NICE TOOL.
The "Services" / "User profiles" optimizations you have are WONDERFUL. This is something I have been looking for for a long time.
ONE SUGGESTION:
Over time since I have installed Vista, I have gone in and disabled some services to "hand" optimize things. (I.e., set some things to DISABLED.)
BUT now when I use your tool, it gives errors because it can not start and/or stop various services.
It could ask in a popup the first time if you can enable it. I wouldn't mind just letting it enable them again so that the tool works better.
Another option would be to ask if you can install a default set of services and their states.
ALSO: There should be different levels of networking. You have machines that need the internet. You also have machines that need OTHER things like file sharing etc. And some that might need NetBIOS, or Server/Workstation etc etc etc. (Hopefully this gives you the idea I'm trying to communicate.)
NOTE: I am using the download version of the program. I should pay and get the commercial version and try that out also. (This appears that the commercial version might allow the granularity I am asking for in the paragraph above this one.)
