You must have User Account Control (UAC) ON. You will have to turn it OFF
then make your changes and save them. When you turn UAC back on you will
reboot your computer and your settings should be stay.

Goto START/CONTROL PANEL/USER ACCOUNTS and click on the "Turn User Account
Control on or off" link, then uncheck to UAC box and click the OK button.
You will have to reboot.

I have been experiencing the same sort of issue with mouse settings, system
icon in the notification area of the task bar (volume, network, power, etc.),
etc.
I have tried disabling the UAC, rebooting, changing the settings, rebooting,
re-enabling UAC, rebooting... but those settings do NOT stay where I need
them. This is very frustrating.
Anyone have any other suggestions why this is happening?
