I don't know - as yet - what you found but I have Windows 7 Home Premium and I tried this, as I have much the same problem. I went through 'Nontek's' suggestion and did what CiG suggested but did not find - or rather the 'edit' part of the programme could not find - "Wait to kill service timeout”. So does anyone know where/what the same command in "Windows 7 Home Premium" is?
Also has anyone else noticed that since installing SP1 that starting up "Windows 7 Home Premium" has slowed down considerably? For instance when I get to the "Welcome" notice the arrow going round and round used to do about 7 or 8 circles before it disappeared whereas now I have counted - on many occasions - it can do this between 30 and 40 times and, very occasionally, has actually gone well over 40 times. Does anyone know why this is happening and if there is anything that can be done about it or is it just something I have to live with?
