Wait, I (already) found a few bugs: First, hfslipc is looking for KB2562937-ENU-xxxxxxx , but my lang is set to spanish, not english. Because of this, it asks for the prev. update (2508272, now obsolete) and it says that 2562937-ESN-xxx is "obsolete", whereas it's actually the correct update. Why on earth would hfslipc ask for a previus update when it doesn't find the current one? I think this is not right. It should just ask for the latest, and if it's not found, then say it's missing, but not ask for a previous one... Second, are you sure that IE8-KB2559049 replaces the Compatibility update (KB2447568)? It replaces the previous cumm. update, but the compatibility update...????? (BTW, it says "relpaced" instead of "replaced"). Third: 2567680 DOES NOT replace 2507938. It replaces 2121546, which was already replaced by 2507938. 2507938 updates two files: winsrv.dll and csrsrv.dll, while 2567680 replaces only one: winsrv.dll I hope you can fix these ASAP. bye!
