  1. How to reactivate my windows key on my formatted pc?


    I built my pc in 2024 and bought a windows oem key and activated windows in it. Recently I formatted the same computer and installed the windows from 0 by using a windows installment on a flash drive Which is recently prepared. Durin the installation I entered my key, installation processes continued without any warning or any other problem. After the installation completed when I tried to switch to the dark theme on settings, I discovered my windows is not being activated. It was saying " We can't activate Windows on this device because the production key was already used on another device.

    Hi

    Thanks for your reply.

    Reactivating Windows 11 after retrieving the motherboard key involves using the original product key or digital license associated with your system.

    Here are the steps to reactivate Windows 11:

    1. Open Settings:
      • Click on the Start button and select the gear icon to open "Settings."
    2. Navigate to Update & Security:
      • In the Settings menu, click on "Update & Security."
    3. Go to Activation:
      • In the left sidebar, select "Activation."
    4. Enter Product Key:
      • If you have a product key, click on "Change product key" and enter the key when prompted.
    5. Use Digital License:
      • If your Windows 11 was linked to your Microsoft account, you might see an option to troubleshoot and link your digital license. Click on this option and follow the prompts.
    6. Restart Your Computer:
      • After entering the product key or linking your digital license, restart your computer.
    7. Verification:
      • Go back to the Activation section in Settings to verify that Windows 11 is now activated.

    How To Format A Write Protected Flash Memory ?

    ¿You already tried this one?...

    Run CMD


    1. diskpart
    2. list disk

    Then in the 3º step, put the correct number of disk in the list for the usb flash (if it's listed in disk 3, then you'll have to write select disk 3).

    2. select disk #
    3. clean
    4. create partition primary
    5. select partition 1
    6. active
    7. format fs=fat32
    8. assign
    9. exit

    with that commands you will format the flash drive in fat32, if you have a large drive you can select also "format fs=ntfs" in step 7.

    good luck!
