Yes, but Parseus noticed that it fixes audio problems (and it's just a hotfix which will not be listed by default by the file-checker)
BTW, 888111 is NOT intended for XPSP3. It will refuse to install if running XPSP3. The KB article specifically mentions SP1 and SP2, but NOT SP3.
I frequently look into the download-center (new downloads) and there I found it.
Where did you get 2616310? MU is not asking for it. Only 2544893 and MRT (which you seem to have forgotten all about)
And MSRT... I didn't forgot it but yesterday evening - when I updated the XP-list and file-checker - the new MSRT was not released.
