After the 2nd run you should get a message that the system is optimized. At this point the defrag.exe runs ans optimizes the boot. contact the IT admin and ask him which GPOs they apply and he should try to optimize (run them asynchronously if possible, don't use logon scripts) them. Hi well it doesn't say that for me and if I change the Sysmain start value back to the default I cant get past the first reboot it tells me it gave up waiting for prefetcher. Could there be something more that needs to be turned on? I have even tried this http://www.sevenforums.com/performance-maintenance/283057-solution-gave-up-waiting-win7rtm-physical-prefetcher-problem.html but it doesn't seem to fix it. Its also where I found that changing Sysmain start value is pointless.
