Users who cannot wait until Microsoft Internet Explorer 8 RC1 is officially released can download the setup routine directly from Mediafire (32-bit XP, 32-bit Vista) thanks to Devrexter who posted the links on his website.

The download will install the setup for Internet Explorer 8 RC1 which will remove prior versions of Internet Explorer 8 from the system before starting the installation. It will also download and use Microsoft’s Malware tool to check the system for malware.

Internet Explorer will be ready after one or two system restarts. It should be noted that the build number of the Internet Explorer 8 RC1 download is lower than the build number of the release that shipped with the Windows 7 Beta.
