Be aware, i realized some tests on a VM, when you move KB961742-v3 to HFSVCPACK_SW1, at the first startup of windows when you logon, the my documents window open up. And each time you logon this window appears... This KB is definitely strange. A solution is to make a cab in HFGUIRUNONCE to install silently at first logon. Like Mim0 said, if you don't use WinXP on a VM under Win 7, don't use it
