4Things to Know
5Required Hotfix
Before installing the service pack, the installer adds a needed hotfix to the operating system. KB955430 is a Servicing Stack Update that “handles installation and removal of software updates, language packs, and optional Windows features.” WSUS users should note that this hotfix must be predeployed before SP installation via WSUS can proceed.

SP2 includes a cleanup command called “compcln.exe” that will remove the previous versions of files that have been updated and replaced in SP2. Running this command recovered about 330MB of space on my system. However, I do not recommend running this command if testing the RC on an in-use system. Users cannot overwrite the gold code for the service pack over this RC-they must instead uninstall the RC first. But “compcln.exe” removed the ability to uninstall the service pack.
