Windows Activation popup (code 0x8004fe21) even when my Windows is activated

[Gildawie]

A "Windows Activation Technologies" window continually pops up to say my copy of Windows 7 may not be genuine (code 0x8004fe21) and needs to be validated.
This started recently, after about a year of use. The system reports Windows is genuine and activated.
Computer is HP Z240 and was purchased from a major dealer. No major changes have been made to the hardware.



I am unable to validate Windows through the popup even using Internet Explorer with security as low as possible. Messages indicate that script(s) are not running properly.
MGADiag.exe tells me Windows is valid and activated, but the popups still appear.
Does anyone know how to fix this annoying problem?

Thanks

Do this - Disable Auto Activation feature in Windows 10/8/7

HappyAndyK,

I have read your possible solution.
My wifes aging acer laptop with W7 Home Premium OEM is popping up the message above about not being genuine since the last three months.

I would like to try your solution, and I am confident that it will work, but does the not genuine notice also imply blocking some of Windows updates? So, if I disable the Auto Activation feature to get rid of the pop-up it probably does not change the partial blocking of windows update.

Please, correct me if I make the wrong conclusion.

Thanks in advance
