Turn Live Tiles on and off - Windows 8

Use the Live tile option to customize what you want to see.
When looking at the plethora of tiles on your Start screen, the view can get stagnant, despite all the pretty colors.This is where Live Tiles come in. They offer real-time data right on your Start screen, and you don't need to open any apps. For example, the Weather tile will show you the current conditions, and Mail will show you the subject of the latest message you've received.
You can customize which apps are live and which aren't by right-clicking on the tiles. A settings bar on the bottom will pop up with an option to turn the Live Tile on or off. Simply select the preferred option, and you're all set. Note, however, that not all apps have a live, real-time data-streaming option.

Start in Safe Mode - Windows 8

Safe Mode is a great way to get into your system when something won't allow you to start up normally. Troubleshooting becomes a breeze when corrupted drivers and files aren't loaded that prevents a system from functioning. It used to be as easy as pressing F8 when the system starts up, but doing so with Windows 8 will take you to Automatic Repair Mode. The trick to getting back to good old fashioned Safe Mode? Hold down the Shift key and press F8 while booting up.
This takes you to the Recovery mode. Select "advanced options," then "troubleshoot," then the "advanced options" again (there are a lot of advanced options). Select Windows Startup Settings and finally the Restart button. This will reboot the computer and give you the option to boot into Safe Mode.
If you need to get into Safe Mode from within Windows, open the dialog box (the Windows key + R) and type "msconfig" (no quote marks). Select the Boot tab and check the Safe boot box. The system will continually boot into Safe Mode until you go back and uncheck the box.

Refresh your PC - Windows 8

Enjoy a fresh PC without losing everything.
If your system is feeling a little sluggish, it may be time for a refresh. In the past we would have to find our copy of Windows 7, back up all of our data, and perform a fresh install to enjoy that back-to-factory-fresh feeling. But now Windows 8 allows you to perform a fresh install from within Windows without losing any data.
In order to perform the refresh, go to Settings and click the Change PC Settings tab near the bottom. Select the General tab and find the "Refresh your PC without affecting your files" section near the middle (you may also select "Remove everything and reinstall Windows" to get the true factory settings treatment). Select "Get started" and press "Refresh." After a few minutes the PC will restart, and you will have a fresh copy of Windows 8.

Log in without a username or password - Windows 8

To speed up the log-in process, you may want to disable the username and password log-in screen. You can do so by opening the Run window (press the Windows key + R) and typing in "netplwiz" to access the User Accounts dialog box. Uncheck the box near the top that says "Users must enter a user name and password to use this computer." ClickOK, and enter the username and password one last time to confirm your choice, and you are all set for easy access to your system.

Boot to the desktop without an app - Windows 8

Skip the Start screen and get right to the Desktop.
One of biggest complaints about Windows 8 is that it boots straight to the Start screen—an annoyance for many committed desktop users. The Start8 utility helps you avoid this indignity (among other cool features), but you can actually boot straight to the desktop without installing anything extra.
Go to the start screen and type in "schedule" to search for Schedule Task in Settings. Click on Task Scheduler Library to the left, and select Create Task. Name your task something like "Boot to desktop." Now select the Triggers tab, choose New, and use the drop-down box to select starting the task "At log on." Click OK and go to the Actions tab, choose New,and enter "explorer" for the Program/Script value.
Press OK, save the task, and restart to test it out!

Create a picture password - Windows 8

A fun way to protect your system.
Using a picture password is a fun way keep your device secure while not having to remember a complex password. To enable it, press the Windows key + I to get to the settings charm. Click "Change PC settings" at the bottom right, and go to the Users tab. Under "Sign-in options" will be the "Create a picture password" button. This will give you the option to choose any picture, and then define three gestures anywhere on the image. Your gestures can be circles, swipes and clicks.
For example, to set a picture password for the image above, you could click on the highest palm tree, draw a circle around the island, and then swipe down from the lens flare in the upper right. Just beware: The direction of each gesture matters! After confirming it a couple times, your picture password will be set.

Share and share alike - Windows 8

Play with the Share charm in every app.
Windows 8 is Microsoft’s first social-media-aware PC operating system. Using the Share button located on the Charms bar, you can pick any number of elements from your Windows 8 Store apps—say, a location from your Maps app, a news story from the Finance app, or a even a contact from your People app—and then distribute that item to friends via other Windows 8 programs.
Perhaps most conveniently, you can quickly share a photo via email or Twitter, or to your own SkyDrive or Windows Phone. The Share button is contextual, and the more you use it, the more you’ll discover which apps share with each other, and which don’t. (Hint: None of your desktop apps offer sharing opportunities through the Charms menu.)
