How to Remove Windows 95/98 Registry Entries Automatically

MORE INFORMATION

1. Use any text editor (such as Notepad) to create the sample Del-reg.inf file shown below. Note that Del-reg.inf is not a required name, but it is used in these instructions.

         ; This file called  Del-Reg.INF deletes the registry entries listed
         ; under the [RegChange] section.  In this example it deletes the
         ; UserName value name under the key HKLM\network\Logon
   
         [Version]
         signature="$CHICAGO$"
   
         [DefaultInstall]
         ; DelReg = RegChange
   
         [RunIt]
         DelReg=RegChange
   
         [RegChange]
         HKLM,Network\Logon,username
         HKLM,Network\Logon\keyname,
   						

Notes for this Sample File

• The line below the [DefaultInstall] section is remarked out with a semicolon to prevent someone from accidentally running the .inf file. If you want the option to run the .inf file without using Rundll, you should remove the semicolon.
• RunIt is an arbitrary section name in the .inf file that should be executed.
• The value following RunIt has the following meanings:

  0 - Informs Windows 95 that a reboot is not necessary.
  1 - Always silent reboot
  2 - Always prompt reboot
  

• Below the [RegChange] section is a value called username and a value called keyname to be deleted. These are sample entries and should be modified to list the registry entries that you want to be removed.
• The entry in the [RegChange] section lists the registry entry or entries that you want to remove. Below are some guidelines for the proper syntax:

  root-key, sub-key, [value name]

  The value name is optional and is denoted by the [] brackets. The comma place holder shown above must be included in this line. Please note that if the sub-key or Value name contains spaces you need to use quotes. Registry entries between quotes may be case sensitive. For example:

        HKLM,SOFTWARE\"XYZ  inc"\settings,,
  						

  The root-key is represented by one of the following abbreviations:
  
  

  HKCR is short for HKEY_CLASSES_ROOT
  HKCU is short for HKEY_CURRENT_USER
  HKLM is short for HKEY_LOCAL_MACHINE
  HKU is short for HKEY_USERS

  The sub-key is the continuation of the path to the value to be changed, for example:

  HKLM,SOFTWARE\Microsoft\Windows\currentVersion\Fonts

  removes the Fonts Key and all of its contents.
  
  The value name entry allows the definition of a particular entry to be removed from a sub-key.
• To run this sample file automatically when you log on to your computer, type the following line in the login script:

  RunDLL setupx.dll,InstallHinfSection RunIt 0 path\Del-Reg.inf

  where path is the location of the Del-reg.inf file. You can use a physical drive letter from your local computer and a path, or a Universal Naming Convention (UNC) path like \\server\sharename.
