I would opine that there is no real functional need for 90% of Windows users to upgrade from XP, unless they do gaming, most of which is a poor use of time, but with support running out (no more security updates) then it would leave it more vulnerable, but again, pray and press and seek to be good and wise.
As for hitting alt and F4 since you installed Windows 8, yes, and for me it just closes whatever window is before me. You did them together right? Perhaps it is because you are using a laptop.
Try using Windows key and D so that you are on your desktop, then click on Alt+F4 to bring up the shutdown dialog box. But the Right click extender can add a dialog to do this, while the old slawdog shutdown will run in your system tray and give you the same options. http://www.snapfiles.com/get/smartshutdown.html
Also, to shutdown the metro apps, i read you can click on and and drag the top of the app to the bottom of the screen.
Lol I must have hit alt F4 over twenty times and it would not work for me. I thought they changed it . It’s a combination of having small hands and the laptop .I have to hit the keys with two hands to get it to work on this thing.
Thanks a bunch :)
Clicking and dragging does work to shut the app down but on the laptop it is easier to us the corner
