If the program(s) you are attempting to uninstall come with an uninstall wizard, you should always use that before using Add/Remove programs wizard in the control panel. Uninstall wizards will remove every reference to the program in question and actually delete the folder(s) the program was stored in. Using the Add/Remove program does not really remove the program, it resets all the operating system's pointers to the program only, the folder and program still exist on the computer. If the method you used was the Add/Remove Program option in the control panel, you will also need to goto the Start, All Programs, find the entry there, right click it and select delete to remove the reference there. Then goto where the programs are stored, typically C:\Program Files, locate the folder and delete it. Now that all this is done, goto the Recycle bin on the desktop and empty it. As a final step, reboot the machine to make sure everything is reset and removed.
If after all this you find the programs are listed on the left side of the start menu, right click someplace on the taskbar that isn't populated, select properties, then select the start tab at the top, find the Customize button and select it. In the next window you can detail how many programs will list in the quick start area, you will see a button that says Clear List. Pressing this button will remove all the programs listed on the left side, don't panic, The non-deleted programs that were there will reappear as you continue to use them, the operating system uses that area to display frequently used programs.
