Also having the same issue with KB2760411, KB2760588 and KB2760583 apparently installing and then being offered the same installations again. I am running Windows 7 and Office 2007. The updates are:
KB2760411 - Security update for Microsoft Office 2007 Suites
KB2760588 - Security update for Microsoft Office 2007 Suites
KB2760583 - Security update for Microsoft Excel 2007
I was having a similar problem with 2 updates for a long time last year - probably about 6 months, before I came to this forum and found the following thread to resolve it. Don't know if the issue is similar this time around but that one was related to a conflict between Microsoft .NET version 3.5.1 and version 4.
