Win10 won't activate after RAM change

Hey! I replaced my old RAM cards with two new ones, and now I'm stuck with a "activate windows" prompt in the bottom right corner of my screen. The troubleshooter does not seem to do anything (tried checking the changed hardware option + chose my device
in the list of devices + it said win10 was now activated.... but the prompt won't leave.)

I got win10 during the free upgrade period, and thus I don't have a product key... Any suggestions?

 

Activation problems after hardware changes and reinstallations.

Hi Meli,

Thank you for posting the query on Microsoft Community.

I do appreciate your efforts and time.

Was Windows 10 activated before re-installing it?

Along with the suggestions provided by Greg, you can also refer the steps below.



The only hardware changes that can negatively impact activation status once you upgrade to free version are the changes to the:

• CPU
• TPM
• Motherboard replacement

The following changes are examples of hardware changes that will NOT impact the activation status:

• HDD/SSD
• Video card
• Adding extra memory

If you replace the CPU, TPM, or Motherboard you may have to re-activate but this will not require a purchase of Windows 10.
