There were a lot of updates released this month.  A lot of the updates from Microsoft overlap each other.  There is even a case of one patch replacing another within the 13 patches released this month.  Here are some things to know as you continue through your patch process:

Several patches may apply multiple times to the same system.  MS15-044 applies to multiple products including the OS, .Net, Office, Lync, and Silverlight.  MS15-047 for Microsoft Silverlight is another update that overlaps what files are being updated.  MS15-048 for .Net is also overlaps many of the other updates and could show missing multiple times on the same system.

MS15-052 is replaced by MS15-055.  On Windows 8 and Server 2012 you need to install 052 before 055.  With Shavlik Protect you would just see MS15-055 in this case as it replaces MS15-052.

MS15-043 (Cumulative IE) includes additional defense-in-depth updates to help improve security-related features.  For systems with IE7 and earlier, the JScript and VBScript vulnerabilities are resolved through MS15-053.

MS15-045 resolves two vulnerabilities that have been publicly disclosed, which increases the risk that they will be exploited significantly.

MS15-050 is vulnerable on Windows 2003, but there is not updated offered for this OS as the changes required would require significant re-architecture.  As 2003 reaches its End-of-Life the number of unpatched vulnerabilities will increase.

MS15-055 resolves vulnerabilities in Schannel, but also includes additional security-related changes to TLS including increasing the minimum allowable DHE key length to 1024 bits.
