I am new to this forum and will appreciate your help and any information from all.
My question: Having bought a PC About a year ago with software installed. No product key or sticker given by supplier.
Lately, I keep getting the following on start-up "Windows licence expires shortly. Activate before 3 December 2015" "Enter the product key"
It also shows the last four figures of a product key which thus not correspond to the activation keys, that I have in my PC Information.
Also, although it says activate now by entering key, it won't accept any figures.
Any help please and how can I sort this out permanently.
My windows is 8.1
Thanks in advance
