can i have some light on update KB2574819 (Update for Windows 7 for x64-based Systems) this update first got Synced from SCCM (SUP) but doesnt deploy to systems. manual download from MS site and its installation works though... is it because MS re-released it with V2 (V2 is the one which is available for download now Windows6.1-KB2574819-v2-x64.msu) http://support.microsoft.com/kb/2574819/en-us
