Service Packs and Patch Installation

In this section:


User Workspace Manager products can be patched using a Windows Installer patch. A patch is an MSP file that, when installed, updates files and registry keys on an existing installed product. Installing an MSP can reduce system downtime because reboots are not always required. User Workspace Manager product patching gives all of the usual benefits associated with Windows Installer Patching, including ease of deployment and the ability to roll back to an earlier version. Patches include the following:

  • Public Hotfix - Issued publicly on to address a widely reported issue and should only be installed to address the specific problem. Public Hotfixes are cumulative in that they contain all previous hotfixes. Public Hotfixes are distributed as an MSP.
  • Service Pack - Contains all of the fixes from the last Private or Public Hotfix and any Service Packs, plus any fixes that have been found for which a Private or Public Hotfix was not issued. Service Packs are cumulative in that they contain all previous Service Packs. Service Packs are distributed as an MSP.

    If a Service Pack is part of the product release media, the installer automatically installs them. Service Packs can also be installed or deployed using the same technology and techniques used when installing MSIs. Both Microsoft System Center and the Management Center can deploy MSPs. If neither of these products are available, service packs can be installed using the command line interface.

Installation Order and Dependencies

It is recommended that all components of a service pack are installed and that the PersonalizationServerXX.MSP is installed first. All other components have no required install order.

To view previously installed patches, navigate to Control Panel > Programs > Programs and Features > Installed Updates.

Manage Patches with the Management Center

To install a patch using Management Center you must first upload the MSP and then assign it to a deployment group for deployment to the endpoints.

Manage Patches Using the Command Line

User Workspace Manager patches can be installed from the command line as well as from the Management Center.

It is recommended that logging is switched on when using the following commands. To enable Logging add /l*vx Patch.log immediately after the /i or /p. For example: msiexec.exe /i Agent.msi /l*vx Patch.log

Roll Back Service Packs

There are two ways to roll back, or uninstall, User Workspace Manager Service Packs:

  • Using the Windows Control Panel
  • Using Management Center

If a service pack is uninstalled, the installation reverts to the previous latest build, whether a service pack or base version. All agent and console service pack components except the Personalization Server component patch file (PersonalizationServerXX.msp) can be uninstalled
