Laptop window 11 (Charlton SE7)

Hi we are trying to get a laptop running windows 11 for my teen gcse. We was gifted one but sadly it’s got a fault and curry’s recycled it yesterday. We are a disabled household so this would be a huge help as it last five months of GCSES and we part home school with our EHCP plan. I’ve reached out to many charities to no avail.
