Hi Rob,

Other than the WinXP/IE6 VM, I'm not sure why you'd have to download these files more than once. I may not have done a good job of explaining the time limits so I'll try again:

<strong>IE6 VM</strong>: 90 days of continuous use from the time Microsoft uploads it. We'll be refreshing near the expiration date. 
<strong>IE7 - IE10 VMs</strong>: 30 days use with two rearms which give you 90 days of continuous use. After 90 days, the VM works for an hour before it shuts down.

So for IE7-IE10, the same files you downloaded can resued to recreate the VMs. The <strong>ONLY</strong> VM you would have to redownload at is the IE6 VM.

IE marketshare grew this month and IE9 & IE10 are solid, standards-based browsers. The fact that you're saying that IE behaves differently than the standard tells me you haven't checked out the latest versions.
