Information being saved in C:\Users directory?

I also had the same issue with Vista putting items into C:\Users\...VirtualStore\... Rather than move my installs to a different location; I gave "Everyone" "Full Control" permissions on the "Program Files\World of Warcraft" folder. This way any process that runs has access to that folder. Wow patches come down as .exe's and unless you manually run them as administrator; I suspect a lot of patched files end up going into your C:\Users\...VirtualStore\... .

You can set up your user up to be an Administrator and automatically get elevated priviledges when required (normally the UAC bugs you for these elevated priviledges).

This is how I run and I have also turned off UAC as well as the "Everyone" permission on my wow folders. Absolutely nothing in my C:\Users\...VirtualStore\... folder and no annoying UAC popups and everything inherently runs as administrator (the run as admin checkbox is disabled). Don't do this if you care about security ...

Well after reinstalling everything again last night in the C:\World of Warcraft folder I began patching and the first patch went right in to that folder; however, the subsequent patches went in the C:\Users folder again. Oh well, as long as nothing else goes there I will be happy especially now that I have symbolicly linked some of the folders.
