Windows 10: How do I fix my problem activating windows 11 after a reset?

I just reinstalled windows 11 and it wont let me activate it after getting error code 0xc004c003. I tried to troubleshoot it but it said "it looks like the hardware on this device has changed. Make sure your connected to the internet and try again later." I am connected to the internet and signed into my microsoft account that had my original install of windows 11 WITH the product key. I don't know how to fix this please help.

Windows 11 Activation after a reset

Hello MandlaSA

Welcome to the Microsoft Community.

It sounds like your Windows 11 installation needs to be reactivated and the taskbar issue is also impacting your user experience. Here's a step-by-step guide to help you troubleshoot and resolve these issues:

Windows Activation Issue

1. Digital License: If your Windows 11 was activated previously and linked to your Microsoft account, it should automatically reactivate. Ensure you're connected to the internet.
   
2. Product Key: If you have a product key, you can try re-entering it.
   
   1. Right-click the Start button and select "System."
      
   2. Click "Activation" on the left pane.
      
   3. Click "Change product key" and enter your Windows 11 product key.
      
3. Troubleshooter: Use the Activation Troubleshooter.
   
   1. Go to Settings > Update & Security > Activation.
      
   2. Click "Troubleshoot" to run the activation troubleshooter. This can help resolve common activation issues.
      
4. Microsoft Account: Ensure you're logged in with the Microsoft account linked to your digital license.
   
   Go to Settings > Accounts > Your info to check which account you're logged in with.
   

Taskbar Issue

For the taskbar not showing, you can try the following fixes:

1. Restart Windows Explorer:
   
   1. Press Ctrl + Shift + Esc to open Task Manager.
      
   2. Find "Windows Explorer" in the list, right-click it, and select "Restart."
      
2. Use Command Prompt:
   
   1. Press Ctrl + Alt + Del, then select "Task Manager."
      
   2. Click "File" > "Run new task."
      
   3. Type cmd and check the box to create this task with administrative privileges.
      
   4. In the Command Prompt, type the following commands, pressing Enter after each:
      
      
   5. Wait for the commands to complete and then restart your computer.
      
3. Check for Updates: Sometimes, Microsoft releases fixes for such bugs through Windows Updates.
   
   1. Press Windows Key + I to open Settings.
      
   2. Go to "Update & Security" and click "Check for updates."
      
4. Create a New User Account: If none of the above works, creating a new user account can help.
   
   1. Open Settings > Accounts > Family & other users.
      
   2. Click "Add someone else to this PC" and follow the prompts to create a new account.
      

If there is anything not clear or I can't understand your problem, please do not hesitate to let me know.
