Local software installation and the write filter
When you manually install K2 client software at the local K2 Summit Production
Client or K2 Solo Media Server, the installation program helps you manage the write
filter. Both the uninstall program and the install program have the same behavior.
When you run either the uninstall or the install program, the program behaves as
follows:
• If the write filter is enabled, the program notifies you and sets the writer filter to
disabled, then prompts you to restart. To continue the uninstall or install process,
you must restart and then run the program again, this time with the write filter
disabled.
• If the write filter is disabled, the program sets it to be enabled so that after next
restart the K2 system starts up with the write filter enabled.
In this way the write filter is disabled while software is installed. Changes made to
system settings or to the system drive before the restart following an install are
preserved.
Once you have uninstalled or installed K2 Client software, at the next restart the write
filter is enabled. If you want to keep the write filter disabled after an install, run the
Write Filter Utility and disable the write filter before restarting.

SiteConfig software installation and the write filter
When you use SiteConfig to install K2 client software on a K2 Summit Production
Client or K2 Solo Media Server, SiteConfig helps you manage the write filter. The
SiteConfig "Lock" feature enables the write filter and the "Unlock" feature disables
the write filter. In addition, both uninstall deployment tasks and install deployment
tasks behave the same way in how they manage the write filter, as follows:
• If the write filter is enabled (the K2 system is locked), SiteConfig does not allow
the task to be deployed. To deploy software, you must first disable (unlock) the
write filter on the K2 system.
• If the write filter is disabled (the K2 system is unlocked), when the deployment
task completes SiteConfig keeps the write filter disabled. If you then restart the
K2 system, the write filter is still disabled after the restart. This allows you to
deploy additional software.
When you are finished deploying software, use SiteConfig to enable (lock) the write
filter on the K2 system.
