Hello friends, I was playing around vista sp1 setup today and tried to stop system assessment test running at 1st logon ( winsat.exe ). I am talking about Skipping the test, not completely removing it using vlite. what i did to stop it is just simple. 1). made changes in install.wim and moved winsat.exe from system32 folder to elsewhere. 2). added a command to copy winsat.exe to system32 folder at 1st logon in answer file. now, system assessment test runs before the command executes, so u will hear an error sound at 1st logon, which mean setup unable to find winsat.exe and will skip it from running. after it, winsat.exe will be copied to its original location. u can now run system assessment test after logging in vista. this is to save time of installation. as generally we have to re-index system rating after installing newer drivers. one disadvantage of bypassing this test is that one have to enable AERO theme manually. everyone know this! hope this info is useful for some of u ppl. plz share it if there are any other better ways to skip system assessment test with Aero theme working on 1st logon.
