Obtaining the hotfixes
Since these are hotfixes and not regular updates, you won’t be offered this update via Microsoft Update but will have to request it. You can do this at the information page of each hotfix.
If you are not (seriously) effected by any of these issues, it is recommended to wait for the next Service Pack or regular Rollup Update which will most likely contain all these fixes as well.
