Service Packs are self-contained packages or patches that are used to update specific files within a User Workspace Manager application without reinstalling the full application. Service packs can be applied more often and reduce the need for system restarts on your endpoints. Service packs are delivered as a Windows Installer patch (MSP) file and are often referred to as patch files.
In this section:
Service Packs can be installed or deployed using the same technology and techniques used when installing MSIs. Both Microsoft System Center and the Management Center 8 FR4 can deploy MSPs. If neither of these products are available, service packs can be installed using the command line interface.
For example, the command:
msiexec.exe /p ApplicationManagerAgent64.msp
installs any files that have been amended as part of the patch for just Application Control 64-bit agent.
The following command installs the base version of the Application Control Agent (MSI) and the Application Control patch file (MSP) simultaneously:
msiexec.exe /i ApplicationManagerAgent64.msi PATCH=c:\fullpath\ApplicationManagerAgent64.msp
A base version must be installed before the patch file can be applied.
If the patch file contains driver or hook files that are currently in use on the machine the patch is being applied to, you are informed that a reboot is required. If you chose to continue, the system is restarted when the patch has been applied.
Installation Order and Dependencies
It is recommended that all components of a service pack are installed.
There are two ways to roll back, or uninstall Service Packs:
- Using the Windows Control Panel
- Using Management Center 8 FR4
If a service pack is uninstalled the installation reverts to the previous latest build, whether a service pack or base version.
Roll Back Service Packs Using Windows Control Panel
The procedure used to roll back service packs varies depending on the Operating System:
For Windows 7
Navigate to Control Panel > Programs > Programs and Features > Installed Updates. Highlight the selected patch and click Uninstall.
Roll Back Service Packs Using Management Center 8 FR4
- In the Management Center console, select Overview > Deployment Groups tab > Deployment Groups.
Highlight the Deployment Group and select Settings > Assigned Packages.
The Assigned Packages work area displays a list of all the products and their associated packages.
- Highlight the required Application Control service pack and click Unassign from the Actions menu.
Click Review and Submit.
The Submit Changes dialog displays.
- Check the details are correct and click Submit.
The patch is unassigned based on the deployment group Installation Schedule.
