A. When you download an Office service pack, you typically get one big file. When we run this file on a client, it's extracted locally on the client then executed. This process can take a lot of disk space and slow down your installation. It's also very annoying if you're virtualizing applications and the service pack application generates a large cache of patches.
You can extract a service pack to a folder using the /extract switch. For example:
<pre>"D:\Software\Office 2007\en_2007_microsoft_office_suite_service_pack_2_x86.exe" /extract:"d:\software\office 2007\sp2"
