If you have followed my tip to make Windows Vista run faster, you will receive the following annoying Windows warning message in the notification area at the far right end of the taskbar: Windows has blocked some startup programs.

Windows warning

This problem occurs because a program or service that you have earlier restricted to start using the User Account Control (UAC) restrictions tries to start during the Windows Vista startup process. Although your Windows Vista now may run slightly faster, but the annoying message keeps popping up every now and then. Luckily it is pretty easy to stop this message from appearing again. Let me show you the easiest way to do it.

Right-click on the annoying icon in the system tray, select “Run blocked program” and then “System Configuration Utility”.

The usual UAC prompt will pop up. Click on “Continue” to proceed. Then you will see the following pop up window. Check on the box “Don’t show this message or start System Configuration when Windows starts”.

There you are. You will never see that annoying pop up message again.

There is in fact an article on this problem at Microsoft Support’s knowledgebase site. The page details a few methods which you can use to get rid of that message, namely:

  • Method 1: Run the blocked program or the blocked service
  • Method 2: Disable the blocked program or the blocked service
  • Method 3: Remove the blocked program or the blocked service from the startup process

For details, go to Error message when you start a Windows Vista-based computer: “Windows has blocked some startup programs”.
