Symptom:
 
You are a novice user with the Windows registry and are attempting to perform a Manual Clean Uninstall of the scanner and software provided.
 
Solution:
 
This document gives a brief description of and instructions on how to navigate through the Windows Registry. Before you begin editing the registry you may want to export a back-up. Please click VIS1034 - Import or Export Windows System Registry for instructions on how to complete this process. You may want to print these directions to refer back to them during your manual uninstall process.

Hint: When browsing through the registry you can press the first letter keyboard key of the key name you are looking for to jump to that alphabet key list.
 
Note: For Windows 2000, XP and Vista you need to be logged in as a user with administrative privledges. If you work for a company with an IT department you should contact your support department to verify you have sufficient privledges to proceed. If you purchased or built your own computer you should already have administrative access.
 
Access the Windows Registry:
  • Windows 98 / Me / XP:
    1. Go to "Start" and select "Run".
    2. Type in "Regedit" then click on "OK".
  • Windows Vista:
    1. Go to "Start" and click in the "Start Search" box.
    2. Type in "Regedit" and press the Enter key on your keyboard.
  • Windows 2000:
    1. Go to "Start" and select "Run."
    2. Type in "regedt32" then click on "OK".
 
Registry Folders:
After opening the registry you will be looking at a window with a list of yellow folders down the left side, this is called a "folder tree". Each folder, which in the registry is called a "Key", will have a "+" sign next to the key indicating that there is a sub key within the current key. If you click on the + next to this parent key, then the sub keys, also known as child keys, are displayed. In most cases, if there is a + next to a folder, it is considered both a parent and a child key. It is a child key to the parent key that revealed it, and it is a parent key of the child keys it contains. A true "child" key will have no symbol, neither "+" nor "-", next to the folder key.

Windows Vista Users: The Vista registry no longer uses the "+" and "-" symbols. You will see an unfilled arrow pointing to the right next to each key. When you click on the triangle it will automatically fill in and point the arrow down. This indicates that the current folder is open.

The contents of each key will be listed on the right side of the screen, the data you see on the right are called the key "values".
  • Windows XP and Vista have 5 parent keys. When opening the registry these keys will show as a list on the left side of the registry window:
    - HKEY_CLASSES_ROOT
    - HKEY_CURRENT_USERS
    - HKEY_LOCAL_MACHINE
    - HKEY_USERS
    - HKEY_CURRENT_CONFIG


  • Windows 2000 also has the same 5 parent keys, however, when opening the registry in 2000, the 5 keys will be in separate tiled windows labeled as follows:
    - HKEY_CLASSES_ROOT on Local Machine
    - HKEY_CURRENT_USERS on Local Machine
    - HKEY_LOCAL_MACHINE on Local Machine
    - HKEY_USERS on Local Machine
    - HKEY_CURRENT_CONFIG on Local Machine


  • Windows 98 and Me have 6 parent keys and like XP they show as a list on the left side of the registry window:
    - HKEY_CLASSES_ROOT
    - HKEY_CURRENT_USERS
    - HKEY_LOCAL_MACHINE
    - HKEY_USERS
    - HKEY_CURRENT_CONFIG
    - HKEY_DYN_DATA
 
Navigating the Registry:
You can open and close, A.K.A "expand" and "collapse", keys by clicking on either the "+" sign to expand the key or the "-" sign to collapse the key.

When the instructions tell you to "browse to the following registry location" this means that you are to click on the "+" next to each folder in the path listed until you get to the last folder in the location given.

In the example picture below we have navigated the registry to the following location:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

This registry location tells Windows which applications to load when Windows launches, these applications are what you see in the lower-right side of your screen next to the system clock. In the example picture below, please note that on the right side of the screen the key value for the ScanSoft PaperPort WebCapture feature is set to start as soon as Windows boots up.
 
This example shows the Windows XP registry. Reminder: this is similar to how the Vista, 98 and Me registry screens look like.
 
Here is an example of the Windows 2000 registry:
 
Setting Permissions:
As stated above, in Windows 2000, XP and Vista you must be logged in as a user with administrative access. However, some registry keys are still locked from being deleted. You must manually set the permissions on these keys before you can delete them.

  • Windows XP and Windows Vista users - if you get a message stating you do not have permissions to delete a registry key, please do the following to grant permissions:
    1. Right-click on the key and choose "Permissions..."
    2. In the Permissions window locate and select your user name in the top half of the window.
    3. In the Permissions window click on the box under the column "Allow" and next to the term "Full Control">
    4. Click on "OK" to apply the changes and close the Permissions window.
    5. You should now be able to delete the registry key you just set permissions for.

  • Windows 2000 users - if you get a message stating you do not have permissions to delete a registry key, please do the following to grant permissions:
    1. Click on the key to select it.
    2. At the top of the registry window, on the File menu bar, locate and click on "Security".
    3. Click on "Permissions..."
    4. In the Permissions window locate and select your user name in the top half of the window.
    5. In the Permissions window click on the box under the column "Allow" and next to the term "Full Control">
    6. Click on "OK" to apply the changes and close the Permissions window.
    7. You should now be able to delete the registry key you just set permissions for.
