ATF-Cleaner would have cleaned out the Temporary Internet Files folder. I was probably being over cautious. However if you want to put your mind at ease do this:

Click Properties then Disk Cleanup
Ensure Temporary Internet Files, Recycle Bin, Temporary Files are ticked. The rest are optional.
Click OK then Delete Files at the prompt.
