We are running a Horizon View 5.2 Environment. We are running in kiosk mode. The pools are Win7 64-bit , floating, non-persistent, refresh at logoff settings. I have a pool of about 50 VM's at the moment and are intended to grow soon. The issue i'm having is that when a user logs in, they sometimes get a message "you must restart your computer to apply these changes" 
. This doesn't happen consistantly but often enough that this can keep users in an endless loop. At first I thought that it might be that it installed the USB Mouse and Keyboard passing through to the VM and installing the drivers. But if that was the case it would do it all the time. Also I'm using a login script to map the printers so i'm not too sure if that is the issue. Any advice?
