Hi Alvin,
1. The disk space for the client is not important. The disk space for the Standby is important. For the client, please modify the client as needed. The disk space for Standby must remain the same. If all Windows updates do not fit in the disk space size, this is okay.
2. You are right, there are no options for you to check there. This wording may need to be fixed in the Benchmarking guide. The default setting will be fine.
No, there are no images accompanying the installation of VMmark. Instead, we are very specific in our installation instructions. As you go through the VMmark installation, please follow each instruction completely and exactly.
Thanks,
Rebecca
