when I drag an icon to taskbar, there is one option (close window)how can Re-enable,(pin to taskbar) option.

You can use a right-click on a desktop icon, select "pin to taskbar", done. If you drag an icon to the taskbar, a right-click on it should show two choices "close windows" and "unpin from taskbar". I'm not sure how one could enable/disable those options.Mobile AMD64 3000+, VIA Apollo K8T800 chipset, 1 G RAM, ATIRadeonMobility 9700, 20x DVDRW, C:XPSP3 (55G),D:WIN7 (25G),F:DATA (250G)

Some shortcuts to specific files cannot be pinned such as Control.exe, install.exe, rundll32.exe etc. Also shortcuts with keywords like Documentation, Help, Install (etc.) cannot be pinned. So what is the name of the shortcut and its target program?
