I went through one of those idiotic "tweaking the XP services" tutorials on the web a couple of months ago and have had a hell of a time installing certain applications ever since. It was nigh on impossible to get IE7 to install, I can't get a Sony DVD editing/burning software to install nor can I get Sandboxie to install. Is Sandboxie difficult to install? It does have a kind of throw in the towel message on its installer about trying F8 (safe mode) as a second option... Can you guys think of any services under "My computer" > "manage" > "services" that I might have turned off or to manual after going through the moronic tutorial that I might need to turn back on or set to automatic? Thanks B.
