I have a 10 month old £ 1000 HP laptop, windows 10 was installed, it was sent to Knowhow with a minor problem. It was returned with Window 8 !!!!. When I questioned this , I was told my HP Envy only had windows 8 installed. I purchased my HP with windows 10, I have used windows10 for 10 Months so WHY ? are the people in " Don't know how" insisting I have Windows 8. I took this out on a 3 year lease because It would me repaired immediately AND I would receive laptop on loan???? When it came to the repair I was told it could take up to 14 days!!!!????? AND no laptop loan. DO not lease, Do not buy, Currys DO not Knowhow , I was informed that I only had a 30 day warranty. I am sure Trading Standards would contradict this statement
