How to troubleshoot configuration errors by using the System Configuration utility in Windows XP,vista, 7, 8 & 10.

Concerned about why your Windows 7/Vista/XP PC takes so long to boot when you switch it on? One of the main reasons is due to the number of programs that run at system startup - and this is the place for you to identify and disable them. Such programs typically (but not always) include an icon in the System Tray in the bottom right-hand corner of the screen - next to the clock.


  Use for System restore
You can use the System Configuration utility to perform a system restore. There are three possible restore points:

• System checkpoints that Windows schedules
• Manual restore points that you specify with the System Configuration utility
• Installation restore points that occur before you install a program or a service

You can use the system checkpoints or the installation restore points to restore your computer's settings to a date when it operated correctly. This may also help determine the cause of the configuration error.

To perform a system restore, follow these steps:

1. Click Start, click Run, type msconfig, and then click OK.
2. On the General tab, click Launch System Restore.
3. Select Restore my computer to an earlier time, and then click Next.
4. Calendar dates in bold are possible restore points. Click the most recent one to view system restore information.
5. Select a system checkpoint or an installation restore point, and then click Next.
6. Close all other programs.
7. To start the system restore, click Next.
8. Your computer restarts.
9. Repeat steps 1 through 8 until you fix your configuration issue.

Using the System Configuration utility
Windows XP

    Start the System Configuration utility by clicking on Start » Run.

    In the Run window, type msconfig and then click OK

    The System Configuration Utility window should now appear. Click on the Startup tab.

    You should now see a window similar to the one below.

    This is a list of every program that starts when Windows is loaded. To disable a program, simply un-check the box next to it. If you are unsure if a program should be disabled, please either look it up on ProcessLibrary.com or contact the Help Desk for assistance (See Get help from the DoIT Help Desk).

    When you are done, click OK to apply the changes. After you click OK, click on Restart when asked about restarting your computer.

    After your computer has restarted and you have logged back in, check the box next to Don't show this message or launch the System Configuration Utility when Windows starts and then click OK.

Windows 8, 7 & Vista

1. On your keyboard, press the Windows key (the Apple key on Macs using Boot Camp) and R at the same time.
   
2. In the Run window, type msconfig and then click OK
   
3. Click on Continue if a User Account Control window appears.
   
4. The System Configuration window should now appear. Click on the Startup tab.
   
5. You should now see a window similar to the one below.
   
   
   
6. When you are done, click OK to apply the changes. After you click OK, click on Restart when asked about restarting your computer.
   
7. After your computer has restarted and you have logged back in, check the box next to Don't show this message or launch the System Configuration Utility when Windows starts and then click OK.
   
   
   Click Start (Start>Run in XP), type regedit, and press ENTER. If you get a User Account Control message, click Yes.
   Once you're in the Editor, navigate the left pane, as if it was Windows Explorer, to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\MSConfig\startupreg.
   Now it's time for another precautionary backup. But this one only protects the items that you're going to delete. In Regedit's left pane, right-click the startupreg key (a key is Regedit's equivalent of a folder), and select Export. Save the file.
   

   

   Now expand the startupreg key by clicking the little triangle to its left. You'll find keys below it for all of MSConfig's unchecked autostarters. To remove one, simply right-click it and select Delete.
