Preventing Software from Loading at Windows Vista Startup

  • PrintPrint
This document applies to HP and Compaq desktop computers with Microsoft Windows Vista.
Many software programs on a computer open automatically and are not apparent while working in Windows. Some of these programs are necessary and cannot be changed or removed. Some should be opened only as needed. Others might not be needed at all. One thing all software programs have in common is that they take up processor time and space in memory. This document explains how to determine which software programs might not be needed and how to prevent them from starting up.

Uninstalling unnecessary programs

Removing unnecessary software programs prevents them from starting and gives the hard drive more space. Do the following to remove unwanted programs:
  1. Click Start , and then Control Panel.
  2. Under Programs, click Uninstall a program.
  3. Examine the items that appear inside the Uninstall or change a program window closely. The items listed are programs currently installed on the computer.
  4. Select the items in the list that you do not want, and click the Uninstall/Change button.
    NOTE:Do not remove items in the list that you are unsure about. The table at the end of this document contains a list of common software programs to help you decide if an item should be removed or not.
  5. After all items have been removed, close all open windows, restart the computer and go to the next step.

Preventing programs from loading

The following sections provide different ways that software can be prevented from opening automatically when Windows opens.

Using systray icons to prevent programs from starting

Each of the small icons on the system tray, next to the time, represents software that runs in the background. Hovering the mouse pointer over any of these icons reveals the software program name or function. You can increase system resources and prevent possible conflicts by reducing the number of these programs that open with Windows.
Figure 1: System tray icons
Sometimes a software program provides a feature that prevents itself from opening with Windows. To see if a program has such a feature, do the following:
  1. Double-click or right-click on an icon in the tray to bring up more options.
  2. Look for options or selections in menus that will prevent the software program from starting. Select Open, Options, or Preferences and look for anything related to starting up. If you find a setting that enables the program to start automatically when Windows starts, disable it. If the feature is not available, use the next section and the table at the bottom of this page to prevent the software program from loading.

Removing icons from the Startup folder

Some programs open with a shortcut icon in the startup folder (startup icons). Use the following steps to show any startup icons that are hidden and remove startup icons from the startup folder:
NOTE:Removing items from the Startup folder does not uninstall the software application.
  1. Right-click Start , and click Explore. The Windows Explorer window appears with Start Menu already selected.
  2. Click the arrow next to Programs to open the Programs folder.
  3. Click Startup.
    The shortcut icons are listed in the right side pane.
  4. To show icons that are hidden, click Start , Control Panel, and then Appearance and Personalization.
  5. Under Folder Options, click Show hidden files and folders.
    The Folder Options window opens with the View tab open.
  6. To show icons that are hidden, under Hidden files and folders, click Show hidden files and folders, and click OK.
  7. In the Startup view, click an icon from an unwanted program on the right side of the window, and drag it to a blank area on the Windows desktop. Release the mouse button to drop the startup icon onto the desktop.
  8. Continue dragging and dropping unwanted startup icons until all unwanted startup icons are on the desktop. Click Yes to any window that pops up asking to confirm the removal of a read-only file.
  9. Close Explorer and restart the computer for the changes to take effect. Delete the startup icons that were moved to the desktop after you are satisfied with the way the software programs are working.
    If you find that a particular software program should not have been removed from the startup folder, double-click the startup menu item to open the startup window, and drag and drop the startup icon from the desktop back into the Startup window.

Using Windows Defender to prevent software programs from starting

Some software programs do not place a small icon in the system tray while running. Perform the following steps as an alternative to preventing software programs from starting when Windows opens.
CAUTION: Disable only those items that you know are unnecessary. Disabling programs a device needs might cause the device to not function. For example, you might get a loss of sound, loss of higher colors and graphics modes, and system errors when trying to run programs.
  1. Click Start , Control Panel, Security, and then Windows Defender.
  2. At the top of the window, click Tools.

    The Software Explorer window opens.
  4. In the Category field, select Startup Programs.

  5. In the left panel, select the software programs you do not want to automatically start when your computer starts up.
    Do not select any items you are not sure about.
  6. Click the Disable button.
    If you are unsure about a startup item, write the name down and research it on the Internet or consult the table at the end of this document . Never disable or remove a task or program if you do not know what it does.
  7. At the dialog that asks if you are sure you want to disable the application, click Yes.
    The tasks or programs selected in the previous steps will not load when Windows restarts.
  8. To re-enable the program or task, follow the steps above, select the programs you want to re-enable, and click Enable at the lower right in the Software Explorer window.
    CAUTION: If Windows or other important software stops working after a checkmark is removed, start Windows in Safe Mode and replace the checkmark. To start Windows in Safe Mode, turn the computer on and when the first screen appears, press F8 repeatedly at the logo screen, and select Safe Mode.

Disabling HP TouchSmart Software

Items that begin with HPTS or HP TouchSmart are related to the HP Touchsmart software. Consult the table at the end of this document . If you do not use the HP TouchSmart software, you can prevent it from opening and running in the background by performing the following steps:
  1. Open the TouchSmart software.
  2. Click Personalize.
  3. Click TouchSmart Settings.
  4. Remove the checkmarks from the Auto-Start and Quick Launch.
  5. Click OK and close the Touchsmart Software.

Reference: Software programs that start automatically and what they do

The software programs in the following table are some of the most common software programs that open with Windows on HP and Compaq desktop computers. It does not list every possible software program that can be loaded onto the computer. If a software program is not on this list, write the name down and research it on the Internet using an Internet search site.
CAUTION:A name in the following list might also be the name of virus or Trojan. Many viruses and Trojans copy a system file name so that unsuspecting people delete a system file that prevents Windows from opening. Use virus scanning and removal software to find and remove viruses and Trojans. Do not rely on this list to determine if a file is a virus or Trojan.
