Windows 8.1 was released recently and by default it includes Internet Explorer 11 pre-installed.
With Internet Explorer 11 you must install the CloudShare Remote Access Plugin. This allows you to RDP to your CloudShare VMs directly from the browser utilizing our network acceleration service which provides low latency and reliable connectivity. In addition you will be able to access your VMs using our Java Console plugin.
Please note that currently you will not be able to access your VMs without installing the remote access plugin.
