I have Win7AndW2K8R2-KB3134760-x64.msu, which is a Windows update. I'm trying to do a silent install, but it won't install it. When I run the batch file (see below), it opens and closes immediately. The msu file is located in the same folder as the batch file.
start /wait ".\Win7AndW2K8R2-KB3134760-x64.msu" /quiet /norestart
