I have already preinstall on my window 8. I was reading the reviews on the window 8and the sype app and I read that you couldn't sign out off skype on the window 8 charm app. So I am wondering, can I download skype from the official website to my desktop? To me I want to sign out off my skype account after I am done because I want skype account to be save.

Where did you hear you can't sign out? Press Alt+F4 and it will close the app.

But if press Alt+F4 will it sign me out or will I be still sign into it?

Alt+F4 will shut down the app disconnecting you.

But will it remember my user name and password?

If you choose to allow it to remember it, it will.

But if I am sign into my Microsoft user name for my hp laptop, will that still work?

Will that still work for what? If you are signed in using your Microsoft account, then, when you load Skype it should automatically log you in. But, if you close down Skype with Alt+F4, it is removed from memory.

When I push Alt+F4, will it automatically not log me in?
