Hi there, well im not too sure for what reason you are trying to hide a user. But I will give you my solution that worked for my purposes. Basically I had created some extra accounts for network shares and for no other reason, so there was no need for the accounts to show up on the welcome screen. To fix this I right clicked on "My Computer" and selected "Manage". From there go to your user settings and edit the desired user to be hidden. In thier account type, remove "Users" from the type and add them to the "Remote desktop users" group. Make sure they aren't an administrator either. Well hope this helps.
