We have seen the problem with our laptops where an HP system encrypted with a Enterprise version of Mcafee Endpoint Encryption gets HP protect tools (personal version of safeboot component) installed and messes up the system. We do not install HP protect tools on laptops, but my guess it is a HP software update offered by there updater program gets installed when notifying users of important updates. When this happens the user cannot login as the wallpaper has been changed and the opportunity to type the user name and password has been changed to a list of users and a pin code. Even when booting to the emergency boot disk to do a emergency boot loggin screen this is modified. The way we get around this is to authenticate from a database object in the emergency boot disk or to just to an emergency recovery from the laptop bootscreen to get into windows. You must decrypt the laptop, remove the HP protect tools and start all over. This is a pain when all of a sudden dozens of machine may get this update installed and brick the laptops.
It would be nice for HP and Mcafee to work out something between their home product and their corporate product so that to prevent this from happending. Anyone else had these woes?
