Windows 11 License / Serial Number – How to transfer

Moving Your Windows 11 License to Another Computer

1. Verify Your License Type

  • Retail keys can be transferred.
  • OEM keys are tied to the original hardware—not transferable.
  • Digital entitlement licenses link to your Microsoft account and may auto-reactivate on new hardware.

2. Extract Your Product Key

Open an Administrator Command Prompt and run:

wmic path softwarelicensingservice get OA3xOriginalProductKey

If that returns blank, try in PowerShell (Admin):

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

If still blank, you likely have a digital-only license—no key is needed; just sign in on the new PC with your Microsoft account.

3. De-register on the Old PC

In an elevated Command Prompt, run:

slmgr.vbs /upk

This uninstalls the key from the old machine, freeing up the license.

4. Install & Activate on the New PC

Option A: Command Line
Open Admin Command Prompt and run:

slmgr.vbs /ipk YOUR-25-CHAR-KEY-HERE
slmgr.vbs /ato

Option B: Settings UI
Go to Settings > System > Activation > Change product key, paste your key, and follow the prompts.

If activation fails, confirm you have a Retail license (Settings > System > Activation) or contact Microsoft support for a manual transfer.

Touch ID Stopped working on MacBook

You need to reset your secure token.

sysadminctl -secureTokenStatus mlr
sysadminctl -secureTokenOff mlr -password - -adminUser Manamana -adminPassword -
sysadminctl -secureTokenStatus mlr
sysadminctl -secureTokenOn mlr -password - -adminUser Manamana -adminPassword -
sysadminctl -secureTokenStatus mlr

On a Mac, a Secure Token is a crucial account attribute that enables users to perform specific, system-level operations, particularly those related to FileVault encryption and system security. It's essentially a permission that allows a user to manage and decrypt encrypted data on the Mac.
Here's a more detailed explanation:

Purpose:

Secure Tokens are used to authorize users to manage FileVault, which is Apple's built-in encryption feature. This includes enabling and disabling encryption, as well as decrypting the system drive.

Works okay, attachments are messed up.

Use this viewer instead and attachments might work.

To install msgconvert, open a shell, then type:

sudo apt-get install libemail-outlook-message-perl

Then cd to the folder where you have the .msg file or files, then type:

msgconvert *.msg
