    SoftMon.exe is deleting HP print drivers after installing Microsoft Office updates


      Back in December 2014, after pushing out some Microsoft updates, almost everyone in our agency with an HP printer installed had to re-install their print driver.  It seemed to only affect clients on Windows 7 64-bit with Office 2010 32-bit installed and using the HP Universal Print Driver.  I just assumed it was a bad patch from Microsoft and didn't look into it further.


      Then the same thing happened again two weeks ago after pushing out February 2015 Microsoft updates to clients. This time I was able to narrow the problem down to a specific patch: "Update for Microsoft OneNote 2010 (KB2956075) 32-Bit Edition"


      After installing the patch, there are 7 files that end up being deleted from C:\Windows\System32\spool\drivers\x64\3\  -  The files are:


      However, it is not the patch that is deleting the files.  Running Sysinternals ProcMon shows that it is actually SoftMon.exe from LANDesk deleting the files.  This happens a few minutes after the patch has completed its install.  At this point I am not sure why those files are being deleted, but when it does happen, it breaks printers using the HP Universal Print Driver.


      This problem does not happen if I remove the SoftMon component from the LANDesk agent by running softmon.exe /remove.
