I have a Razor mouse ( the Lachesis) which has the ability to store profiles -of polling rates and DPI- and switch these profiles as it sees the desired program. I use two profiles. One is for the "Steam.exe" for my on-line gaming. When I launch Steam, the mouse sees the exe, and switches to this max polling/DPI profile. The other profile is the "Normal" profile which is set at a much slower, less twitchy speed. On XP, I was able to find the Windows "Explorer.exe" in C\Windows\System32. I set this as my switching exe.and it caused the mouse to switch to the "Normal" profile when it saw the desktop. I can't find the "Explorer.exe" in System32 in Windows 7. Is there no such thing in Windows 7 (Enterprise) or is there another exe. I can use for the same purpose of switching, on seeing the desktop?
