Just upgraded Vista to Windows 7. Upon checking W7 updates, I saw that there was a 69Mb update for Service pack 1. I opted to download and install it and after installing the update, I get the following error message..."Failure configuring service pack....reverting changes". Researching the web shows several issues. I would like to know what the "experts-exchange" experts believe to be the quickest way to resolve this without having to reinstall W7. Thanks in advance for your answers.
