1. Enable Num Lock on the Windows 8 Logon Screen

Some user believes that there is a setting in Computer BIOS that num lock will not be enabled automatically on the logon screen. But let's think that you have enabled the user authentication while logon and your password will be in numerical. So, if you want to enter in the Operating System speedily you have to turn first Num Lock On then type, if in case you forget to turn on then password will be wrong. Here is the simple tweak to Enable Num Lock on the Windows 8 Logon Screen.

• Open "run" (Win Key + R), type "regedit" (without quote) and hit enter.
• After that one window will appear, as shown in below image.
• Now Browse to this location: HKEY_USERS\.DEFAULT\Control Panel\Keyboard

• Done successfully.

In Windows 8 and Windows 7, when File Explorer is launched via the Task bar shortcut, Libraries are shown by default, which is not useful to us. But If I show the tweak that when you click on File Explorer via the Taskbar then My Computer opens with a drive list. Here is simple tweak to follow.

• Right Click on the File Explorer which is on the Taskbar.

• Then Select Properties, it will open File Explorer Properties.

  %SystemRoot%\explorer.exe ,::{20D04FE0-3AEA-1069-A2D8-08002B30309D}
• And click OK, you have done successfully.

3. Customise Default Programs for the Windows 8 Desktop

In Windows, when you click on any image on the desktop then it will not open in Image Viewer or otherwise if you play a video from a desktop then a full screen player emerges out. To avoid all this things we know that we have to set default programs for that. So, here is the simple tweak:

a) Image Viewers

• Click on the Windows Key from your Keyboard, type Default Programs and hit Enter.
  

  
•  Select set your default programs.
  
•  Select Windows Photo Viewer and then click set this program as default.

4. Windows 8 Multi-Monitor Tweaks

While designing Windows 8, Microsoft keep the concept of multiple monitors support in mind. If you use multiple monitors then you can do different works on both of them and also works can be finished fast. For that you have to customize and also we have to put different wallpapers on specific monitors. This article is a compilation of multi-monitor tips that will help any Windows 8 power user. 

a) Taskbar Customization

Now, right click on Taskbar and select properties. You will see a pop-up properties window and on the bottom half of the Taskbar tab you will see the new Multiple Display options, as shown in below image:

There you will see the three options:

1. All Taskbars
2. Main taskbar and taskbar where window is open
3. Taskbar where window is open

So, select as per your requirement and many others options are also there to customize.

b) Background Customization

This is very simple tweak, you have to right click on the specific image and on which monitor you want to display select that. And also select position settings.
