I checked one file on Windows 7 64 bit machine and file has these details
Lsasrv.dll - 6.1.7601.22843
This version is from MS14-068 or 74 which were installed at the same time as MS14-066. Within MS14-066 version of the file is 22814. Patch assesment should detect version >22814 and mark KB2992611 as installed
Some of customer's PC has version 18637 and these PC reported patch as installed and not trying to install patch again
So I think the problem is in 22xxx - LDR on Win 7 64 bit
On Win 7 32 bit I have checked one machine and Lsasrv.dll has version 6.1.7601.18637. This is from MS14-068 which was installed. Maybe rule for KB2992611 is not correct for 32 bit Win 7?
