Manual removal

Please follow the instructions below if you would like to remove AutoStartup manually. Please notice that you must follow the instructions very carefully and delete everything that is mentioned. In most cases the removal will fail if one single item is not deleted. If AutoStartup remains on your system after stepping through the removal instructions, please double-check by stepping through them again.

  1. Start the registry editor. This is done by clicking Start then Run. (The Run dialog will appear.) Type regedit and click OK. (The registry editor will open.)
  2. Browse to the key:
    'HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Run'
  3. In the right pane, delete the values called 'AST' and 'AStart', if they exists. Notice that the values should look exactly like described here, taking lower- and upper-case letters into account.
  4. Exit the registry editor.
  5. Restart your computer.
  6. Start Windows Explorer and delete:
    Note: %WinDir% is a variable (?). By default, this is C:\Windows (Windows 95/98/Me/XP) or C:\WINNT (Windows NT/2000).
    Note: %SystemDir% is a variable (?). By default, this is C:\Windows\System (Windows 95/98/Me), C:\WINNT\System32 (Windows NT/2000), or C:\Windows\System32 (Windows XP).
