Simplix UpdatePack enables you to update your live Windows 7 System as well as integrate hotfixes into a Windows 7 distribution.

This update pack allows you to update Windows 7 SP1 (x86 x64) and Server 2008 R2 SP1 live operating systems, as well as to integrate the updates in the distribution (Install.wim). It can be installed in any language. Includes all critical, recommended, and security updates and updates for all versions of Internet Explorer.

To install updates on Live Windows 7 System:

Key /Reboot to automatically restart if it is needed.
Key /S for a fully silent install with no windows and messages. Case is significant.
Key /Silent for passive installation - you can see the progress, but the installation is fully automatic.
Key /IE11 installs Internet Explorer 11 and its localization (optional).
Key /Temp= allows you to specify a work location (optional).
Key /SmartFix integrates smartfix program by Simplix in the System Restore. File SmartFix.exe must be placed together with the Pack.

To integrate updates/hotfixes into Windows 7 distribution (install.wim):

These switches are designed to integrate the updates in this distribution:

Key /WimFile= specifies the location of wim-file; you must specify an absolute path.
Key /Index= indicates the index system in the wim-file for each index must be performed to re-integrate.
Key /Index=* allows you to integrate updates to all indexes in wim-file.
