It has been released today. I updated from IE9 and all the issues I had with the preview version seem to have been resolved. My saved cookies through CCleaner now work correctly and do not get deleted like they did in the preview. The browser does seem to be a little faster as well. It will be pushed through Windows Update but if you don’t want to wait you can get it from two different official sites.
I used the second one and it worked perfectly. The first one gives you a self extracting CAB file that probably ultimately gives you the .exe that you can download from the second link.
The second link is for Internet Explorer 10 for Windows 7 64-bit Edition and Windows Server 2008 R2 64-bit Edition, so if you have win7 32bit versions this isn’t for you.
I don’t know if there is 32bit OS version, perhaps better to use the first link and have MS detect your OS version.
Presumably there are as when you visit the first link it detects you Operating System, I tested using XP also. With my win7 starter edition 32bit on my netbook, it offered a download link (declined Bing and MSN).
The file downloaded was EIE10_EN-US_WOL_Win7.EXE is 24.1MB, much smaller than the IE10-Windows6.1-x64-en-us.exe file at 42MB.
If you want to disable it in your browser then the best route is via the Java UI in control panel under the security tab, If you had disabled java in this way then it wouldn’t have been activated again with the install of IE10.
