I am currently midway through the Win 7 optimize guide by Nick_N, and have run TweakPrefetch.exe and made the changes, confirmed with WinPrefetchView that I have the correct and only file in the top pane, then run TweakPrefetch again, Options/Advanced Controls, and gone to Tools, but can not see the option "Rebuild Layout", only a "Fetch Configuration Wizard" which seems to have little reference to what I'm looking for. Can anyone tell me where I am going wrong, and what effect not rebuilding the layout would have if I can't find out what is happening?Thanks, Bruce.

Got it to work, not sure why or how, but the option to rebuild this file is now available.Thanks, Bruce.

Any link for this "guide"? I'd like to try it, if I can get ****ing FSX reinstalled!!!!

Hi,Here's the link, the article I am using is about half way down the thread. However, I could always run FSX with no troubles in Win 7 (64) before I started this optimization, this is only to get improved performance. if you have trouble even running FSX then you there may be other issues.http://www.simforums.com/forums/forum_posts.asp?TID=34141&PID=198077#198077Thanks, Bruce.
