• text

  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform

• Look for the value named BackupProductKeyDefault - this may contain your product key.

4. Third-Party Tools

• Use free utilities like Magical Jelly Bean KeyFinder, Belarc Advisor, NirSoft ProduKey, or LicenseCrawler to scan your system and display the license key.

Note:

• If your device uses a digital license (common with Windows 10/11 upgrades or OEM devices), the key may not be retrievable, as activation is tied to your hardware and Microsoft account rather than a visible key.

• For systems purchased through volume licensing or organizations, keys may not be individually accessible.

These methods work for most retail and OEM installations.

Always keep your product key secure for future activations or system reinstalls.

NB:  Having/Knowing the 48 digit BitLocker is important, even VITAL, and it may be stored in your MS account, if you have one.
