Windows 7 Hardening Steps – the things you need to do after installing updates KB2269637 KB2719662 MS15-124.

Windows Updates… the bit you need to do after installing them!

Bit of an FYI post really for the following updates KB2269637 KB2719662 MS15-124. The below are some Windows 7 hardening steps that are needed after installing Microsoft updates KB2269637 KB2719662 MS15-124. I see these a lot in organizations. Admins have installed all the patches however haven’t followed through with the extra steps that are needed. There are only a few updates that require some extra action. In most cases its a registry key that needs adding or modifying. In mosat cases these can be achieved through Group Policy. The below list isn’t all of them just a couple I have recently come across.

MS KB2269637: Insecure Library Loading Could Allow Remote Code Execution

REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager" /f /v CWDIllegalInDllSearch  /t REG_DWORD /d 0x1

MS KB2719662: Vulnerabilities in Gadgets Could Allow Remote Code Execution

REG ADD "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Windows\Sidebar" /f /v TurnOffSidebar /t REG_DWORD /d 0x1

MS15-124: Cumulative Security Update for Internet Explorer (3116180)

REG ADD "HKLM\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_ALLOW_USER32_EXCEPTION_HANDLER_HARDENING" /f /v iexplore.exe /t REG_DWORD /d 0x1
REG ADD "HKLM\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_ALLOW_USER32_EXCEPTION_HANDLER_HARDENING" /f /v iexplore.exe /t REG_DWORD /d 0x1

Test and test again to ensure compatibility and that these work in your own environment, they worked for me though on Windows 7 Pro machine.
