Activate Windows Watermark

Hi Duncan,

The Windows activation watermark is usually appearing if the activation servers detect that a device is not activated. For further help with activating your copy of Windows 10, visit this
link. If the same issue persists after performing the troubleshooting suggestions on the link, follow these steps:

• Using Cortana, type Notepad and then click on Notepad (Desktop app).
• Type the following commands in Notepad:
  • @Echo off
    
    taskkill /F /IM explorer.exe
    
    explorer.exe
    
    exit
    
    
• 
  Save the file and name it as Activation.bat.
  
• 
  Change the Save as type to All files.
  
• 
  Locate the file, right-click on it and then choose Run as Administrator.
  
• 
  After running the file, restart your computer and then check if the same issue persists.

Windows saying not activated after motherboard upgrade

Hi,

I recently upgraded some PC parts (new motherboard, RAM, processor, video card) and ever since then I have a watermark in the bottom right of my display reading "Activate Windows - Go to Settings to activate Windows."

I took advantage of the free upgrade to Windows 10 back when they were allowing Windows 8 users to upgrade to Windows 10. I don't remember receiving an activation key during this upgrade.

I've read online that installing a new motherboard can occasionally cause issues with OS activation. How can I reactivate my Windows without having to purchase Windows 10.

Some things to note:

• This watermark was not there prior to installing the new motherboard
• As some places (and a Microsoft Tech Support member) suggested, typing the query "wmic path softwarelicensingservice get OA3xOriginalProductKey" into CMD just returns with "OA3xOriginalProductKey". The Microsoft Support member seemed confused by this and said there was nothing further she could do.

Thanks!

 

Activate Windows watermark

I keep getting the Activate Windows watermark. I have done the suggested things such as editing the regedit, creating the removal.bat file, but the watermark keeps returning.

My windows is legit, and I have had it for 3 years now. Can someone please help me?
