I'm rebuilding my desktop PC with a fresh installation of Windows 7 x64. Upon first boot after installation, 3 updates automatically installed. After a reboot, I was informed that over 100 additional recommended updates (and quite a few optional updates) were ready to be installed. Are there any known issues with installing so many updates at one time? I chose to install all of the recommended and optional updates (except for the 39 international updates). During the Windows Update installation process, a Microsoft Mouse and Keyboard Center installation window appeared. When the progress bar got to about 75%, however, the following error dialog appeared underneath: Microsoft Visual C++ Runtime LibraryThis application has requested the Runtime to terminate in an unusual way Presumably, the installation of the Microsoft Mouse and Keyboard Center (and perhaps other items) failed to install; upon pressing the OK button, I was informed that 51 updates succeeded and 75 failed. Codes 800706BE 800706BA were mentioned. Upon reboot, another batch of updates (75?) installed; then the PC rebooted twice. At this point, Windows 7 appears to be completely installed and up to date. There are no new items in Windows Updates. However, the Microsoft Mouse and Keyboard Center is nowhere to be found; I was able to download the installer and successfully install the product. Is my experience typical?
