I may have to change my mind about this thing working. I tried it on another computer and it only worked partially. Some effects were still checked while others were unchecked. However... I think I have figured it out on my own. I exported the settings under [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\VisualEffects] on a newly installed Win XP machine and then checked the radiobutton for "Adjust for best performance" and then did another export. The only difference between the two I could find was this: [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\VisualEffects] "VisualFXSetting"=dword:00000002 I changed HKCU to HKLM and...voilá...it works. Atleast on the three different computers I've tried on so far. It would be nice if someone else could confirm this. /Abusor
