Link to hotfix: KB2956985

This hotfix appears to be a feature release in the guise of a hotfix.  It includes all previous hotfixes, including the mysterious Hotfix 3.

The hotfix included changes the following problems from Hotfix 3:

• DeploymentConfig.xml file: If you entered direct registry entries in tis file and use DWORD/QWORD/Multistring values, they were not set correctly.
• When logging on to the client that is receiving publishing from an App-V Publishing server, PowerShell windows could be seen on the taskbar briefly.  Clicking on these could interfere with the publishing process.  These windows are now hidden.
• Under different circumstances, the App-V client can crash when using Config Manager 2012 SP1 or R2.

NOTE: There is a known issue with the client hotfix that it changes (disables) the Shared Content Store Mode configuration setting in the client (unless Group Policy is used).  Beware.
