Yes, like I said the problem is the following: With IE 10 under Windows 8, the "Version" says "9.10", but "svcVersion" says "10.0". I do not know how this will be when installing IE 10 on Win7 or Vista. Please test this: function getIEver() { position="wmi.js"; whatfunc="getIEver()"; IEver=WshShell.RegRead("HKLM\\Software\\Microsoft\\Internet Explorer\\Version"); if (IEver.substr(0,4) == "9.10") { IEver=WshShell.RegRead("HKLM\\Software\\Microsoft\\Internet Explorer\\svcVersion").substr(0,4); } else { if (IEver.substr(1,1) == ".") { IEver=IEver.substr(0,3); } else { IEver=IEver.substr(0,4); } } return IEver; } This should now check if IE version is 9.10, which it is on my Win8 system. If yes, it uses the svcVersion instead. If not, it checks if the version is "x.x" or "xx.x" to cut it down properly. (If the version value is later on modified by MS, perhaps they just forgot it. ^^)
