After a certain Windows 8.1 update, icons and text disappear from Outlook and Lync 2013 tiles. All you can see are two blank blue tiles. Let me show you how to bring back icons and text.
If you put your computer into hibernation, the next time you turn it on, you'll get all your windows and programs open just the way they were before the shutdown.
If you leave your computer running on a 24/7 basis you might be interested in determining the amount of uptime that has accumulated since the last reboot.
You have more people using one computer and you don't want them to be able to shut it down using a shutdown button on Windows logon screen, this is how you remove it.
