Window 11, it's an ACER laptop, the last one i had lasted well over 2 years and that was a crap one!! The last one was an HP cheap thing, it bearly lasted a year, the new one is quite expensive and has some great reviews if there true but i'm happy with it, 15.6" screen and 1080 HD.Laptop, is it a chromebook, windows or a mac? apparently they all need a waterproof keyboard cover for some users![]()
