I had windows 8 on my computer, but I had some problems with the computer, so the computer company downloaded windows 8.1, and I am still having problems.
I had users\harriet\appdata\local\pokki\engine\hostappservice.exe on my computer, but something went wrong and I cannot locate it? What do I need it for? Really appreciate your help. Thank you, Harriet Hughes hcch1947@yahoo.com

Pokki is often bundled with other software download. Allows you to download apps and games. It is not needed for your computer.

@Dawne: It should be possible to uninstall Pokki from the Windows Control Panel. If that does not work, you can remove Pokki with FreeFixer.

Microsoft is intent on making users suffer while spying on them. They allow you to use Windows 8.1 only after getting your email adress and put your name and this info on the screen. Their style is designed to make people getting used to being oppressed. Their media player can have "Deleting files if they are removed from the list" as a default. They love to mimic idiocy with phrases like "Let's look at the internet for a solution" when your problem is "no net connection" etc. They can lose or erase your files. Host App Service is just another example of tyranny.

I am using windows 10. To be honest pokki and their dumb program is shit. My laptop was heating up like crazy because of it. Once I remove it BOOMMM cpu temp goes from 80 to 38 in nothing. I recommend to remove it as fast as possible.
