You can load Ubuntu to work side by side with Windows if you wish in case you don't like it and it's free. It replaces Windows as your operating system.It's windows 7 and they said to just buy another.
It's at least 10 years old and I've had to start restarting it sometimes cause it will freeze up.
My android phone is just as bad but it's like 20 years old. Battery is swole up and gonna explode one of these days.
Trying to hope it lasts til october then I'll get a new one.
There is also Linux Mint that is supposed to be even better.
