On a Vista Home Basic desktop system, the update KB941649 caused the system to blue screen on reboot when it was applied with several other updates. The Winboot.exe file would be missing from the system32 folder. Going through the repair action when booted from the install DVD would fix this problem until the updates were again applied. I then applied all the updates that were pending individually, but KB941649 would always fail with the error code of 0x80041002. I could not find any reason in the log files or in the update forums for this error. I have hidden this update for now and don't think it really will effect me as it appears to be primarily for mobil systems - this is on a desktop, but am concerned that future updates may also not apply if this one is a prereq to one of them. Anyone have any suggestions on finding the cause, or of potential problems down the road if I leave it hidden?
