Create a new string value named "Shell Icon BPP" in the key below. Change the value to equal the color depth supported by your video card (e.g. '16' for 16-bit graphics cards or '24' for 24-bit graphics cards)

Note:
You need a graphics card capable of displaying above 256 colors for this to be useful.

Registry Settings:
Key: [HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics]
Value Name: Shell Icon BPP
Data Type: REG_SZ
Data: 16

The first step is find the system ID of the folder you want to add, these ID's can be found under the [HKEY_CLASSES_ROOT\CLSID] key. The Control Panel's key is called [HKEY_CLASSES_ROOT\CLSID\{21EC2020-3AEA-1069-A2DD-08002B30309D}] and the ID is the last set of number after CLSID, in this case '{21EC2020-3AEA-1069-A2DD-08002B30309D}'.

Once you've found the ID the hard work is done, now all you need to do is right-click on the Start button and chose open.

1. Go to the key "HKEY_CLASSES_ROOT\*\shell", if it doesn't exist create it.
2. Under shell create a new key called open, and edit the string "(Default)" to read "Open With Notepad".
3. Under open create a new key called command, and edit the string "(Default)" to read "notepad.exe %1".

Now when you right click on a file you should see "Open with Notepad" as one of the options

Registry Settings:
Key: [HKEY_CLASSES_ROOT\*\shell]

Open your registry and find the key below.

Create two new string values of 'Wallpaperoriginx' and 'Wallpaperoriginy'. If the values already exist then you simply modify them.

Set the value of 'Wallpaperoriginx' to equal the horizontal offset (i.e. 300), and set the value of 'Wallpaperoriginy' to equal the vertical offset (i.e. 200.) Then either restart Windows, or change your background image through the Control Panel.

Note:
The image is offset from the center of your desktop, so you can use positive and negative values.
