In answer to a previous question on superuser someone suggested setting a registry key to read-only.

But when I look at the permissions there are four (but one of them 'RESTRICTED' I assume is irrelevant so I'll ignore it)

There's 'SYSTEM'

There's Me (I'm an admin)

There's Administrators (which I assume is the 'default' administrator)

I don't know which one of these to change to make a key read only (so that windows itself can't alter it unless I change its permissions back)

I don't seem to be able to change the permissions on anything but the 'RESTRICTED' user.

My goal is to stop windows from changing certain keys back to their default settings when the computer reboots. If it matters the specific keys I want to set to be unchangeable by windows are...

HKEY_CURRENT_USER\Control Panel\Mouse\MouseSensitivity

and

HKEY_CURRENT_USER\Control Panel\Mouse\SwapMouseButtons

Thanks. Do you know which of the mentioned users I make the change to? – MrVimes Aug 28 '10 at 21:36
I'd change them all if you want it to be read-only (though you could experiment). Make sure that Read access is still available for all. – BillP3rd Aug 28 '10 at 21:41
