Checking the recent Windows Update patches that arrived today I noticed an Office 2007 patch. Generally, that wouldn't be concerning, however I don't have any affected products installed.
I'm running Windows 7 Ultimate x64 with Office 2010 Pro Plus. Office WAS unpgraded from 2007 though.
I have unchecked and hid the update until I can get confirmation that this is a false detection.
If anyone has a contact within Microsoft that could get on this, I'm sure you would be saving a lot of hosed installations should it actually install as it replaces MSO.dll with an older version than Office 14 installs.
Stay sharp out there.
