Sorry, no idea where to put this. I just recently learned how to use dism. I use it to slipstream all hotfixes and ie10 ect into an AIO install disc. The problem is, it creates a huge install.wim after 8 index mounts and slipstreams. Considering all 8 images use the same darn wim and files, don't know why it has to increase the wim size by 1gig. Either I need to figure out how to use the same wim.install file for all indexes, or I need to compact the wim file which is now 4gbs with ie10 and all updates to April. Any way to do either?
