Windows 7 recent items start menu odd problem

[kiemra]

Hi, just installed windows 7 ultimate. I have an odd problem with the recent programs in the start menu. The recent programs are showing except for some exceptions. The programs that are pinned to the task bar don't show in the recent programs until I unpin them first, If i pin them to the task bar again, they dissapear from the recent programs in the start menu. Also other programs like "windows update" or "uninstall a program" don't stay in the recent programs list. Not sure if this is a part of windows 7 or something here is messed up, but I think this hasn't happened before with other windows 7 machines I have worked with. I have tried the several methods I found on the web to repair the recent programs in the start menu like fixing the registry by changing certain value to 3, also start menu properties, restoring jump lists, etc. But nothing changes this. Any idea?

Thanks.
