A:AnswerBecause it's running Windows 10, you'll be able to use any version from Office 2007 on. Older versions may still work if you run them in compatibility mode. Microsoft support for Office 2010 will end in mid 2020.
A:AnswerTyping delay can be caused by any number of things. The most common are memory problems, outdated keyboard drivers, and viruses called "key loggers". Key loggers are viruses that track your keystrokes, allowing a third party to steal passwords and other information. Sometimes programs are doing things in the background which "detracts" from the app you are typing in. You should run a virus scan, and hit CTRL-ALT-DEL and see what is taking up a lot of memory in your pc. If you are unable to improve the situation contact HP support at https://support.hp.com.
