Initially Microsoft released Internet Explorer 10 only for Windows 8 as part of it. Being directly integrated into the system, many users have questioned Microsoft’s decision not to make the 10th version of the browser also available for Windows 7 a year ago. As a consequence to this, it was imminent the Windows 7 version to be available in this period of the year.
At a first look, the Release Preview of Internet Explorer 10 is nearly identical to the version of the browser integrated into the Windows 8. The only core difference is that Adobe Flash is not integrated into the Windows 7 / Windows Server 2012 version like it is in the Windows 8 version. The reason of having a built-in version of Adobe Flash into Windows 8 version of IE 10 is that the browser does not support browser plugins.
In case you want to try out the browser in Windows 7, you should know that the installation of Internet Explorer 10 Preview will replace the current version of the browser on the system. A restart will be required to complete the installation. If you are not satisfied with its functionality, you can uninstall it from the Updates panel of your operating system.
