If the laptop is only used for shopping and various minor "office" tasks, windows 7 is much easier to deal with.
No need to deal with windows 10 randomly causing issues.
Install windows 7, make sure to do all the security updates (no need to go nuts and install ALL available updates, many do not even mess with what you want to do), and then be sure to run the Windows Experience Index if you have an SSD. This will tell windows to do further adjustments with the SSD, such as verifying TRIM is enabled, and prefetch is limited. Windows is supposed to do this during installation if it detects an SSD, but running the WEI thing enforces it.
to find it, find control panel in the start menu and click on performance information and tools
