This tweak allows you to bring running programs to the foreground just by moving you mouse of the application window. This is similar to the X-Mouse feature found on UNIX operating systems.

Open your registry and find the key below.

Active window tracking is controlled by the existing binary value called "UserPreferencemask" for Windows 95/98/Me or "UserPreferencesMask" for Windows 2000/XP.

To enable Active Window Tracking you need to add "0x1" hex to the existing value, to force the window to also come to the foreground you need to add "0x41" hex.

If the current value is "be, 3e, 00, 00" using a calculator add "be" (hex) and "41" (hex), the total equals "ff" (hex). Therefore change the value "be" to "ff" and it now becomes "ff, 3e, 00 00".

You can also create an additional DWORD value called "ActiveWndTrkTimeout" under [HKEY_CURRENT_USER\Control Panel\Mouse] which specifies the time (in milliseconds) that the mouse needs to remain over a window before the window is activated.

Restart Windows for the changes to take effect.
