Windows 8
I have Windows 8 on my desktop and Windows 8.1 on the laptop. When I first received them I bought the Windows 8 for Dummies and Windows 8 for Seniors. I never touched the computers for several days and then told myself if others can learn them so can I (even my hubby can work them now). There are still days I have to search for things but all in all I am happy with them.
