--- Comment #149 from Aric Stewart aric@codeweavers.com 2012-02-07 08:54:58 CST --- We are spinning in circles about theoretical situations.
If, as you say, Windows can reset those keys without warning to the user then the chances that users are manually changing them is very small. If that is confirmed the case then I will just have wine automatically regenerate them on every start. Problem solved.
If Users expect to be able to make changes there and have rational results then we cannot do that. Instead we need to put the auto generated things somewhere else and that would confuse, as your point out, programs that look for the key.
We cannot get around auto generating things every run because font situations may have changed since last run and we want to pull in those changes.
