Hi, as per topic, is there any way to remove the blank space or make it resize according to the amount of icons we have on the right side of the start menu? I mean it works perfect for people who have lots of pinned applications but for some users like me whereby I have only like 5 pinned applications, the blank space looks extremely ugly.

Right click on the Windows icon, then properties, then start menu, then click "customize" (it'll be next to "Start Menu"). You can remove them there.

Ah, sorry to have confused you. I mean the blank space as in the screenshot:

On windows XP, the blank space is resize-able, but on Vista, it doesn't matter how many applications you have, it remains the same Any work-around?

For the right side, you simply have to add more items (right click and pin them). For the left, do what I instructed above. If it doesn't work, then I guess your items have to reach that space or it'll be blank space.

Change the amount of recent programs that are allowed to be shown in the startpanel

you are completely missing what he is asking for.
