Hey, im still having issues. The thing i did with a custom install worked but its not stable laggy and i cant install VMware tools directly.When you're in VMware, don't forget to disable any auto-install "helper" features. You should create a plain VM, without informing VMware that you have an ISO image. VMware will try to inject changes while Windows is installing, and you want to avoid that.
If followed correctly, no repair action is required for installing a custom ISO, much less a clean ISO. I'm using VMware Workstation all the time when testing user's questions.
