Hi, I bought a toshiba satellite laptop a couple of weeks ago. It came with Windows 7 Home Premium x32 bit edition. So I reinstall Windows 7 Ultimate x64 edition with the toshiba oem source. However, when I perform the windows 7 update, the critical updates without issues, but when I tried to update some of the language packs, it fails. This also happens on some of the hardware optional updates like the realtek wireless driver. Anyone know why? Thanks.
