Deactivate then activate on cleaned Windows 10 with 3 device 2 year Premium

Recommended Posts

I have a 3 device 2 year Premium license. I went to my account under devices and found 2 devices activated as expected. One for my Windows 10 Pro PC and the other for my Windows 10 Pro laptop.

I need to deactivate my PC one, do a clean Windows 10 install (since a Windows update decided to keep going in circles - likely a corrupted file), then install and re-activate the PC MB.

How do I tell which of the two devices shown in my account is my PC when both devices show windows 10 and have the same activation code? Am I missing something on the page to show me the computer names?

Thanks for posting in the Malwarebytes for Windows Help forum.

If you are having technical issues with our Windows product, please do the following:

Malwarebytes Support Tool - Advanced Options

This feature is designed for the following reasons:

  • For use when you are on the forums and need to provide logs for assistance
  • For use when you don't need or want to create a ticket with Malwarebytes
  • For use when you want to perform local troubleshooting on your own

How to use the Advanced Options:

  1. Download Malwarebytes Support Tool
  2. Double-click mb-support-X.X.X.XXXX.exe to run the program

  3. Place a checkmark next to Accept License Agreement and click Next
  4. Navigate to the Advanced tab
  5. The Advanced menu page contains four categories:
    • Gather Logs: Collects troubleshooting information from the computer. As part of this process, Farbar Recovery Scan Tool (FRST) is run to perform a complete diagnosis. The information is saved to a file on the Desktop named mbst-grab-results.zip and can be added as an email attachment or uploaded to a forum post to assist with troubleshooting the issue at hand.
    • Clean: Performs an automated uninstallation of all Malwarebytes products installed to the computer and prompts to install the latest version of Malwarebytes for Windows afterwards. The Premium license key is backed up and reinstated. All user configurations and other data are removed. This process requires a reboot.
    •  Repair System: Includes various system-related repairs in case a Windows service is not functioning correctly that Malwarebytes for Windows is dependent on. It is not recommended to use any Repair System options unless instructed by a Malwarebytes Support agent.
    • Anonymously help the community by providing usage and threat statistics: Unchecking this option will prevent Malwarebytes Support Tool from sending anonymous telemetry data on usage of the program.
  6. To provide logs for review click the Gather Logs button
  7. Upon completion, click OK
  8. A file named mbst-grab-results.zip will be saved to your Desktop
  9. Please attach the file in your next reply.
  10. To uninstall all Malwarebytes Products, click the Clean button.
  11. Click the Yes button to proceed. 
  12. Save all your work and click OK when you are ready to reboot.
  13. After the reboot, you will have the option to re-install the latest version of Malwarebytes for Windows.
  14. Select Yes to install Malwarebytes.
  15. Malwarebytes for Windows will open once the installation completes successfully.

Thanks. Thing is, my account rightly shows 2 identical Windows 10 devices with identical license numbers. Is the one on the top of the page the PC or the laptop? I don't want to deactivate the wrong device.

Have you already wiped and reloaded Windows?

Good. Open Malwarebytes on that computer and deactivate it in the program like I showed in my screenshot and wait for it to go to the free version.

The computer will have to be online though for it to deactivate.

That releases the device in your account and then go on with reloading windows. Be sure to do your reload within 24 hours or the key might auto reactivate but it is not supposed to..

AH! That makes sense. Will do. Cheers Porthos.

Be sure to use the current version of Windows 21h2 when reinstalling.

I would also suggest keeping image backups so you will not have to reload Windows from scratch again. I prefer Macrium Reflect.

I backup monthly before the patch Tuesday update.

I had to restore from repeatedly since the W10 update ending in 186 just stayed red with the circle chasing itself forever.

We have people here that might be able to assist you with fixing the system so you do not have to reinstall.

If you are interested, please tell me and I will get you the help.
