Hello Acer Community,

I have an Acer Predator PH315-54 that originally came with Windows 10 Home 64-bit pre-installed and activated (OEM license).

Recently, I gave my laptop to a friend, and now it shows Windows 10 Pro, and Windows is no longer activated. I’m getting activation errors like 0xC004C003. I believe the edition was changed by entering a random product key, possibly from an unofficial source.

Now, I want to:

  1. Recover the original OEM product key that came with the laptop,
  2. Revert to Windows 10 Home, and
  3. Reactivate it using the genuine key.

I tried running this command in Command Prompt:
wmic path softwarelicensingservice get OA3xOriginalProductKey

I entered the product key but it couldn't proceed.


But I’m not sure if the result is valid or if this is the correct method. Can Acer support help me retrieve the official OEM product key linked to my device?

I have the device’s serial number and proof of purchase if needed.

Thanks in advance!
