SYMPTOMS
When you start a Windows Vista-based computer, you receive the following Windows warning message in the notification area at the far right of the taskbar:

Windows has blocked some startup programs.

Windows blocks programs that require permission to run when Windows starts. Click to view blocked programs.

Note You can see a list of blocked programs and services by following these steps:
 * 1) Click the Blocked startup programs icon that is in the notification area.
 * 2) Point to the Run blocked program menu list. The programs and services that have been blocked from starting are located here.



CAUSE
This issue occurs because a program or a service that has User Account Control (UAC) restrictions tries to start during the Windows Vista startup process or logon process. To simplify these processes, Software Explorer blocks programs or services that require UAC confirmation from running.



RESOLUTION
To resolve this issue, use one of the following methods.

Method 1: Run the blocked program or the blocked service
After Windows Vista starts, you can run any blocked programs or blocked services by following these steps:
 * 1) Click the Blocked startup programs icon that is in the notification area.
 * 2) Point to Run blocked program, and then click the program or the service in the list that you want to start.

If you are prompted for an administrator password or confirmation, type the password, or click Continue.

Method 2: Disable the blocked program or the blocked service
To disable a program or a service during the Windows Vista startup process, follow these steps:
 * 1) Click the Blocked startup programs icon that is in the notification area.
 * 2) Click Show or remove blocked startup programs. This starts Software Explorer in Windows Defender.
 * 3) Locate, and then click to select the startup program or the startup service that is in Software Explorer.
 * 4) Click Disable, and then click Yes in the confirmation dialog box.

Method 3: Remove the blocked program or the blocked service from the startup process
To remove a program or a service from the startup process completely, try to use the Programs and Features item in Control Panel. To do this, follow these steps:
 * 1) Click Startvistastartbutton.jpg], type appwiz.cpl in the Start Search box, and then press ENTER.
 * 2) Click the program in the Programs and Features list, and then click Uninstall/Change.

If you cannot remove the program by using the Programs and Features item in Control Panel, you can remove the program from the startup process by using Software Explorer. To do this, follow these steps:
 * 1) Click the Blocked startup programs icon that is in the notification area.
 * 2) Click Show or remove blocked startup programs. This starts Software Explorer in Windows Defender.
 * 3) Locate, and then click to select the startup program or the startup service that is in Software Explorer.
 * 4) Click Remove, and then click Yes in the confirmation dialog box.



MORE INFORMATION
For more information about Software Explorer, follow these steps:
 * 1) Click Startvistastartbutton.jpg], and then click Help and Support.
