Focus follows mouse under Windows

Back to Windows, many more tweaks coming I fear. Let's start with Focus follows mouse. There is an accessibility setting in the control panel but it also raises the window. If you don't want this, use regedit, navigate to HKEY_CURRENT_USER\Control Panel\Desktop and add 0x1 to the key UserPreferencesMask (0x41 would be FFM with raising). Documentation can be found at technet. In order to be able to use this (yes it's unusable that way), add another dword-key called ActiveWndTrkTimeout that has the timeout in miliseconds. There are a lot of guides that call it ActiveWndTrackTimeout or ActiveWindowTrackTimeout, both of which don't do anything!
