Thanks again usnorway. The laptop did come with windows 8 installed at purchase. I was thinking perhaps I should allow Windows 8.1 to install and see how it goes. The laptop is Packard Bell EasyNote TE. Does anyone know of any reason why 8.1 should not work on this laptop.
Thanks USNorway. I have tried all 3 methods in the link you attached and unfortunately none of them worked. I think you are right in saying that I have a partial 8.1 upgrade. Is there any way I can reverse that and go back to 8.0 ?
I did update to 8.1 and I found the laptop was so slow that it was unusable. So I reverted to 8.0 and it has been OK since then - apart from these messages that keep popping up.
I have Windows 8.0 and I do not want to upgrade to 8.1, but I keep getting this message coming up (sorry its upside down !). Can amyone help me get rid of this message please.
