If you enable "Navigation Pane" in Windows 7 Explorer, it shows following 5 items in the pane:
- Favorites
- Libraries
- Homegroup
- Computer
- Network
This tutorial will help you in removing "Computer" item from the Navigation pane as shown in following screenshot:

Simply follow these simple steps:
1. Type regedit in RUN or startmenu search box and press Enter. It'll open Registry Editor.
2. Now go to following key:
HKEY_CLASSES_ROOT\CLSID\{20D04FE0-3AEA-1069-A2D8-08002B30309D}\ShellFolder
3. Now you'll need to create a new DWORD value "Attributes" in right-side section. But Windows will not allow you to create it as you won't have proper permissions.
To get permissions, first right-click on "ShellFolder" key and select "Permissions".

It'll open a new window. Select "Administrators" in user list and check "Allow" box given for "Full Control" permission.

Click on OK button to apply the changes.
4. Now create a new DWORD value "Attributes" in right-side section and set its value to b094010c
5. That's it. Log off or restart your system and "Computer" will no longer present in Explorer window.
NOTE: If you want to restore "Computer" in Navigation pane, simply delete "Attributes" DWORD created in step 4.

It is a handy shortcut. Why somebody wants to remove this?

Because it clutters up the window. I have my own shortcuts to the places I want to go. I have no need or desire to brows through all my folders in the side bar of windows explorer. Microsoft should really give you the ptions to easily enable or disable all these shortcuts so we don't have to use registry hacks to get rid of them.

This is absolutely ridiculous -- this is the total elimination of any semblance of Hierarchy at all~!
And I'm being forced to adopt this critical failure for my aging customers who had trouble accepting the stupidity of My Desktop being higher order than Computer, and My Documents being equal in the same hierarchy..
WHY would anyone (besides a stupid Macintosh user) want to divest themselves so totally of architecture, and HOW can they live with themselves referring to this as a Navigation pane? The term Navigate implies a path -- which this hideous OS has eliminated almost completely~

Unfortunately this tweak also removes computer from the desktop and the browse path when installing new software which can be a pain if you don't usually install to the default location

Seeing Microsoft's conception of what a user SHOULD want in a directory/file management program is a perpetual annoyance--especially because it means I have to scroll down half a page before I can get to my data drive and access the four folders (documents, photos, music, downloads) I use most of the time. You have helped a great deal with the tips for eliminating at least some of the garbage entries (e.g., libraries). I want to thank you.
WISHLIST: a tweak for permanently disabling "My" folders, which stick with you like garlic breath.
All I want to see when I open Windows Explorer is my drives in the left panel and a cascade of subdirectories in the right panel when I click on a drive letter (name desirable but largely optional) in the left panel.
