I have been using this hp laptop for the last one and half years but I have not had the need to servicing it nor do I have any updates. If you keep general precautions, than this laptop can used for long period if time. It’s window defender is very good. If you have Not installed any other anti-Virus in your system its window defender keeps your data safe front viruses. But you have to udate it from time to time. Its battery backup approximately 6 to 7 hours. If you going to buy cheap and long lasting laptop. This laptop might be a good option for you.
